The Synergy between City Human Resources and City Economy Development Based on the City Marketing : The Case of Chengdu

City human resources and the city economic development have a synergistic effect to attract high-quality talent and to encourage the sustainable development of the urban economy in the city marketing. Based on synergetics, we find out the evaluation indexes between the city human resources subsystem and urban economic development subsystem and constructed the evaluation system and model, and then used the yearbook data of Chengdu human resources and economic development from 2002 to 2012 and carried on empirical research. The results show that the level of coordinated development is weak between city human resources and city economic development at Chengdu, but it keeps rising slowly. The strong policy support shall be provided to Chengdu human resources and economic development by Chengdu government.


Introduction
The city is an important node and fulcrum of economic activities, political life, and cultural development.With the economic globalization, talents have been attracted by the city to expand its human resources and to promote the development of economy, so talent is critical to economic and social progress of the city.As a platform of the talent and economic development, the city should implement city marketing, in order to meet the demands of city human resources and economic growth.Therefore, it has a crucial practical significance for promoting the city economic growth and the city sustainability development to measure and test the synergy degree between city human resources and city economic development.
China is facing the pressure of urbanization; how to improve city branding, to attract high-quality talent, and to stimulate and promote economic sustainable development are an essential problem now.Chengdu is an important economic center in the West; the status of city human resources and economic development directly impact on urbanization level, and will affect the process of Chengdu's dream about "Construction of World Modern Garden City." Especially regarding the Wenchuan earthquake in 2008, whether it had impact on Chengdu human resources and economic development is just an interesting question.Talent, as a major competition in the world, has a huge promoting and pushing effect on the economic development.Under the background of city marketing, talent aggregation effect promotes the development of an urban economy effectively.Evaluation of city human resources and economic development has important practical significance for making talent introduction policy of the city and opening the municipal fiscal place.Accordingly, the research technique route was described about the synergy degree between city human resources and city economic development, as shown in Figure 1.

Figure 1: The research technique route.[1].Later, Knyazeva advocated that synergetics will go for a wide application field [2].Today integration concept and synergetic theory are largely followed in modern management [3], such as a synergetic model for implementing an environmental management, occupational health, and safety management systems [4].Some researchers paid great attention to the synergy development among the industry, scientific innovation, energy resources, and self-organization.For example, Rofiqul Islam et al., Varga, and Kuehr studied the synergy on the recovery and renewable resources [5,6]; di Vita and Elíasson and Turnovsky focused on the synergy development of renewable resources and the technical substitution [7,8].To sum up, these studies try to use synergetics in management research but have yet to be further applied in technology and economy, business, and management studies.

City Marketing.
City marketing began in the 1930s, including three stages roughly, such as "Fragmented Promotional Activities, " "City Marketing Mix, " and "Towards City Branding" [9][10][11], and several academic schools came into being on the city marketing.For instance, in the school of political orientation, Ashworth and Voogd claimed that "essentially city marketing involves the establishment of a particular relationship between producers and consumers, that is both close and permanent.This in turn necessitates the study of both the spatial and organizational structures of the city as a product as well as the characteristics, market behavior, and needs of the identified users as consumers" [12].
In the school of economics, economic development as the ultimate goal of city marketing aimed at promoting urban growth in wealth [13,14].Specifically, Kotler mainly focused on two aspects between the economy (citizens, companies, and communities) and society (tourists and investors), analyzed the city marketing customers-the city human resources, such as local residents, employees, and investors.Meanwhile, Brotchie et al. scholars focused on city marketing to enhance city competitiveness and to promote the development of city economy [15].So the city marketing is the means to achieve a city policy; city managers break through the bottleneck of urban development through the use of various marketing strategies, to enhance competitiveness [16,17].In addition, Kavaratzis is interested in the theory of city brand [18], Zenker et al. researched the city marketing citizen satisfaction [19], and so on.According to these studies, some subjects attract the attention of the scholars, such as the concept and scope of city marketing, the relationship between city marketing and economic development, the relationship between city marketing and human resources, city branding, and the means and motive of city marketing.

Human Resources and Economic Development.
There exists a strong connection between economic growth and human development [20,21].Importance of human resource development can be undeniable irrespective of developed and underdeveloped economies [22].So the ultimate goal of economic progress is the sustainable development of human beings, and talent can effectively promote the development of economy.The relationship between human resource and economic development has been attracted by scholars from the perspective of macro.What is the relationship of it to the city?Manca and Fleisher et al. focus on the human capital and economic growth on region [23,24].It is worth noting that Fleisher studied a related question about China and suggested that talent introduction should be undertaken for the development of social economy about the city.
From what has been reviewed above, the existing research focuses on the relationship between human resource and economic development but has not been concerned with what the coordinated development of both does.So, this study uses synergetics theory and analyses the synergy degree of city human resources and city economic development to promote the orderly development of both under the background of city marketing.

Model Construction
According to the research synergetics [25,26], the model should include the changing of the associated elements between the subsystem of human resource and the subsystem of economic development, the order degree of order parameter, and the important influential factors between subsystems.
3.1.Order Parameters.Some indexes of the level of human resources development have been selected on the order parameters of the city human resources subsystem, such as quantity of city human resources, quality of city human resources, the demand of city human resources, and the supply of city human resources.Meanwhile, Some indexes of the level of city economic development have been found out about the order parameters of the city economic development subsystem, such as the management level of city economics, the level of city primary industry, the level of city secondary industry, and the level of city tertiary industry.Precise quantitative system is shown in Table 1.

