本文通过分析1997--2006年我国西部和东部省区之间的能源强度差异与劳均GDP差异之间的关系，在使用滞后调整的面板数据模型基础上，分别对省区及其六个产业部门的劳均GDP收敛性及其能源强度随劳均GDP变化的收敛性进行实证估计，得到以下结论：第一，六个产业部门和省区都存在劳均GDP收敛，其中，建筑业的收敛速度最快、工业最慢。第二，东西部省区之间总体的能源强度差异是收敛的，即随着东西部省区之间劳均GDP差异的缩小，其能源强度差异也在缩小，但收敛的速度慢于劳均GDP的收敛速度。第三，西部各个产业部门相对于东部其能源强度差异收敛性存在差距，东西部省区之间在农林牧渔业、建筑业和工业上的能源强度差距是收敛的，而在其余部门上的能源强度差距是发散的。第四，西部各省区整体能源强度的收敛性与其各产业部门的收敛性并不一致，而是存在显著的差异，这说明西部各省区应该在产业部门层面上采取措施才能更加有效地提高其整体能源使用效率。

This paper analyzes the relationship of energy intensity differences and productivity differences between the Eastern and Western region in China from 1997 to 2006. Based on lagged adjusted panel data model, we estimate empirically the convergence of energy intensity with productivity convergence of the province and six major sectors （agriculture, industry, construction, transportation/ post and telecommunication, wholesale and retail trades and catering, other sectors of the tertiary industry ） respectively. Our findings are as follows ： Firstly, there is productivity convergence in the six sectors and province, of which the construction sector has the fastest convergence speed and the industry slowest. Secondly, the overall energy intensity gap between the eastern and western provinces is converging, that is, the energy intensity difference decreases as the productivity gap narrowing, but the convergence speed of the energy intensity is slower than that of productivity. Thirdly, the energy intensity differences for six sectors between the eastern and western provinces are differences. Agriculture, industry and construction show convergence and other sectors show divergence. Fourthly, there are great differences of the energy intensity convergence between each sector and the whole within an individual province in the western region, which suggests that the western province should adopt sectoral policy to promote its whole energy efficiency.
