In recent years, a new generation of information technology has provided sufficient technical support for the smart manufacturing industry. In order to promote the upgrading of China's pharmaceutical smart manufacturing industry, the direction of industrial upgrading and transformation will be discussed from the perspective of technological innovation. According to the input and output data of technological innovation in China's pharmaceutical manufacturing industry from 2007 to 2019, the DEA method is used to analyze the allocation of innovative resources in China's pharmaceutical manufacturing industry in recent years. The study found that the efficiency of technological innovation in China's pharmaceutical manufacturing industry fluctuated greatly from 2007 to 2019, with a low overall level and varying degrees of wasted resources. On this basis, an in-depth analysis of the system architecture of the pharmaceutical smart manufacturing industry under the Industry 4.0 environment was performed. Finally, four paths for the digital transformation of China's pharmaceutical manufacturing industry are proposed. Chinese pharmaceutical manufacturing companies need to use new technologies to carry out comprehensive intelligent upgrading and digital transformation to improve innovation efficiency.


Introduction
China's smart manufacturing industry has made some achievements in recent years. Smart manufacturing exerts a profound influence on the pharmaceutical industry, leading to the following three development trends [1][2][3]. e first is improving the intelligence and information levels of the pharmaceutical industry and popularizing manufacturing execution systems to the production processes, thereby achieving the whole-process monitoring and management of drug quality. e second is innovation of the production techniques and enhancing the applications of computer-aided drug design, 3D printing, and virtual reality during research and development (R&D). e third is increasing industry concentration, shifting the market structure of the pharmaceutical industry based on industrial integration, and promoting the pharmaceutical industry to the international market. Smart manufacturing in China's pharmaceutical industry is at the primary stage; characteristics of the pharmaceutical industry put forward loads of special needs on smart manufacturing. Competitive situations in China's manufacturing industry have become increasingly fierce, and production costs and labor costs have increased accordingly. Manufacturing corporates, including pharmaceutical corporates, have begun to use new technologies to improve production efficiency and strengthen product innovation and management capabilities, gaining competitive advantages [4]. Hence, the smart upgrade of the pharmaceutical manufacturing industry is crucial to the industry's long-term development in this context.
As the pharmaceutical industry becomes smarter in pharmaceutical production, promoting the smart development of pharmaceutical manufacturing corporates through pharmaceutical equipment and helping corporates transform from automated production to smart production has become the road to the smart development of pharmaceutical manufacturing corporates [5,6]. As a typical innovation-driven and technology-intensive industry, pharmaceutical manufacturing is characterized by high thresholds and high risks. Hence, it is difficult for a corporate to depend on its accumulation to break through the dilemma between R&D and continuous growth [7]. Innovation is the first driving force for development, and the pharmaceutical manufacturing industry is a critical carrier that can best embody technological competitiveness. Hence, technological innovation has become a decisive factor in the competitiveness of pharmaceutical manufacturing corporates. Continuous optimization and innovation of enterprise technology are the keys to ensuring the quality of medicine and improving efficiency.
Some factors restrict the current innovation and development of the pharmaceutical manufacturing industry in China, and the smart agglomeration effect must be expanded further. is paper deeply analyzes the current technological innovation input and output of China's pharmaceutical manufacturing industry. It evaluates the technological innovation efficiency of China's pharmaceutical manufacturing industry from 2007 to 2019 and clarifies the allocation of innovative resources in China's pharmaceutical manufacturing industry in recent years. Based on the evaluation results, combined with the development needs of the pharmaceutical manufacturing industry, we clarify the necessity of technological innovation and intelligent upgrading of China's pharmaceutical manufacturing enterprises and propose specific transformation paths. e innovation point is to help China's pharmaceutical smart manufacturing industry achieve industrial upgrading through theoretical analysis and empirical research from the perspective of accelerating technological innovation and improving the efficiency of technological innovation in the pharmaceutical industry.

