基于空间面板模型的中国市场化与能源效率研究

Study on Relationship between China's Marketization and Energy Efficiency Based on Spatial Panel Data Model

中国市场化进程不断深入,市场化各个方面都对能源效率产生影响。本文旨在探求中国市场化进程与能源效率之间的空间关联机制。长期以来,经济学界假设空间是均质的,往往忽视空间异质性问题。事实上,中国区域范围内能源效率和市场化水平的空间集聚性和空间差异性非常显著。纳入空间效应建立空间面板计量经济学模型对中国市场化与能源效率的空间关联机制进行实证研究,结果发现:中国区域能源效率存在明显的空间集聚(空间自相关),中国市场化与能源效率存在较强的空间交互关联机制,地理邻近的省域通过空间溢出效应途径明显地改善邻近地区的能源效率。

In the context of the rapid development of China＇s marketization, energy efficiency is influenced by this process from all aspects. This paper aims at the exploration of spatial relationship between marketization and energy efficiency. The classical economic theory has long hypothesized that geographic space is homogeneous, but overlooked the nature of spatial heterogeneity. Actually, in China there is a geographically significant spatial cluster for energy efficiency and the degree of marketization over space. Taking spatial ef- fects into consideration in the model, spatial panel data technique is employed to analyze China＇s spatial relationship between marketization and energy efficiency empirically. The results indicate that regional energy efficiency of China has a significant spatial cluster （spatial autocorrelation） among provinces and there is a relatively positive spatial interactive mechanism between marketization and energy efficiency. The provinces apparently improve the energy efficiency of neighboring areas by means of spatial spillovers.
