  • With the development of science and technology, digital economy has penetrated into traditional manufacturing industry extensively and deeply, which has motivated the progress of the digital transformation for traditional manufacturing industry. Through comparative analysis of theoretical mechanism of synergetic development, this paper researches the order degree model and the synergy degree model based on the social shaping of technology theory to evaluate the synergetic degree of the digital transformation for China's traditional manufacturing industry. An empirical study is presented based on the proposed models and the spatial analysis method by using the statistical data of Yangtze River Delta in China from 2014 to 2019.

    With the intensification of a new round of industrial competition in the global economy and the strategy of "Made in China 2025", the digital economy has been integrated into all areas of society and become the new driving force for transformation of traditional manufacturing industry [1]. The digital economy can optimize the way of resource allocation, and further stimulate the coupling effect and dual-wheel driving role of the market and the government in resource allocation. The digital transformation of traditional manufacturing industry, as complex systems, the involves many diverse factors. Digital transformation is not just digitization, but digitization plays a significant role in it, which will create some demand for the digital industry and the manufacturing organization's IT department. In the process of digital transformation, China's traditional manufacturing enterprises need to change the original value creation mode, seek cross-boundary partners from a larger value network, and transform from focusing on their own interests to focusing on the value maximization of the entire network [2], which can overcome the double resistances that the manufacturing reflux in the developed countries and the rapid development of emerging economies manufacturing in the world [3]. If the efforts from digital industry are not adapted to the key structure of manufacturing industry, digital technology is difficult to play its important role in manufacturing industry transformation and upgrading, which leads to the "IT paradox" [4]. The coordination between regional economic, social development and digital industry are the key factor for the digital transformation of traditional manufacturing industry. This paper research how to coordinate various factors based on the synergistic theoretical framework and proposed the upgrading mechanism of China's traditional manufacturing industry driven by digital economy.

    In order to effectively measure the digital transformation situation, this paper proposes the synergetic theory and the entropy weighting method to study and measure the order degree and synergy degree of China's traditional manufacturing digitalization transformation system, which the synergy model is constructed from the perspectives of technology subsystem, industrial subsystem and economic subsystem based on the synergistic theory. The main research contribution of this paper are as follows. First, an order parameter system of the digital transformation synergy system is developed based on the social shaping of technology theory, after that a quantitative analysis model is established based synergetic theory. The subsystem order degree and composite system synergy degree are analyzed to study the digital transformation efficiency of China's traditional manufacturing industry within the system according to the statistical data of Yangtze River Delta in China from 2013 to 2019.

    The digital economy refers to a broad range of economic activities that use digitized information and knowledge as key factors of production. The internet, cloud computing, big data, Fintech, and other new digital technologies are used to collect, store, analyze, and share information digitally and transform social interactions. Digital transformation is an important approach to the digital economy society. The digital transformation of traditional manufacturing industry creates benefits and efficiencies as digital technologies drive innovation and fuel job opportunities and economic growth. Many studies have focused on digitized process with the aim of finding solutions to deep integration of IT technology and society so as to provide new development paths, which can be summarized from three perspectives:

    1) Analyses of the changes brought about by the digital economy. Bojnec, Ferto investigated the impact of the number of Internet users on the bilateral manufacturing export growth among OECD countries based on the gravity model using panel and cross-section regressions, which the empirical results suggest that the Internet stimulates manufacturing export [5]. Huang discovered several bottleneck problems of China's manufacturing from a big towards a power in the world, and put forward four development directions such as the re-factoring the basic producing ability of IE, cultivating the lean management innovation power, optimizing the industrial structure and promoting its value chain upgrade [6]. Gaputo, et al. proposed that Industry 4.0. connected everything and Internet of Things technology have become important driving forces for the digital transformation of manufacturing industry [7]. Zeng, et al. proposed that digital transformation is a process that starts from the infrastructure of digital technology, digital products and digital platform, and then leads to changes in individual, organizational, industrial and other levels [8].

    2) Construction of digital transformation measurement indices. Wang analyzed the active influence of Internet plus on Chinese enterprise productivity based on the survey data of the world bank [9]. The empirical results show that actively promote manufacturing Internet plus should take different measures and modes according to the different industries and regions. The digital transformation of traditional manufacturing industry, as a dynamic, open and complex system included political, social organizational, cultural factors and so on. It is, rather, a social product defined by the external conditions that create and use it. However, there are few researches evaluate the digital transformation of traditional manufacturing enterprises from the social and economic factors as well as technical considerations. In contrast to technical determinism, the social shaping of technology (SST) theory is a new perspective in which technology is not viewed as developing by its own inherent logic [10]. The SST theory has developed as a response to techno-economically rational and linear conceptions of technology development and its consequences, which examines the content of technology and the processes involved in innovation [11]. The SST theory emphasizes the mutual connections between technology and society and avoids the unilateralism and extremity in the technological determinism and the social determinism, and so it is more close to the external instance between technology and society [12].

