Study on the Spatio-Temporal Characteristics and Spatial Correlation of Coupling Coordination Degree between Petrochemical Industry Chain and Innovation Chain
Based on the data of 30 provinces(municipalities and districts)in China from 2012 to 2022,the comprehensive development index of the petrochemical industry chain and innovation chain was calculated,and the coupling coordination degree model was constructed for analysis.The results show that the comprehen-sive development index of the two chains increases year by year,but the overall level is low;The degree of cou-pling coordination fluctuates,the overall level is low;and the east,central and west are decreasing in turn,Zhe-jiang is leading,and most provinces are maladjusted;The coupling coordination degree has a significant spatial positive correlation,showing high-high and low-low agglomeration characteristics;The correlation between multiple indexes of the two-chain system and the coupling coordination degree is above 0.45,which belongs to the medium correlation.It is suggested to propel the deep integration of the"double chains"of the petro-chemical industry,promote regional coordinated development,and push forward the digitalization and greening of the petrochemical industry.
