【摘要】：基于长江经济带108个城市2003-2014年数据,分别测算了长江经济带城市产业升级、生态环境优化和产业升级与生态环境优化耦合协调度指数,在此基础上,采用系统广义矩估计方法实证研究了产业升级与生态环境优化耦合度的影响因素,研究表明:样本期间内长江流域城市产业升级综合得分显著低于生态环境优化综合得分,长江经济带城市属于产业升级滞后型;长江外围城市耦合度明显高于沿江城市,且纵向来看下游城市产业升级和生态环境优化耦合协调度不断提高,而中上游城市却有所降低;对产业生态耦合协调度影响因素的进一步研究发现,经济增长、研究与开发、制度质量是实现产业与环境优化发展的重要因素,而产业结构、固定资产投资和外商直接投资降低了产业升级与生态环境优化耦合度,从全球产业链低端向产业链高端跃升、经济增长、制度优化是提高产业与环境耦合发展的关键。
[Abstract]:Based on the data of 108 cities in the Yangtze River Economic Belt from 2003 to 2014, the paper calculates the index of industrial upgrading, ecological environment optimization and coupling coordination between industrial upgrading and ecological environment optimization. The paper empirically studies the influencing factors of the coupling degree between industrial upgrading and ecological environment optimization by using the method of system generalized moment estimation. The results show that the comprehensive score of urban industrial upgrading in the Yangtze River basin is significantly lower than that of ecological environment optimization in the sample period. The cities in the Yangtze River economic belt belong to the backward type of industrial upgrading, the coupling degree of the peripheral cities of the Yangtze River is obviously higher than that of the cities along the Yangtze River, and the degree of coupling and coordination between the industrial upgrading and the ecological environment optimization in the downstream cities is increasing continuously, while the cities in the upper reaches of the Yangtze River have been reduced. Further research on the factors affecting the degree of industrial ecological coupling and coordination reveals that economic growth, research and development, and institutional quality are important factors to realize the optimal development of industry and environment, while the industrial structure, Fixed assets investment and foreign direct investment (FDI) reduce the coupling degree between industrial upgrading and ecological environment optimization, and jump from the low end of the global industrial chain to the high end of the industrial chain. Economic growth and system optimization are the key to improve the coupling development of industry and environment.
