Government Supervision on Explosive Enterprises’ Immoral Behaviors in E-Commerce Enterprises: An Evolutionary Game Analysis

Explosive enterprises’ immoral behaviors in the online shopping market are widespread and have not been effectively solved. Especially in developing countries, there is a direct relationship between massive immoral behaviors and the inefficiency of government supervision. Using an evolutionary game, this paper finds that immoral behavior is more likely to spread in online markets than in traditional markets. Only when government supervision and punishment are large enough and government’s punishment for the illegal enterprise exceeds extra supervision costs that government pays, explosive immoral behaviors can be curbed. Additionally, consumer support is an essential factor in improving the efficiency of government supervision. /is study sorts out the interactions between e-commerce market participants and the government, obtains a path to achieve efficient government regulation, and offers management insights. /e findings can serve as a reference for ensuring order in the emerging online shopping market and can also provide theoretical references for future related research.


Introduction
With the development of the internet economy, online shopping has become a mainstream consumption method, which has increased the flexibility of shopping [1] and also reduced shopping time and shopping cost for consumers [2]. According to the 2017 World E-Commerce Report released by China International Electronic Commerce Center (CIECC), the global online retail transaction volume reached $3.5 trillion in 2019, accounting for 14.12% of the total global retail sales. In most developed countries, more than half of the population buys goods and services online. Among them, the growth rates of e-tailing in India, China, South Korea, and the United States were 31.9%, 27.3%, 18.1%, and 14.0%, respectively, and online shopping has become a globalized form of consumption (https://www.chyxx.com/ industry/202010/902336.html). In recent years, internet and digital technologies have developed rapidly in China, and the online shopping market in China is also expanding rapidly. By the end of 2019, the scale of China's e-commerce transactions and online payment transactions reached CNY 34.81 trillion and CNY 249.88 trillion, respectively (https:// www.chyxx.com/research/202009/897364.html). e scale of China's digital economy added value reached CNY 35.8 trillion, which has steadily ranked the second in the world. Some organizations predict that, with the impact of big data, cloud computing, artificial intelligence, blockchain, and other technologies on the online shopping market, online shopping will become the main shopping method in the future. e proportion of online shopping in total retail sales of consumer goods is expected to reach 20%-25% in 2020.
At the same time, the economic and ethical consequences of enterprises' immoral behaviors in network markets are more serious than those in traditional markets. Most directly, the massive expansion of enterprises' immoral behaviors will reduce national tax revenue on a large scale, which leads to massive economic losses. For example, research by the UK's Center for Economic and Commercial Research showed that, in 2016 alone, counterfeit goods caused British to lose £17.3 billion, reducing employment opportunities by 72,000 (http://www.independent.co.uk/ money/counterfeit-goods-tempting-danger-a7473751.html). It is easy to overlook that enterprises' immoral behaviors in network markets can destroy the ethical climate of the market [3], which can create a vicious cycle. On the one hand, enterprises' immoral behaviors can elicit immoral retaliation from consumers [4]. Consumers' perceptions of corporate behavior are fundamentally rooted in morality [5], and consumers who are subjected to enterprises' immoral behaviors can have a desire for revenge and retaliation [6], thus making the online shopping environment more chaotic. On the other hand, the process of spreading immoral behavior in network markets is similar to the process of virus spreading [7]. Once the fraudulent profiteering is not punished promptly, the negative incentive will spread contagiously in the society, forming "explosive immoral behaviors (EIBs)." EIB is a phenomenon in which economic actors act to the detriment of others while maximizing their own utility [8].
