本文在GIS工具和泰尔指数的支持下，通过对2005年中国大陆30个省会城市的规模、效率和结构的平行比较和定量分析，探讨了中国城市能源消费的空间差异。与城市能源消费相关的指标在不同地区表现出较大的空间差异，这可能是由于中国地理特征、经济发展水平和当地能源供应情况的差异所致。从绝对值来看，我国能源消费总量最高的城市大多分布在京津唐、长三角、珠三角等经济发达地区，但中西部地区城市人均能源使用量明显较高。从能源结构看，煤炭仍占主导地位，中西部地区城市对煤炭的依赖程度较高。相比之下，东南沿海地区和北方发达地区更多地使用电力、石油等优质能源载体。能源密集型城市主要分布在西北地区，能源效率较高的城市分布在东南部地区。泰尔指数也验证了城市能源消费的巨大空间差异。就中国东、中、西部经济区而言，群体内的不平等是造成总体差异的主要因素，如群体内人均能源消费泰尔指数为0.18，远高于群体间的0.07，其他指标也同样如此。因此，鉴于中国城市能源消费的空间差异，迫切需要对城市能源系统进行区域化、类型化管理，以有效实现当前的能源战略和目标。
With support of GIS tools and Theil index, the spatial variance of urban energy consumption in China was discussed in this paper through the parallel comparison and quantitative analysis of the 30 provincial capital cities of mainland China in 2005, in terms of scale, efficiency and structure. The indicators associated with urban energy consumption show large spatial variance across regions, possibly due to diversities of geographic features, economic development levels and local energy source availability in China. In absolute terms, cities with the highest total energy consumption are mostly distributed in economic-developed regions as Beijing-Tianjin-Tangshan Area, Yangtze River Delta and Pearl River Delta of China, however, the per capita urban energy use is significantly higher in the Mid-and-Western regions. With regard to the energy mix, coal still plays the dominant role and cities in Mid-and-Western regions rely more on coal. In contrast, high quality energy carrier as electricity and oils are more used in southeast coastal zone and northern developed areas. The energy intensive cities are mainly located in the northwest, while the cities with higher efficiency are in southeast areas. The large spatial variance of urban energy consumption was also verified by the Theil indices. Considering the Chinese economy-zones of East, Middle and West, the within-group inequalities are the main factor contributing to overall difference, e.g., the Theil index for per capita energy consumption of within-group is 0.18, much higher than that of between group (0.07), and the same applies to other indicators. In light of the spatial variance of urban energy consumptions in China, therefore, regionalized and type-based management of urban energy systems is badly needed to effectively address the ongoing energy strategies and targets.
