产业结构对区域能源效率贡献的空间分析——以中国大陆31省(市、自治区)为例

Spatial Analysis on the Contribution of Industrial Structure Change to Regional Energy Efficiency——A Case Study of 31 Provinces in China's Mainland

能源是重要的生产要素,由于增加能源要素投入,人类的劳动生产率得到了极大提高,推动了经济与社会发展。产业结构变动是影响区域能源效率提高的重要因素。在现代经济发展过程中,产业结构升级与提高区域能源效率密切联系,产业结构状况与能源效率共同反映一国的经济发展方向、发展水平和经济可持续发展能力。论文从空间角度探讨产业结构变动对区域能源效率提高的贡献,利用三次产业结构GDP和相关能源利用统计数据,结合数学模型和空间分析方法,以中国大陆31个省(市、自治区)相关数据为样本,分析得出中国大陆31省(市、自治区)产业结构变动对能源效率提高贡献的空间差异较大;产业结构合理且经济基础较好省(市、自治区)、经济发展起步较晚省(市、自治区)以及处于产业结构调整初期的中国中西部欠发达省(市、自治区)产业结构变动对区域能源效率提高的贡献明显;而经济基础薄弱尚未形成主导产业的省(市、自治区)与形成较为合理低端产业结构的省(市、自治区),产业结构变动对区域能源效率提高的贡献不明显。

Energy is an important production factor.With more energy put into production activities,labor productivity has been increased greatly,which promoted economic and social development in consequence.Industrial structure change is an important factor which affects growth of regional energy efficiency.In modern economic development,industrial structure improvement is closely related to regional energy efficiency and the status of industrial structure and energy efficiency can together reflect one country＇s development level,sustainable development ability and the direction in which its economy will be heading.This paper aims to discuss the contribution of industrial structure fluctuating to regional energy efficiency growing in spatial perspective.Based on 31 mainland provinces in China,using the statistics of industrial structure and corresponding energy utilized data,adopting mathematic model and spatial analysis approaches,it is found that 31 provinces differed in contribution of industrial structure fluctuating to regional energy efficiency growing.The outcome reflected contribution is obvious in those provinces with appropriate industrial structure and good economic basis and the ones developed late as well as the undeveloped middle and western provinces which were in initial stage of industrial restructuring,but that is obscure in those provinces which have not developed leading industries with weak economic basis as well as the ones with relatively fitting low end industrial structure.