ere are many causes of EIBs, such as asymmetric information between supply and demand [9], corporate ethical failures [10], excessive corporate pressure [11], ineffective government regulation [12], and consumers' desire to purchase counterfeits [13]. Among them, information asymmetry is a prerequisite for the existence of such problems. However, due to the inaccessibility of online goods and the mixed nature of product information, the asymmetry of information between merchants and consumers in online marketplaces is exacerbated, ultimately resulting in market failures [14,15]. is is demonstrated, on the one hand, by the fact that product quality problems have been generalized in the network market. In 2018, GAO staff in the United States conducted a study (the report can be retrieved from http://www.amz123.com/thread-48343.htm? sort � desc). ey secretly purchased four branded goods (Nike Air Jordan sneakers, Yeti Mug, Urban Decay cosmetics, and UL-certified mobile phone chargers) from five popular e-commerce platforms, namely, Amazon, Walmart, Sears, Newegg Network, and eBay, and the results showed that 20 of the 47 products purchased were fakes. In a survey in the UK, 75% of respondents reported that they had bought fakes (the report can be retrieved from https://k.sina. cn/article_6474654027_181eb614b00100659f.html? http�fromhttp). A new study by Velocity MR, a market research firm in India, found that 30% of e-commerce products in India are fakes (the study can be retrieved from https://www.cifnews.com/article/34924). In China, according to the survey, 77.8% of e-commerce platforms have fakes on sale, and 98% of online customers have purchased fakes (the report can be retrieved from http://www.kjeport.com/ detail/article/2015_1/1_26/2038796_1.shtml). e other hand of EIBs is that ethical misconduct in the network market has expanded, including distortion of goods display information, ethical misconduct of big data marketing, and large-scale tax avoidance. For example, in 2002, Amazon was exposed to the fact that the purchase price of the same item for members would be higher than the purchase price for nonmembers (the study can be retrieved from https://www. researchgate.net/publication/262493771_When_big_data_ meets_dataveillance_ e_hidden_side_of_analytics). And in 2019, a social survey in China showed that 88.32% of the respondents believed that "overcharging familiar customers" through big data was widespread, and 56.92% of the respondents said they had been "overcharged" (the report can be retrieved from http://news.timedg.com/2019-03/28/ 20821145.shtml). As seen above, the phenomenon of EIBs in the network market is intensifying. is will make the lawabiding enterprise management behavior unsustainable, which not only seriously affects the competitive environment of the online shopping market but also provides reasons for government regulation.
In 2017, UK police have shut down 28,000 websites selling counterfeit goods, more than 4,000 of which were set up by stealing customers' identity information and using their names. In 2019, the E-Commerce Law of the People's Republic of China came into effect to maintain order in the network market. In 2020, the US signed the first Executive Order 19304 (E.O. 13904) to stop the flow of counterfeit goods and other contraband into the US marketplace. e executive order focuses on combating counterfeit goods traded on third-party online e-commerce platforms, including Alibaba, Amazon, and eBay. However, the EIBs in the network market have not been stopped. is is because the attitude of enterprises toward government supervision may be disobedience or manipulation besides compliance [16]. Especially when the target of government supervision is not a minority group in the market, the regulatory authority will face an awkward situation of lawlessness, which more easily leads to the failure of regulation and enforcement. Meanwhile, government supervision can incur substantial costs, and ineffective or inefficient regulation may even reduce social welfare. erefore, it is crucial to find the right and efficient path of governmental supervision to mitigate and curb EIBs in the network market. e main contributions of this paper are as follows: (i) is study elucidates the intrinsic logical relationship among the network market characteristics, the e-commerce enterprises' behaviors, and government regulation in order to better analyze the causes of current government supervision inefficiencies (ii) is paper analyzes the evolutionary process and internal mechanism of EIB through evolutionary games, highlights the role of government supervision in curbing EIBs in online markets, and obtains a path to achieve efficient government regulation (iii) is paper uses the Chinese government's regulation of EIBs in online markets as an example to verify the results obtained in the evolutionary game and to provide some managerial insights for countries where EIB regulation is inefficient or even ineffective e study is structured as follows: the literature review is presented in Section 2. Section 3 gives a dynamic game 2 Complexity model for the choice of immoral strategies of large-and small-scaled enterprises to analyze the inherent relationship between enterprise behaviors and government supervision. In Section 4, the evolutionary game model is constructed, and an effective strategy for the government to regulate the network market is given. Finally, Section 5 gives conclusions and management insights.