Manufacturing Industry Technological Innovation. ere are multiple choices for corporate R&D innovation models, which should be comprehensively considered based on the specific R&D time, personnel, and R&D difficulty of the corporates. Corporate R&D innovation is a process of trial and error. According to different R&D subjects, R&D innovation modes can be divided into independent innovation, cooperative innovation, and imitative innovation. Independent innovation means that corporates develop products depending on their technical capabilities and realize the productization of R&D results on this basis, thereby gaining market recognition. Cooperative innovation is an innovative organization formed by cooperation among multiple corporates and research institutions [8][9][10]. Some large-scale and complex innovation activities often require cooperative innovation among multiple units, giving full play to their respective advantages, achieving complementary resources, and providing the possibility of successful innovation. Imitative innovation introduces new technologies through legal means under the influence of other corporates' pioneering innovations and improves the original technology system [11,12]. Usually, before imitative innovation, high-quality imitation is performed first. en, some entry points for improvement can be found.
Innovation activities of the pharmaceutical manufacturing industry are divided into two stages: the input stage and the output stage. e technological innovation of pharmaceutical manufacturing corporates requires the support of inputs such as funds and personnel. R&D expenditure and personnel input directly manifest the importance of a pharmaceutical manufacturing corporate to R&D, which is also the power source for future development. Using capital and personnel inputs to transform into knowledge output efficiently and economic output is undoubtedly the industry's lifeblood and the driving factor for developing pharmaceutical manufacturing enterprises [13]. e R&D internal expenditure and R&D external expenditure of China's pharmaceutical manufacturing industry during 2012-2019 are illustrated in Figure 1; the new products development expenditure and full-time equivalent on R&D personnel of China's pharmaceutical manufacturing industry during 2012-2019 are presented in Figure 2 (data source: China National Bureau of Statistics). Figure 1 shows that the total internal expenditure of R&D and external expenditure of R&D in China's pharmaceutical manufacturing industry showed a year-on-year growth trend from 2012 to 2019. Internal expenditure of R&D increased from 283.31 hundred million yuan in 2012 to 609.56 hundred million yuan in 2019, an increase of 2.15 times and an average annual growth rate of 11.57%. External expenditure of R&D increased from 33.86 hundred million yuan in 2012 to 110.62 hundred million yuan in 2019, an increase of 3.27 times, with an average annual growth rate of 18.43%, with the most significant increase in 2018. It shows that, in recent years, Chinese pharmaceutical manufacturing enterprises have attached great importance to independent innovation and cooperative innovation activities and have continuously increased capital investment to ensure the innovative development of enterprises. Figure 2 shows that the total expenditure on new products development in China's pharmaceutical manufacturing industry has increased year-on-year from 308.23 hundred million yuan in 2012 to 732.52 hundred million yuan in 2019, an increase of 2.38 times, with an average annual growth rate of 13.16%. It shows that China's pharmaceutical manufacturing industry has paid more attention to new products development and design investment in recent years, which is an essential guarantee for improving industrial innovation. Pharmaceutical manufacturing is a particular industry, and its innovation results must be tested through clinical trials, requiring an extended period. Products and patents owned by a corporate can serve as an essential indicator of its technological innovation output.
e new products sales revenue and patent applications of China's pharmaceutical manufacturing industry during 2012-2019 are demonstrated in Figure 3.  2.28 times, with an average annual growth rate of 12.49%. It shows that, with the continuous improvement of the R&D input of China's pharmaceutical manufacturing industry, the economic benefits have gradually improved. e number of patent applications in China's pharmaceutical manufacturing industry showed a fluctuating growth trend, from 14976 in 2012 to 23400 in 2019, an increase of 1.56 times. ere was only a short-term downward trend in 2015 and continued growth in the rest of the year. It shows that while China's pharmaceutical manufacturing industry attaches importance to drug R&D and innovation, its awareness of patent protection is also increasing. Under the combined action of demand growth, technological innovation, policy encouragement, talent gathering, and capital input, China's pharmaceutical manufacturing industry will be in a golden development period for some time in the future, showing a pattern of scale expansion, innovation upgrading, and competition differentiation [14,15].

Method.
is paper uses the data envelopment analysis (DEA) method proposed by Charnes et al. [16] to evaluate the technological innovation efficiency of China's pharmaceutical manufacturing industry. e evaluation methods of innovation efficiency mainly include the parametric method and nonparametric method.
Since the allocation of innovative resources is a complex system with multiple inputs and multiple outputs, compared with the parametric method, the nonparametric method does not need to estimate the parameters in advance, which is more in line with the multiple optimization criteria. DEA is representative of nonparametric methods, and it is also an effective method commonly used to evaluate the efficiency of technological innovation. It does not require model parameters, only multiple input and output data to calculate the effective frontier and then calculate the distance between each decision-making unit (DMU) and the effective frontier, thereby evaluating the relative effectiveness of each DMU.
DEA  [17] under input orientation is as follows: In model (1), j � 1, 2, . . . , n; i � 1, 2, . . . , m; r � 1, 2, . . . , s. n is the number of DMUs (years in our case); m and s are the number of input and output variables. x ij and y rj are input and output variables. s − and s + are the slack variables of input and output. θ is the effective value; ε is the non-Archimedean infinitesimal. When θ is 1, it means that the DMU is relatively efficiency, and when it is less than 1, it is inefficiency.

