基础设施的经济增长效应与能耗效应——以电网为例

Impact of Infrastructure on Regional Economic Growth and The Energy Consumption:An Empirical Analysis Regarding Power Grid

本文利用地区面板数据和基于利润函数,考察电网基础设施的能耗效应、产出效应及其地区差异。主要发现是,电网基础设施的发展促进了地区经济增长,增加了地区能源消费,其能耗效应和产出效应有显著的地区差异。在西部地区,电网设施的经济增长效应明显大于能耗效应,电网投资向西部倾斜有利于减缓整体能源消费增长,电网投资优化是控制能源消费总量的一个重要方面。尽管如此,市场化的价格机制仍是抑制能源消费增长过快的根本途径。

Under a framework of profit function, this paper examines the impact of power grid on regional energy consumption and economic growth. The major findings are： grid development promoted both regional economy and energy consumption, but the impacts were significantly different among regions. In particular, in the western provinces the impact on economic growth was greater than that on energy consumption, implying that grid investment inclined to the west could be conducive to decelerating China＇s total energy consumption. However, while optimal allocation of grid investment is important to control total energy consumption, market-based pricing is fundamental in long-term.