Literature Review
e purpose of this paper is to clarify the inherent logical relationship between the characteristics of enterprise behaviors, network market characteristics, and government regulation and to explore the feasible conditions and implementation paths for government supervision of the network market. erefore, in this section, whether EIBs in the network market require government supervision will be clarified, and the contribution and shortcomings of the literature on government supervision in the network market will be summarized.
Some scholars have focused on the managerial value of organizational ethics in response to enterprises' immoral behaviors in traditional markets [17,18] and have insisted that the market is the best regulator of immoral behaviors rather than the government [19,20]. However, online marketplaces differ from traditional markets. Mavlanova et al. [21] pointed out that the short duration of a single transaction when shopping online makes it more difficult for consumers to identify fraud signals. Meanwhile, Bergh et al. [22] argued that online sellers lack the awareness to recognize fraud signals. As a result, EIBs in the network market are more likely to arise and more insidious [23]. Another segment of scholars has noted the privacy risks of online marketplaces. Walsh et al. [24] concluded that the current federal and state laws in the United States are unable to protect the privacy of online buyers and highlighted the role of government regulation in protecting privacy. Mutimukwe et al. [25] suggested that the perceived privacy risk of e-marketplace users reduces their purchase utility. Anic et al. [26] showed that online shoppers want less privacy disclosure and that government regulation is very weak on privacy aspects of online marketplaces.
Previous studies generally agree that the emergence of online marketplaces has exacerbated EIBs of firms and caused market failures [27]. Calkins et al. [28] argued that although market regulators have more information about fraudulent transactions than government regulators, they have no incentive to proactively check for extensive online sellers who trade counterfeit goods. González [29] similarly believed that commercial interests also prevent the implementation of market regulation. To et al. [14] and Safaei and oben [7] showed that immoral behaviors in online shopping markets are more likely to arise and spread as information asymmetry between merchants and consumers is further amplified, which leads to EIBs and market failures.
us, while market regulation shows great strengths and potential in combating fraudulent transactions, it is still exposed to the general weaknesses of commercial self-regulation. Only government intervention in the network market to regulate businesses is likely to create new constraints on profit-seeking behavior and thus mitigate EIBs [30].
In the research related to government regulation in the network market, some scholars believed that the law is a key factor in regulating immoral behaviors. According to the empirical analysis on data from 30 countries, Oxley and Yeung [31] found that the law can effectively promote the healthy development of e-commerce. Martinsons [32] believed that forceful regulation and explicit law are the important conditions of e-commerce development. Examining how e-commerce law should be developed in the United States, Ribstein and Kobayashi [33] argued that the e-commerce law should be enacted by states rather than federal. e flexibility and variability of state lawmaking and competition between state legislatures can contribute to government regulation. AlGhamdi and Drew [34] pointed out that the lack of explicit regulations and ineffective government supervision are key factors affecting the immoral behaviors of e-commerce enterprises. Agrawal et al. [35] suggested that the government needs to participate in the development of e-commerce rules within the legal framework. Kim [36] noted that legal changes should be used for the maintenance of e-marketplace stability and explored how the government can regulate the use and identification of electronic signatures. Additionally, some scholars have given other suggestions for the government to regulate immoral behaviors in the network market. In terms of how to improve government supervision efficiency, Weiser [37] believed that public institutions need to cooperate with private sectors with technological advantages to improve government supervision efficiency. Marsden [38] proposed that the public institutions, private sectors, and civil society institutions should jointly participate in the supervision of the network market to form a supervision mode of collaborative management.
