摘要
本文用实证的方法研究中国与八个发达国家之间人均GDP差异的收敛性及其能源消费强度随人均GDP变化的收敛性。本文的研究结论是:第一,中国与八个发达国家之间的人均GDP差异存在收敛,随着人均GDP差异的收敛,中国与八个发达国家的能源消费强度差异也是收敛的,并且收敛速度快于人均GDP的收敛速度。第二,能源消费强度随产业结构的改善、能源价格的提高、技术进步和固定资产投资的扩大而降低,随FDI的增加而略有提高。第三,能源消费强度的差异随中国与八国间的固定资产投资差异、能源价格差异、技术进步差异的缩小而缩小,但随FDI差异的缩小而有微小的增加,与产业结构差异的相关性没有通过显著性检验。第四,中国与八国人均GDP差距的降低可以引起能源消费强度差异减小的原因在于投资差异、技术差异、价格竞争机制差异等决定经济增长差异的因素可以明显影响能源消费强度差异。
We analyze empirically the convergence of per capita GDP as well as the convergence of energy intensity between China and the U.S. , Japan, the U.K. , Germany, France, Canada, Italy and Netherland. Our findings are as follows： Firstly, There are two convergences between China and the eight advanced countries, per capita GDP and energy intensity. That is, 1% decrease of the difference of per capita GDP can result in 1.55% smaller difference of energy intensity between the concerned countries. Secondly, the energy intensity decrease with the improvement economic structure, higher energy price, technology progress and more fLxed asset investment and a slight increase, however, with higher FDI. Thirdly, the difference of energy intensity decrease with the narrower difference of fixed asset investment, energy price, technology progress and a slight increase, however, with the smaller difference of FDI. The economic structure, however, can not pass the t-test in our difference regression. Fourthly, in terms of the concerning countries, the economic mechanism that the decrease of difference of per capita GDP can lead to smaller energy intensity difference is that the difference of determinants of economic growth such as investment, technology progress and price competitive mechanism can impact the difference of energy intensity significandy.
