基于泰尔指数的中国城镇生活能源消费区域差异及贡献度研究

运用泰尔指数法，在八区域分区方式下对中国城镇生活能源消费的区域总差异进行测度，并比较八大区域内部省际差异及其变动趋势，同时分析区域间差异和区域内差异对总差异的贡献程度。将以城镇居民收入和城镇人口为权重的两种泰尔指数进行比较，研究居民生活水平及人口因素对生活能源消费区域差异的影响。结果显示：2000年至今，中国城镇生活能源消费的总体差异呈不断缩小趋势，而以城镇居民收入为权重计算的泰尔指数更能揭示区域能源消费的差异，以人口为权重则部分掩盖了这种差异；中国城镇生活能源消费总体差异主要来自于区域间差异，其贡献率始终维持在60%-70%之间；区域内差异主要是由南部沿海、东部沿海和中部区域内部的省际差异造成的。应转变城镇化推进方式，并制定更具针对性的区域协调发展政策，以减小生活能源消费差异、促进区域协调发展。

Regional Difference of Urban Household Energy Consumption and Contribution Degree in China A study based on the Theil Index method

Based on the eight regions of China and the method of the Theil index, this paper has measured the total regional difference of urban household energy consumption, compared the inter provincial differences and their changing trends of the eight regions and analyzed the contribution of the difference among regions and within regions. To analyze the impact on regional difference caused by the living standard of urban residents and population, this paper has compared the Theil index which takes the urban income and urban population as weights. The results show that the overall difference of Chinese urban household energy consumption is getting smaller from 2000 to now, and the difference is revealed by the Theil index based on the urban income while partly covered by the Theil index based on urban population. China urban life energy consumption difference mainly comes from the regional differences whose contribution rate is always maintained between 60%-70%, and the regional differences are mainly caused by the interprovincial differences in southern, eastern coastal regions and central regions. It is suggested that we should change the way of urbanization and develop a more targeted regional policy to reduce the energy consumption differences and promote coordinated regional development.
