视角下能源消费对经济增长的影响研究——基于长江经济带沿线城市的动态面板数据分析

The Impact of Energy Consumption on Economic Growth in the Context of Opening: an Empirical Analysis on the Dynamic Panel Data of Cities along the Yangtze River Economic Belt

基于长江经济带沿线城市2000-2014年的面板数据,分析开放经济背景下能源消费对经济增长的动态影响及其作用机制;同时比较其在长江三角洲城市群、长江中游城市群和成渝城市群直接差异发现:能源消费和对外开放均是推动长江经济带经济增长的重要因素,且能源消费对经济增长的促进作用在长江中游城市群最大,成渝城市群次之,长三角城市群的影响最小。对外贸易和FDI对经济增长的直接作用在长三角城市群显著,在长江中游城市群和成渝城市群中则不显著;对外贸易通过提高能源效率间接促进经济增长的效应也只在开放程度相对较高的长三角城市群显著。

This paper analyses the dynamic effect and mechanism of energy consumption on economic growth in the context of open economy by using the panel data of cities along The Yangtze River Economic Belt over 2000-2014. Moreover, this paper compares the differences among three subsamples, Yangtze River Delta, middle reaches of the Yangtze River and Chengdu-Chongqing City agglomeration. We find that, both energy consumption and open economic variables are important factors to promote the growth of economy in the Yangtze River economic belt, and the positive effects of energy consumption impact on economic growth is the largest in the middle reaches of the Yangtze River, followed by the Chengdu-Chongqing City agglomeration and the Yangtze River. The direct effect of trade and FDI on economic growth are more significant in Yangtze River Delta than the others; moreover. We also find that international trade spur economic growth indirectly by improving the efficiency of energy only in Yangtze River Delta.