In summary, for immoral behaviors in the network market, the extant literature mainly discussed the importance of government supervision and its key elements from a macroperspective. Few scholars probe into the inherent logical relationship between government supervision and EIBs and explore the specific implementation of the government supervision mechanism. It is believed that the current inefficiency of government supervision is related to the lack of analysis of the evolutionary process and mechanism of e-commerce enterprises' immoral behaviors from a microperspective. erefore, this study uses the evolutionary game as an analysis tool to uncover the inherent mechanism of e-commerce enterprises' immoral behaviors and government supervision. A stable game strategy to improve the efficiency of government supervision and corresponding implementation measures are proposed. the lower threshold of entry and exit. Consumers are faced with too much virtual data to make sensible choices, which makes the e-commerce enterprises' EIBs present the characteristics of universality, diversity, and difficulty to regulate. e game process of government supervision and e-commerce enterprises is illustrated with figures. Assume that e-commerce enterprises can choose two strategies: one is to disclose true quality information of products, and this strategy is marked as MO; the other is to provide false quality information of products, that is, the enterprise adopts the immoral behavior, and this strategy is marked as IM. Suppose there are two competitive enterprises of E1 and E2 in the network market, and their scales and costs are different. Assume that E1 is large in scale and low in cost, and E2 is large in scale and high in cost. When the degree of government supervision is S, the strategic choices and profits of the two enterprises are shown in Figure 1.
Obviously, when MO is adopted by two enterprises, the profit of E1 is greater than that of E2. When both enterprises choose IM, the probability of E1 being discovered and penalized is greater which is illustrated by the larger slope in the profit curve of E1 than E2. When adopting immoral behaviors, small-and medium-sized enterprises (SMEs) are more difficult to supervise. As can be seen from Figure 1, SMEs will give up fakes only when S > S * * .
As can be seen from Figure 1, when the degree of government supervision is small (0 < S < S * ), two enterprises will choose IM, and the profit of E1 is greater than that of E2; as S increases, the profits of both enterprises adopting IM will decrease, and the profit of E1 decreases more. When S ∈ (S * , S * * ), it is more advantageous for E1 to choose MO, while E2 still adopts IM. When S > S * * , two enterprises will choose MO, and when the degree of government supervision is large enough (S > S ″ ),E1 with IM is more severely penalized, and its profit will be smaller than E2 with IM.
In order to further explain the government supervision strategy, a more detailed discussion is given to connect the government supervision and the immoral costs of different enterprises. It is assumed that there are e-commerce enterprise L1 and e-commerce enterprise L2 with different scales and costs. Enterprise L1 is small in scale and high in cost, whose cost is C L1 and profit is Δπ L1 when adopting IM. Enterprise L2 is large in scale and low in cost, whose cost is C L2 and profit is Δπ L2 when adopting IM. It is assumed that Δπ L2 > Δπ L1 and C L2 < C L1 , and the degree of government supervision is S. e relationship among S, the profits, and the costs when enterprises adopt IM is shown in Figure 2.
When the cost and the profits of enterprises adopting IM are located in region I, there is C L1 > Δπ L1 and C L2 > Δπ L2 .
is means that the enterprise is not profitable when adopting IM. Even if the government does not supervise, the enterprises will not adopt IM. Region I is regarded as an invalid zone of IM.
Region II represents C L1 < Δπ L1 , C L2 > Δπ L2 , and is region is the invalid zone for L2 adopting IM, so L2 will adopt MO. Because S is weak, L1 can gain profit by IM, so L1 will adopt IM.
Region IV represents C L1 < Δπ L1 , C L2 < Δπ L2 , and Δπ L1 < S < Δπ L2 . In this region, both L1 and L2 can gain profits from IM, but S is effective for enterprise L1 and ineffective for enterprise L2. So, L1 will adopt MO and L2 will adopt IM. Region is region is the invalid region of L2 adopting IM, so enterprise L2 will adopt MO. Although L1 can obtain profit by IM, L1 still adopts MO because S is strong. erefore, this region is an effective region of government supervision.
Region VI represents C L1 < Δπ L1 , C L2 < Δπ L2 , and Δπ L1 < Δπ L2 < S. In this region, although both L1 and L2 can obtain profit by IM, L1 and L2 have to adopt MO due to the stronger government supervision S; that is, this region is also an effective region of government supervision.