Research Sample.
Technological innovation is a multiinput and multi-output economic process. In the process of efficiency evaluation, choosing appropriate input and output indicators is crucial to the effectiveness of the evaluation results. e innovation input of the pharmaceutical manufacturing industry mainly includes capital and personnel input. Four input indicators are selected for the efficiency model: internal expenditure of R&D, external expenditure of R&D, new products development expenditure, and full-time equivalent on R&D personnel. e internal expenditure of R&D refers to the expenditure of a company to independently research and develop a specific technology, which promotes the internal generation of new knowledge and can promote various innovative activities [18]. External R&D expenditures are expenditures in the process of joint R&D activities carried out by enterprises and partners. is model is conducive to speeding up the R&D process of new technologies and knowledge [19]. New product development expenditures reflect the expenditures in a series of processes, including product, process design, production, and market expansion. e full-time equivalent on R&D personnel is a more accurate reflection of the workforce input in technological innovation. e outputs included in the analysis are as follows: sales revenue of new products and number of patent applications, reflecting the economic output and knowledge output of technological innovation activities. e definition of input and output variables is shown in Table 1. e data used for efficiency analysis comes from the "China High-Tech Industry Statistical Yearbook" and "China Science and Technology Statistical Yearbook." Given the availability of data, this paper selects the relevant data of China's pharmaceutical manufacturing industry from 2005 to 2019 and uses DEAP2.1 software to analyze the efficiency of technological innovation. Due to the hysteresis of innovation activities, the year's input cannot be converted into output immediately. erefore, this paper draws on Furman's method and sets the lag period to two years [20]. e input indicator is the 2005-2017 data, and the output indicator is the 2007-2019 data. Each year is regarded as the DMUs, and the relevant data is shown in Table 2.

Correlation Tests of Innovation Indicators.
Before measuring the technological innovation efficiency of China's pharmaceutical manufacturing industry, the Pearson correlation test should be performed on the input and output indicators. e results are shown in Table 3. e test results show that the correlation coefficient between innovation input and output indicators is more significant than 0.8 at the level of 1%, which has a strong correlation. erefore, the innovation input and output indicators selected in this paper are more reasonable, further measuring and analyzing technological innovation efficiency.

Technological Innovation Efficiency of China's Pharmaceutical
Manufacturing Industry. Table 4  Journal of Healthcare Engineering generation of information technology. As one of the hightech industries, the pharmaceutical manufacturing industry has gradually improved its intelligence level to maintain competitiveness. e automation and information construction level of China's pharmaceutical manufacturing industry is relatively low compared with other industries. After evaluating the innovation efficiency of China's pharmaceutical manufacturing industry, the overall innovation efficiency level was low, and it was in a low-efficiency state in most years. Strategies such as Industry 4.0 and the Industrial Internet have put pharmaceutical manufacturing corporates in the midst of information transformation. Pursuing the corporate sustainable development model, enhancing the corporate information application and management levels, and achieving smart manufacturing are crucial subjects of the pharmaceutical manufacturing industry [21]. Pharmaceutical smart manufacturing and Pharmaceutical Industry 4.0 can monitor all the pharmaceutical manufacturing and circulation processes in real-time online, effectively improving R&D and production efficiency. Moreover, data can be generated and read automatically and stored in the cloud directly, with zero delays and no blind spots [22]. A complete pharmaceutical smart manufacturing system comprises four layers: the equipment layer, the control layer, the business management layer, and the operating management layer. e system architecture is demonstrated in Figure 5 [23][24][25].
e equipment layer is usually composed of single hardware such as automated operating equipment, meters, and sensors. It is responsible for specific production tasks, providing underlying data support for production process control. e equipment layer can configure equipment that meets the requirements according to the corporate business scope and management needs. e control layer docks with the equipment layer, which is responsible for collecting and integrating data about the equipment layer. Hence, it is the basis of information management for smart manufacturing [26]. Corporates can achieve preliminary visual management through data integration in the control layer and further optimize the digital function structure and information flow structure. e business management layer can achieve the integrated application of business management in the smart manufacturing industry. People, machines, and materials can be fully integrated by optimizing and reconstructing the business management layer. e business management layer is connected to the operating management layer. As the transmitter of corporate management decisions, it is a key link to constructing the smart manufacturing system. e operating management layer straddles other systems and runs through the entire process of research, development, production, quality control, and logistics. It is the core for pharmaceutical manufacturing corporates to meet the management requirements of global optimization. An important prerequisite for the operating management layer to play the role of intelligent decision-making is the interconnection among the business management layer, the control layer, and the equipment layer. Important information can be visually displayed through data analysis to assist decision-making. e software system in the operating management layer helps the pharmaceutical manufacturing corporate realize top-down centralized management.

