摘要
我国能源空间结构呈现东缺西余的分布格局,客观上需要在东西部之间实现电力的空间再配置,这对不同地区将产生差异性的增长效应。西电东送工程形成了北、中、南三路输电通道,对不同区域的经济增长产生什么样的促进作用?本文利用1994—2019年中国283个地级及以上城市面板数据,在理论机制分析的基础上,通过设计多期双重差分模型对西电东送政策的地区经济增长效应及差异的实证分析。研究发现,西电东送工程促进了电力输送两端地区的经济增长;同时,西电东送对输入地的促进作用明显大于输出地,且对不同通道涉及地区的经济增长具有明显差异。因此,本文建议在新发展格局下继续推进西电东送工程实施支持电力输入地经济稳定发展的同时,进一步推进电力市场改革,形成合理的电力定价机制,保证电力输出地区能够获取较多电力输送的经济效益。
China’s energy spatial structure presents a pattern of distribution that is rich in the west and scarce in the east,and objectively it is necessary to realize the spatial reallocation of electricity between the east and the west,which will have a different growth effect on different regions.The West-to-East Power Transmission Project implemented in China has formed a three-way transmission channel in the north,central and south.What kind of contribution will it have for economic growth in different regions?This is a question that requires in-depth study,but relevant research is relatively lacking.Based on the analysis of theoretical mechanisms,this paper uses panel data from 283 cities in China from 1994 to 2019 to design a multi-period Difference-in-Differences model,the regional economic growth effect and its difference of the West-to-East power transmission policy are empirically analyzed.The study found that the West-to-East Power Transmission Project promoted the economic growth of the two ends of the power transmission,and at the same time,the promotion effect of the West-to-East Power Transmission on the input area was significantly greater than that of the output area,and the economic growth effect of the areas involved in different channels was obviously different.Therefore,this paper proposes to continue to promote the implementation of the West-to-East Power Transmission Project under the new development pattern to support the stable development of the economy of the power importing areas,and further promote the reform of the electricity market,rationalize the power pricing mechanism,and ensure the power exporting areas can obtain more economic benefits from power transmission.