Region VII represents C L1 < Δπ L1 , C L2 > Δπ L2 , and Δπ L1 < Δπ L2 < S. e region is the invalid region of L2 adopting IM. Although L1 can gain profit, government supervision S is very strong, and both enterprises adopt MO. is region is also an effective region of government supervision.
rough the analysis of the models, it is indicated that when the competitive enterprise chooses IM, the enterprise choosing MO obtains a lower profit. When the declining speed of the enterprise's profit is slower by the increase of government supervision, the enterprise will adopt IM in a larger range (0 < S < S * * ); otherwise, the enterprise will adopt IM in a smaller range (0 < S < S * ). at is to say, the competitor's choice of IM can stimulate other enterprises to adopt IM, thus inducing the EIB. Government supervision has become an important factor affecting enterprise strategy choices.

The Evolutionary Game between Government Supervision and Strategy Choices of E-Commerce Enterprises
In practice, government supervision on e-commerce enterprises needs costs, which directly affect supervision effectiveness. In the process of supervision, the government and the e-commerce enterprise constitute a dynamic and repeated game relationship, where two parties constantly correct their strategies through trial and error to maximize their own profits. erefore, an evolutionary game model of government supervision and strategies of e-commerce enterprises is constructed to find effective equilibrium for government supervision.
In order to further discuss the effectiveness of government supervision, the degree of government supervision and enterprise profit are separated. For any e-commerce enterprise in the network market, it is assumed that the e-commerce enterprise has two strategies in the competitive market, namely, MO and IM. If e-commerce enterprise i adopts MO, the profit is π i ; if e-commerce enterprise i adopts IM, the profit can be increased by Δπ i ; that is, the profit of adopting IM is π i + Δπ i . For different choices, the government implements different degrees of supervision. e degree of supervision and supervision cost are generally corresponding; that is, the greater the degree, the greater the cost and the higher the probability of successful supervision. For the convenience of analysis, the supervision cost is used to reflect the degree of supervision, which does not affect the conclusions. Assume that when government supervision is successful, the supervision cost is S g ; when government supervision fails, the supervision cost is S k . When government supervision is successful and all e-commerce enterprises adopt MO, the network market achieves the optimal operation, which will promote the development of the network economy, the increase of social welfare, and the enhancement of consumers' trust and support to the government. All these can be seen as the utility of government supervision. And suppose f is the utility of government supervision, namely, the degree of consumers' support to the government. When the government supervision is successful, if an enterprise adopts IM, the enterprise will be punished, and the punishment is Based on Hofbauer et al. [39] and Shen and Wang [40], the profit matrix of government-supervised e-commerce enterprises is shown in Table 1.
In an evolutionary game model, the strategies of participants are mutually influenced. e growth rate of a certain strategy depends on the fitness, i.e., the strategy that produces higher profit has a higher growth rate. As a result, the government and the e-commerce enterprise can increase their profits by mimicking the strategies that succeed.
It is assumed that the e-commerce enterprise can randomly and independently choose MO or IM and repeat the game in the market. Assume that the probability of e-commerce enterprise 1 choosing MO is p, and the probability of choosing IM is 1 − p; the probability of successful government supervision is q, and the probability of supervision failure is 1 − q. According to the Malthusian equation [41], the growth rate _ p/p of e-commerce enterprise i choosing MO should be equal to its fitness, e 1 A q, 1 − q T , minus its average fitness, p, 1 − p A q, 1 − q T . e 1 � [1, 0] represents the e-commerce enterprise choosing MO with 100% probability. en, the profit matrix of e-commerce enterprise i is Similarly, considering the growth rate of government's supervision success, _ q/q, it can be derived that . e local stability of the system at equilibrium is analyzed using the Jacobian matrix [42]: It can be derived that e evolutionarily stable strategy (ESS) of the system is analyzed as follows: (i) When f < S g − S k , according to _ p � 0 and _ q � 0, the system equilibrium is (0, 0), (0, 1), (1, 0), (1, 1), and e ESS analysis is shown in Table 2.
(2) When F − S g + S k < 0, 0 < Δπ i < F < S g − S k . e ESS analysis is shown in Table 3.
e ESS analysis is shown in Table 4.
ESS analysis is shown in Table 5.