Subsystem
Order Degree.The composite system is an organic whole of city human resources and city economic development within the jurisdiction area of a city.In this system, the subsystem of city human resources and the subsystem of the city economy interacted with each other.Therefore, the composite system on city human resources and economic development is expressed as  = ( 1 ,  2 ), where  1 represents the subsystem of city human resources,  2 is on behalf of the subsystem of city economic development, and  is a composite function.
The order parameter of the subsystem of city human resources and city economic development is it can describe the running state of the second subsystem () about city human resources and economic development, where   is upper limit and   is lower limit.There are   ≤   ≤   ,  ∈ [1, ] and  ≥ 2.
In addition, the indicator has two kinds: one is positive index.The order degree is better when the parameter values are higher; conversely, it is the lower.The other is negative index; the order degree is better when the parameter values are lower.Order degree of order parameter (  ) can be defined when order degree increases with   ,   − when order degree decreases with   , where   (  ) ∈ [0, 1]; its value is greater and its contribution is higher in systematic order degree.
Overall, the contribution of order parameter (  ) can be shown by   (  ).For using different forms of data, it is necessary to use the linear weighted sum method for data processing.The order degree model of subsystem is followed: (2) 3.3.Index Weight.At present, common methods include subjective values and objective method.The former has expert scoring method and Delphi method; the later include entropy value method, the standard deviation method, and CRITIC method [27].This study selected CRITIC method to weigh the index.Firstly, confirming the effect of indexes Among them,   represents the impact of the index () on the subsystem,   is half on the standard deviation of the index (), and   represents the correlation coefficient between the index () and the index ().The greater the   value, the more important it is to the subsystem.
Secondly, confirming the weight of index where   is the objective weight of the index (); then the weight coefficient was gained.

Synergy Degree
Model.Synergy degree model is suitable for the quantitative description of the system development and is a function of the independent variable of the order parameter.So the function value is the system synergy degree (SD).The subsystem order degree is    (  ) when the system is at a given initial moment; after a period of time or at the next moment ( +1 ), the subsystem order degree will be changed  +1  (  ): where SD ∈ [0, 1]; it embodies the synergy development between subsystems.When its value is close to 1, the level of synergy is very good between city human resources and city economic development.When its value is close to 0, the level is very terrible.It is noticed that the synergy degree is 0 when  +1  (  ) or    (  ) have some questions.

Empirical Study on Chengdu City
4.1.Sampling and Data.Marketing campaigns are great weapon for city marketing, such as the cultural events [28], sports events [29], the World EXPO [30,31], and conferences [32].Through careful planning, these one-time and serial marketing campaigns bristle with innovative themes capable of great effect.Not only it is newsworthy, but also it is an applicable standard in the city marketing.In this respect, Chengdu has gathered a wealth of experience in its promotion (Table 2).Many marketing campaigns have gotten the attention of tourists and investors, such as China Food and Drinks Fair every year, International Food & Tour Festival of China every year, Fortune Global Forum in 2013, and Olympic Games in 2015.Details are shown in Table 1.
Thirdly, confirming the synergy degree.Using the data Tables 5 and 6, the weight, and formula (2), the order parameter was drawn up.Specific data are shown in Tables 7 and 8 about an order parameter.
Finally, using the order parameter and formula (5), the synergy degree was calculated, respectively.Specific data are shown in Table 9. demonstrates that the human resources of Chengdu have been developing orderly direction.Just it was slowly and halfway down.It is notable that the order degree of subsystem was decreased in 2008; because of the earthquake, Chengdu was mistaken as "unsafe" city.With the policy support of brain gain and national disaster relief, the order degree presented a tendency of increasing in 2009.
Order degree of Chengdu economic development subsystem showed a good upward trend since 2002, but there Some city image Ads were created under the city marketing, such as "Chengdu, enjoy your life" in 2004 and "I love my city" in 2008.The advertising video especially showed the safety of city after an earthquake and helped recovery ability of economic development.After the Wenchuan earthquake, the economic development was not only attributed to the city marketing strategy, but also attributed to the financial support of the national strategy of Chengdu.Such as the reform pilot area of national urban and rural development, the policy on the development of the western region of China, and the postdisaster rebuilding work.Synergy degree of human resources and economic development of Chengdu is not stable, to some extent that is obviously low.The synergy degree presented a slowly rise from 2002 to 2007, but its absolute value is very slight and has great potential to increase.The synergy degree showed a gradual decline slightly from 2008 to 2011.Here, the economic development of Chengdu was rapid; the talent also has been progressing, but there were no consistent development, which is affected by the earthquake and aftershocks.In 2012, the order degree of both Chengdu human resources and Chengdu economic progress demonstrated a good upward trend.Overall, human resources and economic development of Chengdu are not completely synchronous, but it is at the low-level stage, so it is necessary to strengthen the city marketing strategy for promoting the development of the city.

Conclusions and Implications
Using the idea and method of synergetics, the model of synergy degree about city human resources and city economic development was established and the advance state of them was evaluated.These are a basement of urbanrural integration progress with the human resources policy and economic development strategy.At the same time, this study has its limitations; for example, the data are only from yearbook, the research is not covered with the social progress, and the index has yet to be further perfect.
In order to promote synergy and sustainable development of human resources and economic development of Chengdu, some work should be carried out by the government.Firstly, deepen the talent introduction policy, attract a large number of excellent talents, format talent accumulation effect, and safeguard the rights and interests of the people living standards, for promoting the sustainable development of human resources.Secondly, open the investment policy, attract the world high-tech enterprise, make the industry chain and industrial cluster, and create a sound ecological environment for investment.Finally, strengthen the synergy development of human resources and economy and promote the common development of both.