Smart Digital Transformation Path for China's Pharmaceutical Manufacturing Industry.
In the broad concept of medical and health, pharmaceutical is the backbone of the medical and health ecosystem. e pharmaceutical industry must follow the trend, fit the trend of digital development, actively seek new mutations, and better contribute to the advancement of the medical and health  with a market growth rate of about 10%. However, the overall digitalization degree is relatively low. Figure 6 shows the market scale and digital transformation trend of China's pharmaceutical. erefore, the long-term highspeed industry growth rate and the low digitization at this stage are both an opportunity and a challenge for the pharmaceutical industry digitization.
In the context of structural adjustment and overall upgrading of the pharmaceutical industry, pharmaceutical companies have gradually realized the importance of building a digital system. e current application of digital technology in pharmaceutical companies has four paths from a value perspective. e first path is enabling scientific research. New drug research and development is the beginning of the entire drug life cycle. rough digital empowerment, the storage, integration, feedback, management, and in-depth mining of a large number of preclinical and clinical trial research data can reduce R&D costs, speed up the development process, and improve the success rate of research and development [28]. e second path is improving the quality of medicines. Compared with other industries, the pharmaceutical industry has stricter requirements on product quality, and the stability of drug quality is the foundation of its market value.
e application of quality digitization is conducive to ensuring the quality of drugs and is also the key to the entire life cycle of drugs. It is mainly used in process design, production process monitoring, and drug batch evaluation [29]. rough quality digital technology, it is possible to track and monitor whether the wholeprocess meets the quality specifications, minimize the influence of human factors, strengthen the standardization of the process, and continuously improve the quality of medicines. e third path is optimizing the production process. e use of digital technology can monitor the status and potential risks of production equipment in real-time, reduce nonproduction use time, and effectively avoid risks. It can also make scientific decisions based on visual data analysis for production scheduling and storage of production materials to improve production efficiency. e fourth path is reorganizing business operations. Standard reports and accumulations produced by digital technology can provide valuable data for business operators and improve business efficiency. e massive data analysis provides scientific and effective decision-making for operation management personnel based on indicators such as cost, workforce, and procurement. It also feeds back information such as business performance and risks to business managers in real-time,    Journal of Healthcare Engineering 7 enhances business decision-making capabilities, and optimizes business development directions and models [30].   on the full use of new technologies, comprehensively carry out intelligent upgrades and digital transformations, and further improve innovation efficiency. e research results are of great value in clarifying the current state of technological innovation in China's pharmaceutical manufacturing industry and the direction of upgrading the pharmaceutical smart manufacturing industry.

Future Research.
In the context of the rapid development of a new generation of information technology, the pharmaceutical manufacturing industry has huge technological innovation potential. e pharmaceutical smart manufacturing industry can reduce R&D costs, ensure the quality of medicines, and improve efficiency. After evaluating the innovation efficiency of China's pharmaceutical manufacturing industry, it was found that the efficiency of resource allocation is low. It proposes the direction of industrial upgrading and digital transformation from a theoretical level and provides new ideas for the intelligent upgrade of the pharmaceutical manufacturing industry. However, the impact of new technologies on the intelligent upgrade of the pharmaceutical manufacturing industry has not yet been quantitatively studied. erefore, in future research, empirical analysis can be carried out by collecting indicator data to reflect the level of new technologies and intelligent upgrades to make the impact mechanism clearer.