From the analysis of Tables 2-5, the ESS can be reached only when the consumer support for government regulation satisfies f > S g − S k , However, it is worth noting that when 0 < Δπ i < F < S g − S k , (0, 0), i.e., government supervision fails and the e-commerce enterprise adopts IM, is also the ESS. Actually, this situation is the other extreme of the network market with EIBs of e-commerce enterprises, which is caused by the weaker government punishment F < S g − S k . erefore, to ensure the normal operation of the network market, (1, 1) must be regarded as the only ESS of the evolutionary game, that is, the following conditions must be met: (i) e government must punish enterprises that adopt IM. Only when the government's punishment is greater than the profit obtained by IM, i.e., F > Δπ i , enterprises will choose MO. Moreover, the higher the punishment imposed by the government, the greater the impact on the e-commerce enterprises and the fewer the enterprises adopting IM. (ii) e degree of government supervision needs to be large, i.e., S g > S k > 0. Only when the government supervision reaches a certain level, supervision can be effective. If government supervision is weak and of no practical significance, the supervision is just a thankless task.
(iii) When the government supervision is enhanced, the increased supervision cost S g − S k has to be compensated to maintain a high level of supervision. is requires the government to punish the enterprises that adopt IM at a punishment more than the increased cost, i.e., F > S g − S k > 0. (iv) e consumers' support that must be met, f > S g − S k , is an indispensable condition for successful government supervision. e timely and comprehensive feedback of consumers not only directly affect enterprises' reputation but also provide evidence for authorities of the government supervision, reducing the supervision cost and improving supervision efficiency.

Practice and Discussion
In the previous section, the conditions for the government to effectively supervise EIBs in the network market are obtained through an evolutionary game: the government punishes enterprises with immoral behaviors strongly enough, the degree of government supervision is high enough, the government needs to be compensated for the supervision cost, and consumers should support government supervision through feedback. Previous studies suggest that governments in developing countries should strengthen the regulation of online shopping markets compared to developed countries [35]. In most developing countries, e-commerce markets lack clear regulations and effective government oversight [34]. Moreover, counterfeit products damage more the reputation of developing countries than the economy. erefore, it is more important for governments in developing countries to take strict measures to regulate online counterfeiting and other EIBs. Studies have shown that market self-regulation of counterfeit products in China is inefficient [43]. Based on this, the Chinese government's supervision on EIBs in the network market is used as a typical example in the section to verify the results obtained from the evolutionary game and to provide some managerial insights for countries where EIBs' regulation is inefficient or even ineffective.
From the practice in China, e-commerce platforms play an important role in combating immoral behaviors, and government supervision is indispensable. Besides, e-commerce platforms play the due role only when government supervision is effective. For example, Alibaba, a giant Table 1: Profit matrix of government-supervised e-commerce enterprises.

Government supervision Success Failure
Strategies of e-commerce enterprises MO Alibaba also conducts random inspections of goods through big data algorithms and initiates about 100,000 random inspections every year. CNY 100 million is invested to purchase goods sold on the platform. Once fakes are found, the goods will be removed, and the e-commerce enterprise will even be driven out of the platform (the report can be retrieved from http://paper.ce.cn/jjrb/html/2018-08/29/ content_371267.htm). Alibaba's antifaking measures were even appreciated by Doug Collins, the vice-chairman of the US House Judiciary Committee (http://www.sofreight.com/ news_36233.html). Despite this, fakes on Taobao (http:// www.taobao.com), Tmall (http://www.tmall.com), and other websites are still difficult to eliminate, which is directly related to the lack of rigorous government supervision.
(i) e government's punishment for enterprises with immoral behaviors is too weak, leading to the existence of EIBs in the network market.
