工业互联网平台对产业融合影响的实证研究

工业互联网是推进我国经济高质量发展的重要引擎，是制造业转型升级的加速器。工业互联网平台已成为一种新的经济业态和服务载体，并渗透到产业与企业各个层面，深刻影响着制造业产业融合水平。基于2013-2019年省级面板数据，运用面板分位数回归法，分析工业互联网视角下平台经济发展水平与产业融合的关系，揭示工业互联网平台发展水平对产业融合的作用机理，检验制造业升级对平台经济发展水平与产业融合的中介效应。结果表明，工业互联网平台发展对技术融合与生产性服务业和制造业融合的影响不显著，对供应链与价值链融合有显著正向影响。进一步分析发现，制造业升级在工业互联网平台对供应链与价值链融合的影响中具有完全中介效应。研究结果对揭示工业互联网平台、制造业升级和产业融合三者间关系，推动工业互联网平台赋能制造业融合发展具有重要意义。

Empirical Research of on the Influence of Industrial Internet Platform on Industrial Integration

In the era of Industrial Internet, platform economy has become a new economic form and service carrier deeply influencing all the development level of primary, secondary and tertiary industries. The industrial Internet platform, as the deep integration of information technology and industrial modernization, effectively link up industry chain, supply chain, value chain upstream and downstream market players, and thus it promotes the expansion and penetration of platform economy. Then will the development level of platform economy affect industrial integration? What are the influence mechanism and realization path? In view of this, this study focuses on the impact of the platform economy and industrial convergence from the perspective of the industrial internet, and proposes that the development of industrial internet will promote the industrial convergence through three mechanisms: technology convergence, producer services and manufacturing integration, and supply chain value chain integration. On the basis of the provincial panel data from 2013 to 2019, this study uses the panel quantile regression method to analyze the relationship between the level of platform economic development and industrial convergence from the perspective of Industrial Internet. It reveals the effect mechanism of industrial internet platform development level on industrial convergence, and tests the intermediary effect of industrial upgrading on platform economic development level and industrial convergence. The results show that the development of industrial internet platform has no significant impact on the integration of technology and producer services and manufacturing, but it has significant positive impact on the integration of supply chain value chain. Further analysis shows that the industrial upgrading of manufacturing industry has completely mediating effect on the integration of supply chain and value chain in the industrial internet platform. In view of the empirical results, this paper puts forward the following suggestions. First, the development of industrial Internet platform should be further standardized so that the industrial Internet platform can play its due role in technology convergence. At present, the number of cloud enterprises in China is very small, one of the important reasons is that the level of industrial Internet governance is relatively low, not yet standardized. Hence it is necessary to issue relevant laws timely to further regulate the platform governance under the Industrial Internet, take disciplinary measures against monopoly giant industries, and create a healthy virtuous circle environment for the development of industrial Internet. Meanwhile the risk assessment and supervision of industrial Internet should be strengthened to perfect the legal system supporting the platform economy. Second, the integration of manufacturing and service industries based on industrial linkages should be strengthened. On the one hand, high-quality development of the service sector should be enabled based on industrial mode of production and Internet thinking. It is critical to strengthen the cultivation of key industrial sectors based on integrated applications, and focus on the standardization of industrial applications in producer services, form and promote industrial internet-based production production of specific scenarios and replicable production solutions. On the other hand, the technological advantages of industrial interconnection should be given full play to carry out technological empowerment. Manufacturing enterprises should be encouraged to have the digital transformation and stimulate the enthusiasm of producer services to make use of the platform to serve the manufacturing industry, promote the formation of industrial convergence. Third, the role of the industrial internet is attached with great importance in promoting the integration of value chains and provide targeted policy support. Not only the actual value-creating role of the producers of industrial internet links in the value chain should be stressed, but also the reasonable value demands of the builders of industrial Internet should be protected to avoid anyone taking advantage of its own previleges to participate in value predation.
