Modernization of China's Industrial Chain:Level Measurement,Regional Gap,and Influencing Factors
Promoting the modernization of the industrial chain is an important part of building a new development pattern.At present,the global industrial chain shows a restructuring trend of"vertical shortening and horizontal regional agglomeration",and the security and stability of China's industrial chain is facing major challenges,so upgrading the modernisation level of the industrial chain is an important measure and an inevitable requirement for ensuring the healthy development of China's economy.Scientific measurement of the modernization level of China's industrial chain,exploration of its spatial imbalance characteristics,and in-depth analysis of the causes of regional differences are of great significance for promoting the coordinated improvement of the modernization level of inter regional industrial chains.Using a combination of subjective and objective measurement methods to measure the modernization level of China's industrial chain from 2011 to 2020,using Dagum Gini coefficient and Kernel density estimation methods to reveal the relative and absolute differences in the modernization level of the industrial chain,and using QAP method to explore the causes of its spatial imbalance.The study finds that:during the inspection period,the modernization level of the industry chain of the four major sectors rises,generally showing a development pattern of East>Central>West>Northeast.Continuous improvement in industrial foundation advancement,industry chain R&D autonomy,industry chain synergy and industry chain sustainability.The relative gap in the level of modernization of the industry chain among the four major segments is significant and on the rise during the study period,with the difference between the eastern region and the other three regions being the main component of interregional differences.Opening up to the outside world,economic development,transportation infrastructure and government regulation all have a significant impact on the regional differences in the level of regional industrial chain modernization,in which opening up to the outside world is an important focus and growth point for the coordinated development of China's industrial chain modernization to a high level.