Different from traditional brick-and-mortar enterprises, e-commerce enterprises directly open stores in the network market, most of which are SMEs [44]. ese e-commerce SMEs just need to meet the entry and selling rules and obtain the qualifications of the e-commerce platforms, while the offline enterprises must face the supervision of different authorities such as the Industry and Commerce Bureau and Tax Bureau and have to undertake Uncertain point Table 4: e stability of the equilibrium in Case 2-(1). Table 5: e stability of the equilibrium in Case 2-(2). Moreover, the illegality cost of e-commerce platforms selling fakes is also low, and platforms bear little joint liability; even some e-commerce enterprises are removed from the platform due to EIBs. In European countries, in the judicial decisions of similar cases, the e-commerce platforms are generally required to undertake joint liability. For example, it was reported that in 2008, a court in Paris, France, ruled that eBay infringed on the rights of the LVHM Group and is enforced to compensate the company with $61 million for selling fakes (the report is at http://news.winshang.com/html/044/ 2510.html). Besides, the e-commerce platforms are the most profitable enterprises, and even they sell fakes. Although some counterfeit information is transferred to the platform staff, they even cover up the immoral behaviors to ensure their own profits.
(ii) e low-degree government supervision on EIBs leads to inefficiency. According to statistics, in 2016, Alibaba Platform Management Department used big data and manual reexamination methods to find out 4,495 enterprises that produce and sell fakes; their sales were far superior to the standard to be sentenced to jail (CNY 50,000) (the report is at http://b2b.toocle. com/detail--6432092.html). Among them, the authorities accepted 1,184 cases and only can punish 469 cases under the current regulations. ere were only 33 cases that can be confirmed as criminal judgments through public information, accounting for less than 1% of cases that can be punished. In the cases that have been sentenced, 37 of 47 were suspended, with a ratio of 79%. Why the degree of government supervision of online shopping anticounterfeiting is so low? In addition to the hysteresis of the current law, this is also related to the performance evaluation of GDP growth and employment. All kinds of EIBs can meet the consumption needs of migrant workers and new residents in the process of urbanization. Moreover, the employment rate is increased by low-quality jobs due to the simplicity of producing and selling fakes. According to the data released by Zhiyan Consulting, the number of employees of Chinese WeChat shops exceeded 20 million in 2017 (the report is at http:// www.bbtnews.com.cn/2019/0531/304162.shtml). It is estimated that, by 2024, the number will reach 52 million. e massive participation has prompted the development of e-commerce enterprises and also has caused many problems, such as tax evasion, sales of fakes, and disclosure of personal information. Many enterprises that produce and sell fakes are fully qualified and relatively large in scale, and some are even protected by the local governments. For example, in 2018, more than 100 enterprises producing condiments in a town in Tianjin, China, were closed. According to the survey, these enterprises were fraudulent for more than ten years, and the local government left them alone until they were exposed by the media (the report is at http://www. xinhuanet.com/fortune/2018-08/29/c_1123346277. htm). (iii) e cost of government supervision cannot be compensated, leading to a loss of sustained motivation for supervision.
On April 14, 2016, the "QSIQ 12365 Complaint and Report Advisory Network" was launched in China. rough this website, consumers can check the information of enterprise product qualification and can also consult, complain, and report to the regional quality control departments. At the same time, to facilitate consumers to check the information of enterprise product qualification, Alibaba and other four e-commerce platforms were required to sign a cooperation agreement as a way to achieve the docking of e-commerce platforms and quality control website (the report is at https://www.sohu. com/a/69427874_350719). However, until today, e-commerce platforms have not realized the function of querying the product qualification, and the quality control website has not been effectively developed and used, which indicates that quality 8 Complexity control in China has not achieved the expected results. On the one hand, this is due to the lack of clarity in the definition of responsibilities of government departments and the imperfect regulatory support system. On the other hand, the high cost and low return of government regulation also make the government have no incentive to regulate. Similarly, on January 1, 2019, the Chinese government introduced the E-Commerce Law, which explicitly brings EIBs such as data falsification into the scope of legal regulation. However, due to the high cost, government regulation is hardly effective as expected. In contrast, China's Antimonopoly Law was put in effect in 2008 and has been enforced for 12 years, with relevant administrative precedents amounting to CNY 12 billion. is makes the regulatory costs of government regulation compensable, thus making the regulation effective and sustainable. It is proved by the Chinese experience that government regulation can only be effective and sustainable if the costs of government supervision are compensated.
(iv) e lack of consumer rights and responsibilities contributes to the prevalence of counterfeit goods.