    3) Digital transformation development measures. Yan used the benevolent DEA cross efficiency model to evaluate the integration efficiency between high-tech industry and traditional industry of urban agglomeration during the period of 2001–2013, which put forward some policies to promote the integration development of the middle reaches of Yangtze River [13]. Tan employed the GMM model to analyze the impact informatization upgrading mechanism of manufacturing industry based on the panel data from 283 cities of China during 2004–2014 year, the empirical results show that urban informatization will promote upgrading of the manufacturing industry [14]. Haken applied the synergy theory to study the self-organization of unstable open system by its own coordination mechanism under the external energy and material exchange [15]. Xie conducted a multi-case study to explore strategic risk identification and control mechanisms of Internet-oriented transformation for the traditional enterprises based on the synergistic degree model [16].

    This paper investigates the industrial digital transformation mechanism based on SST, expounding the digital economy influence on traditional manufacturing industry from its essence, characteristics, functions, values to development. Combined with the synergetic theory and entropy weighted method, the synergy degree model was used to study the order degree of all subsystems and the synergetic degree model of the digital transformation for traditional manufacturing industry from the aspects of technology, industry and economy subsystems. in order to reveal the digital transformation mechanism of China's traditional manufacturing industry.

    Digital transformation is the innovation process form the multiple levels of the individual, organization and industry supported by the infrastructure of digital technology, digital product and digital platform, which digital transformation has impacted the development path, organizational model and national strategy [17]. The collaborative mechanism of the system is analyzed under the view of order parameter. The order degree model defines the order parameter and investigates the internal coordination of the affecting subsystems, which the co-evolution state of integrated system is controlled by the order parameter [18].

    The construction of an effective synergistic measurement index system is essential to accurately assess the synergy degree, which means that appropriate order parameters need to be identified and selected for each subsystem. According to synergy theory, variables that determine the system are called order parameters. The order parameter is generated by each single subsystem, which in turn dominates the behavior of each subsystem, reflecting the evolutionary trend of subsystems and composite system. The relationship diagram of digital transformation for traditional manufacturing industry based on the SST are constructed and shown in Figure 1.

    Figure 1.  The digital-transformation of manufacturing industry based on SST.

    Based on the inter-relationship analysis in Figure 1 and the "China Statistical Yearbook" from the national bureau of statistics over the years, the proper order parameters were selected and the order parameter system for the manufacturing industry digital transformation from the collaborative subsystem of technology, economy and manufacturing industry is constructed and shown in Table 1.

    The detailed approaches and Eqs (1)–(7) about the synergy degree measurement model by entropy weighting method for the digital transformation of traditional manufacturing industry are as following:

    1) The order degree of order parameter Xij

    The collaborative development of digital economy enabling traditional manufacturing industry is regarded as the composite system S composed by multiple collaborative subsystems, S = (S1, S2, …, Sk).

    The composite system of technology, industry and economy subsystem is set to be S = {S1, S2, S3}, where S1 is the technology subsystem, S2 is the industry subsystem, and S3 is the economy subsystem. The order parameter Xij (Xi1, Xi2, …, Xim) of the subsystem represents the state variable of the order parameter in the subsystem. where m 1, Xmin ≤ Xij ≤ Xmax, j = 1, 2, …, m. Let Xmax and Xmin be the upper and lower limits of the order parameter component Xij at the system stability critical point respectively.

    In the order parameters {Xi1, Xi2, …, Xim} as positive index, the larger value of order parameter indicates, the greater the effect of Xij on the ordering degree of the subsystem. The other order parameters {Xi(m+1), …, Xin}as negative index, the larger value indicates the lower the effect of Xij on the ordering degree of the subsystem. The Eq (1) of order degree of the order parameter Xij in the subsystem Xi is expressed as:

    Ui(Xij)={XijXminXmaxXminj=1,2,,mwhere Xij is a positive indicatorXmaxXijXmaxXminj=m+1,m+2,,where   Xij   is a negative indicator  (1)

    From Eq (1) represent the effect of order parameter on the subsystem, 0 ≤ Ui(Xij) ≤ 1, which the larger value of the Ui(Xij) reflect that Xij has greater influence for the Xi subsystem.

    2) The synergy degree of the Si subsystem

    This paper to calculates the order degree of collaborative system Xi for digital economy enabling traditional manufacturing industry by linear weighted sum method. The order degree of subsystem Xi can be expressed by the state of order parameters Xij, which can be obtained by the Eq (2).

    Ui(Xi)=ni=1λjUi(Xij) (2)

    where λj is the weight of Xij in the subsystem and reflects the importance of the component Xij in maintaining the ordering degree of system, λj0,ni=1λj=1.

    3) The synergy degree of the composite system

    In order to calculate the order model of coordinated system for the digital industry enabled traditional manufacturing industry, this paper set the order parameter of each subsystem is U0i(Xi) (i = 1, 2, 3) at the assumed starting time t0 time, U01(X1) represents the ordering degree of the technology subsystem, U02(X2) represents the ordering degree of the industry subsystem, and U03(X3) represents the ordering degree of the economy subsystem.. After development t1 time, the order parameter of each subsystem becomes U1i(Xi) (i = 1, 2, 3). The definition of the order parameter for the composite system from the t0 ~ t1 period is as following:

    C=θ×mmi=1|[U1i(Xi)U0i(Xi)]| (3)

    where

    θ={1   U1i(Xi)U0i(Xi)>01   others (4)

    From Eqs (3) and (4), The synergy degree of the composite system C[-1, 1] is actually a state where two subsystems forming the composite system can cooperate and develop. The greater the C, the greater the synergy effect of the composite system, and vice versa. Therefore, the synergy degree of system within C[-1, 0] can be inferred at the non-cooperative state. If U1i(Xi)U0i(Xi)>0, then the complex system of traditional manufacturing and digital industry evolves synergistically, else the subsystem does not develop at the coordinative direction.

