21世纪以来，伴随经济的高速发展，区域经济发展不平衡的问题日益突出，东部地区的经济发展水平和中西部地区的经济发展水平差距很明显。稳定的经济发展要求与之相匹配的能源持续投入增加，而我国能源资源大多数分布在西部地区，能源消费主要集中在中东部地区，这就意味这单一的经济增长方式并不适用我国不同区域能源消费方式，如果不考虑区域间能源消费差异和经济发展水平的差异，这将影响实现以节能减排为基础追求经济可持续稳定的目标。 本文借鉴区域经济增长与能源消费强度差异收敛性理论，首先根据1995-2011年全国各省份的人均GDP数据，运用聚类分析技术将我国聚类为发达地区、发展地区、不发达地区，并以此作为研究区域，对有关经济增长差异与能源消费强度差异进行区域内以及区域间对比分析，其次以发达地区为基准，建立三大区域的人均GDP收敛模型；不发达地区与发达地区的能源消费强度差异随人均GDP差异收敛模型；发展地区与发达地区的能源消费强度差异随人均GDP差异收敛模型，利用双向固定效应面板模型对其进行实证检验，发现我国各区域之间人均GDP增长存在收敛态势，能源消费强度收敛的速度比人均GDP 的收敛速度稍慢些，即不发达地区与发达地区的人均GDP的差异每缩小1%，能源消费强度的差异就缩小0.3225%；发展地区与不发达地区的人均GDP的差异每缩小1%，能源消费强度的差异就缩小0.1657%。 根据实证结果，本文建议区域政府在制定保障经济增长及节能减排策略时，应充分考虑区域能源消费强度随经济增长的收敛特征，确保在实施节能减排策略时保障经济的持续增长。

Along with the rapid development of economy since the 21th Century, the imbalance of regional economic development issue has become increasingly prominent—the gap between the Eastern Region’s economic development and that in the Midwest Region’s is obvious. Steady Economic development is request to match the demand for the sustainable energy investment. Although most of the energy resources in China are mainly distributed in the west, its consumptions are mainly concentrated in the east. This also implies that the single economic growth mode was not suitable for the different ways of regional energy consumption in our country. If we don’t consider the regional differences between energy consumption and economic development level, this will depend on energy conservation and emissions reduction, the pursuit of economic sustainable stability target will run in opposite directions. Acorrding to the theory that the Regional economic growth and energy consumption intensity difference, first of all, the provinces of the country's per capita GDP data, using cluster analysis technology will be divided into the developed areas in China from 1995 to 2011, development areas and underdeveloped areas as the study area, then the differences on economic growth and energy consumption intensity differences within the region and regional comparison analysis, secondly in developed areas as a benchmark, three regional GDP per capita convergence model is set up; Underdeveloped areas and developed areas of convergence model with GDP per capita energy consumption intensity differences; Development areas and developed areas of convergence model, with a per capita GDP energy consumption intensity differences with bidirectional fixed effect panel model to empirical test, The results show that China's regional GDP per capita growth convergence trend, energy consumption intensity of convergence rate than the speed of convergence in per capita GDP slightly slower, But the difference in per capita GDP underdeveloped area and developed area of each reduced 1%, the difference of energy intensity is reduced by 0.3225%; developing and less developed areas of the differences in GDP per person per 1% reduction, the difference of energy consumption intensity is reduced to 0.1657%. According to the empirical results, this paper suggests that the regional government in formulating security economic growth and energy saving and emission reduction strategy, should fully consider the convergence characteristics with the economic growth of regional energy consumption intensity, ensure that sustained economic growth in the implementation of energy-saving emission reduction strategies.