At present, customers hate fake foods and medicines but prefer low prices when purchasing other kinds of goods. In particular, consumers who are willing to buy fakes that involve intellectual property rights do not take it as a serious behavior. According to China's annual survey of Day for Consumers' Rights and Interests in 2019, less than 60% of consumers choose to protect their rights after buying fakes, and 16.11% of consumers continue to use fakes (the report is at https://www.thepaper.cn/newsDetail_forward_3141915). In the above survey, 33.59% of consumers believed that the low price is the main reason why counterfeit goods are difficult to ban.
In response to the increasingly serious e-commerce EIBs, the Chinese government has taken measures to increase the degree of government supervision and punishment to regulate the network market, which has already achieved preliminary success. Since October 2017, the National Development and Reform Commission has issued four blacklists for special management of untrustworthiness in the field of e-commerce, involving a total of 1092 enterprises (the report is at http://field.10jqka.com.cn/20181106/ c607973048.shtml). On May 14, 2018, the National Development and Reform Commission, the Central Network Information Office, the Ministry of Industry and Information Technology, etc., a total of 8 departments, jointly issued the Notice on Strengthening Special Governance Work on Untrustworthiness in the E-Commerce Sector to crack down illegal and untrustworthy behaviors in the field of e-commerce (the report is at http://www.sohu.com/a/ 273707363_100019209). In June 2018, the General Administration of China's Market Supervision, the National Development and Reform Commission, the Ministry of Industry and Information Technology, etc., a total of 11 departments, jointly issued the Notice on Printing and Distributing the 2018 Network Market Supervision Special Action (Net Sword Action) Program, focusing on rectifying online infringement and false propaganda, false illegal advertising, etc. e Electronic Commerce Law of the People's Republic of China, which was officially implemented on January 1, 2019, regulates the rights and obligations of e-commerce enterprises and e-commerce platforms. In 2016, Alibaba provided a total of 4495 enterprises with EIBs whose sales exceeded CNY 50,000 to the national public security organizations. In 2017 and 2018, these data dropped to 1910 and 1634 (he reports are at http://www.cicn.com.cn/zggsb/ 2018-01/18/cms103803article.shtml and https://baijiahao. baidu.com/s?id�1622256698847441370&wfr�spider&for� pc).
Among other countries, due to the lack of government supervision in the network market, Russia can only rely on several large-scaled platforms to spontaneously fight against fakes. Group-IB data showed that, in 2017, Russia's online counterfeit transactions exceeded USD 1.5 billion, a 23% increase from 2016 (the blog can be retrieved from https:// blog.csdn.net/mozhe_/article/details/83105588).
e US government has strengthened the government regulation on the network market. On April 3, 2019, President Trump signed a memorandum aiming at cracking down on online counterfeit transactions. It is recommended to enhance government supervision or legislative changes to better combat the sale of fakes. (the report is at https://www. stopfakes.gov/article?id�Presidential-Memorandum-on-Combating-Trafficking-in-Counterfeit-and-Pirated-Goods-Opportunity-for-Stakeholder-Comments). Germany, whose network market operates in a good order, has imposed severe legal sanctions on the sale of fakes and ordered enterprises to return the fakes unconditionally within 14 days. Meanwhile, the blacklist of online shops selling fakes is established, and the public can expose online shops for selling fakes on the supervision website, making shops to be investigated and punished by the judicial agency.

Conclusion and Policy Suggestion
From the aforementioned model analysis and case discussion, it is found that, in many countries, especially in developing countries, inefficient government supervision is one of the critical factors for e-commerce enterprises adopting immoral behaviors. When e-commerce enterprises gain profits more through IM than through MO, EIBs appear. Only when government supervision and punishment are strict enough and punishment for the enterprise adopting IM is higher than the extra cost of government supervision, EIBs will be curbed. Besides, consumers' support is an essential factor in improving the efficiency of government supervision. e governance of EIBs is a systematic project, and it is not enough to rely solely on government supervision. It is necessary to construct a new mechanism of social cogovernance of "enterprise initiative, industry self-regulation, social supervision, and government supervision." Note that the government's attitude and behavior about EIBs in the network market play an important role in guiding and