    4) Determination of indicator weights by entropy weighting method

    Step 1: Assuming that the proportion of the i-th plan under the index j is

    cij=Ui(Xij)ni=1Ui(Xij) (5)

    Considering that the order parameters has positive and negative directions, and the entropy method handles the positive and negative indexes in the same way as the Eq (1), so the order degree is used for calculation cij in Eq (5). Calculating the entropy value of the j-th index byHj=1lnnni=1cijlncij, if cij = 0, then cij*lncij = 0.

    Step 2: For the j-th index, the greater the difference between the indexes, the greater the effect on the solution evaluation, and the corresponding entropy value is naturally low. Calculate the utility value of index j-th:

    dj=1Hj (6)

    Step 3: Calculating the weight of index j-th by

    λj=djnjdj (7)

    where λj is the weight of j-th index.

    To sum up the detailed calculation steps, the synergy degree measurement model of digital economy enabling traditional manufacturing industry is shown in Figure 2.

    Figure 2.  The synergy degree measurement model of digital transformation.

    According to the established synergy degree model and order parameter system, this paper research the synergy development degree of digital Transformation for traditional manufacturing industry from the technology, industry and economy subsystem in the Yangtze River Delta of China. The order parameter normalization and the entropy value were calculated by using Stata software to find order parameters information quantity and weights for the digital transformation system.

    From Table 7, the synergy coefficient of the industrial-digital ecosystem in the Yangtze River Delta has mostly positive values within [-0.1, 0.1]. The integration of traditional manufacturing and digital industries in Jiangsu Province and Zhejiang Province has the higher quality development, which show steady growth the overall rising from 2014 to 2019. Specifically, Anhui Province reached a negative value in 2015 and 2017, but in the following year, negative positive and substantial growth, indicating that Anhui Province has great development vitality. The spatial analysis results by using the statistical data as Figure 4 show that: The coordination degrees of traditional manufacturing industry integrated with digital industry in the Yangtze River Delta of China are increasing, but the synergy effect of social subsystem and technology subsystem aren't obvious due to the industry isomorphic, lack of digital literacy or digital-socioeconomic barriers.

    Figure 4.  The spatial distribution of synergy degree in the Yangtze River Delta.

    Such obstacles have diminished dramatically with IoT services and EI 4.0 solutions, which has effectively increased the value-added value of China's traditional manufacturing industry. With the application of AI and the Industrial Internet, it realizes the data sharing in productivity and production mode. Industrial Internet applications grant free access to enterprise data, which has redefined the life cycle of manufactured products. Through data sharing, the status monitoring, efficiency analysis, remote diagnosis and history tracing of the production site can be realized. In the age of digital economy, it is urgent for manufacturing enterprises to develop industrial internet and promote intelligent manufacturing, which they can bridge the physical-digital divide with the platform of Internet of things and make the China's manufacturing industry from big to power.

    Through analysis of synergetic development theoretical mechanism, this paper researches the order degree model and the synergy degree model based on the social shaping of technology theory to evaluate the synergetic degree of digital industry and traditional manufacturing industry of China. Combined with the Entropy weighted method, the synergy degree model was used to study the order degree of all subsystems and the synergetic degree of the composite system. From this study, the digital transformation mechanisms of China's traditional manufacturing industry are mainly reflected in the following aspects:

    1) China's government should lunch many new policies under the digital economy to reconstruct the value chain of traditional manufacturing industry, such as increase innovation investment, improve the transformation efficiency of the scientific and technological achievements and. The government can alleviate the innovation burden of enterprises by means of gradient tax cuts and fee reductions in order to encourage regional leading enterprises build a cross-border industrial chain system by supporting the adoption and enforcement of relevant laws and regulations.

    2) With the China's super-large market, the traditional manufacturing industry should treat the digital resources as its primary factor of production, and digital technologies of Industrial Internet Consortium (IIC), cloud computing and artificial intelligence as its main driving force. The traditional manufacturing enterprises should build a digital economy industrial ecosystem and support the breakthrough of new frontier technologies by the mode of industry-institution cooperation with the universities, scientific research units and other important market players in a rational and orderly manner in order to reducing the digital divides.

    3) China's manufacturing industry should deepen the integration with digital economy and solve the industries' "pain points" by digital infrastructure construction, digital market development and human capital cultivation. IT enterprises have rich digital experience and technical advantages of shorten the time cost in talent training and scientific innovation for traditional manufacturing enterprises. At the same time, the traditional manufacturing industry can apply digital technology of Industry 4.0 to improve the quality of product and increase the competitiveness in the market.
