长三角城市群工业生态效率空间溢出效应及其影响因素

工业生态效率能够反映经济发展、环境保护和资源节约之间的平衡关系，探究工业生态效率对于转变工业发展方式，实现可持续发展具有重要意义。该文测算长三角城市群工业生态效率，并对其时空演变、区域差异、溢出效应及影响因素的空间效应进行探索。研究发现：长三角城市群工业生态效率均值不断上升，绝对差异增加，而相对差异变化不大；具有正的空间相关性，在空间分布上具有一定的集聚性；呈现出“东高西低”的空间特征，具有显著的高-高和低-低集聚的空间俱乐部分布特征；在工业生态效率类型转移过程中存在着趋同的趋势，并且具有显著的空间溢出效应；科技投入和经济发展对本地工业生态效率的提升起显著的推动作用，而工业结构不利于本地工业生态效率的改善；本地城镇化的提升不利于邻近其它城市工业生态效率的提升；而本地科技投入和经济发展有利于邻近其它城市工业生态效率的提升。加强城市之间合作对提升工业生态效率具有重要影响。

Spatial Spillover Effects and Driving Factors of Industrial Eco-efficiency in Yangtze River Delta Urban Agglomerations

Industrial eco-efficiency can reflect the relationship among economic development, environmental protection and resource conservation, so it is of great significance to explore the industrial ecological efficiency in Yangtze River Delta Urban Agglomerations. This paper firstly calculated the industrial eco-efficiency, and then explored the spatial and temporal evolution, regional differences, spillover effects and influencing factors. Some conclusions were drawn as follows. Over 2012-2016, both the average industrial eco-efficiency and absolute difference showed increasing trend, while the change in relative difference was little. The industrial eco-efficiency showed positive spatial correlation and high-eco-efficiency ‘club’ agglomeration. The industrial eco-efficiency of eastern regions was higher. It also presented an obvious spatial spillover effect. Besides, the evolution of the industrial eco-efficiency had the characteristic of obvious path dependence. The influence of industrial structure, scientific and technological input and economic development on industrial eco-efficiency was obvious. Investment in science and technology and economic development playen a significant role in promoting the local industrial eco-efficiency, while the industrial structure was not conducive to the improvement of local industrial eco-efficiency. The improvement of local urbanization was not conducive to the improvement of industrial eco-efficiency for neighboring cities. The local investment in science and technology and economic development were conducive to the improvement of industrial ecological efficiency for neighboring cities. Strengthening cooperation among cities had an important impact on improving industrial eco-efficiency.
