中国地区经济增长与能源消费强度差异分析

Regional Economic Growth and Differences of Energy Intensity in China

本文假设我国西部与东部地区的能源消费强度差异是西部与东部地区人均GDP差异的函数,然后同其他回归变量一起检验这两个变量之间的关系,并通过使用面板数据计量经济学模型进行实证估计。本文的研究结论为:第一,总体而言,西部与东部地区的人均GDP差异存在收敛,随着人均GDP的收敛,西部与东部地区的能源消费强度差异也是收敛的,但收敛的速度慢于人均GDP的收敛速度。第二,不同西部省份在经济增长过程中的能源使用效率是收敛还是发散存在差异。本文的政策含义是:政府在制定区域经济发展战略时,要鼓励和引导各地区充分利用能源禀赋以及能源利用效率方面的差异进行合作,走能源节约型的可持续的区域平衡增长道路。

We suppose that the difference of energy intensity between the Western region and the Eastern region in China is the function of the difference of per capita GDP between the two regions. Then we model the relationship between the two variables together with other regression variables and estimate the coefficients by panel data of 30 provinces from 1995 to 2002. Our findings are as follows. Firstly, the difference of per capita GDP tends to convergence between the Western region and the Eastern region. The difference of energy intensity between the two regions, as a whole, also tends to convergence with the convergence of per capita GDP although the convergence speed of the energy intensity is slower than the convergence speed of per capita GDP. Secondly, it is different that the energy intensity of individual province in the Western region shows convergence or divergence. The policy implication of this paper is that the government should encourage and guide different provinces to cooperate by taking advantage of their own energy endowment and the difference of energy intensity when the government makes the strategy of regional economic development. As a result, regional economic growth can be based on saving energy, regional balance and sustainability.
