中国数字经济与制造业耦合协调关系:高质量发展视角

The Coupling and Coordination Relationship between Digital Economy and Manufacturing Industry in China:A High-quality Development Perspective

推动数字经济与制造业高质量耦合协调发展,是中国构建现代化产业体系和塑造国家竞争新优势的内在要求。基于2012—2022年中国30个省份的面板数据,在厘清数字经济与制造业高质量发展耦合协调机制的基础上,构建数字经济和制造业高质量发展的评价指标体系,运用熵权TOPSIS法对数字经济与制造业高质量发展水平及其各子系统发展水平进行测度,并采用耦合协调度模型研究两系统的耦合协调关系。研究表明:东部地区数字经济与制造业高质量发展的耦合度和耦合协调度相对较高,但中西部地区的上升趋势更为明显。从各子系统的耦合度来看,数字经济与市场需求的耦合度最高,与政府导向的耦合度最低;同时,与企业自身、行业发展和市场需求的耦合度存在较为明显的上升趋势。从各子系统的耦合协调度来看,数字经济与各子系统的耦合协调度等级大体趋同,但尚未达到良好的状态,有待进一步提升。这一结论也印证了耦合协调是耦合的高级阶段,有效促进各子系统与数字经济的耦合协调关系,才能提升数字经济与制造业高质量发展整体的耦合协调水平。

Promoting the high-quality coupling and coordinated development of the digital economy with the manufacturing industry is an inherent requirement for China to build a modern industrial system and shape new competitive advantages at a national level.Based on panel data from 30 provinces(including municipalities and autonomous regions)in China from 2012 to 2022,the index evaluation system of digital economy and high-quality development of manufacturing industry is constructed on the basis of clarifying the coupling and coordination mechanism of high-quality development of manufacturing industry and digital economy.The entropy weight TOPSIS method is used to measure the development levels of the digital economy and the manufacturing industry along with their subsystems.Additionally,a coupling coordination degree model is employed to examine the coupling and coordination relationship between these two systems.The results indicate that:firstly,the coupling degree and coordination degrees of the digital economy and high-quality development of the manufacturing industry in the eastern regions are relatively higher,but the upward trend in the central and western regions is more obvious.The main reason behind is that the digital economy and high-quality development level of the manufacturing industry in the eastern regions have the characteristics of“double high”,while the high-quality development level of the manufacturing industry in the underdeveloped areas of the central and western regions in the early stage is low,and the corresponding platform and technical support for the development of the digital economy have not been provided,but the development level of the digital economy in the central and western regions has been rapidly improved in recent years,providing a strong enabling role for the high-quality development of the manufacturing industry.Secondly,from the perspective of the coupling degree of each subsystem of digital economy and high-quality development of manufacturing industry,the coupling degree between digital economy and market demand is the highest,and the coupling degree between digital economy and government orientation is the lowest.At the same time,there is also a clear upward trend in the degree of coupling with the enterprises themselves,industry development and market demand.Thirdly,from the perspective of the coupling coordination degree of each subsystem of the digital economy and the high-quality development of the manufacturing industry,the coupling coordination degree level of the digital economy and each subsystem is generally convergent,but they have not yet reached a good state and need to be further improved.The conclusions also verify that,coordination is an advanced stage of coupling,and effective promotion of the coordination relationship between various subsystems and the digital economy is essential to enhance the overall coordination level of high-quality development between the digital economy and the manufacturing industry.Therefore,it is necessary to further promote the deep integration of digital technology and manufacturing industry,and promote the development of industrial digitization and digital industrialization;At the same time,establish an inter-regional cooperation and exchange mechanism to promote the cross-regional coupling and coordinated development of the digital economy and manufacturing industry;In addition,it is necessary to correctly understand the imbalance of the coordinated development of digital economy and manufacturing industry,and give full play to the interaction between government policies and market mechanisms in the high-quality development of digital economy and manufacturing industry,so as to effectively promote the high-quality coupling and coordinated development of China’s digital economy and manufacturing industry.
