基于DEA-Tobit模型的山东省全要素能源效率研究

能源是经济发展的驱动力,提高能源效率有利于保障经济持续健康发展。利用DEA模型下的BCC模型和Malmquist指数法对山东省的全要素能源效率进行测算,运用Tobit模型对山东省能源效率的影响因素进行实证分析。结果表明,山东省全要素能源效率整体呈上升趋势。山东省能源效率主要受六种因素的影响,其中技术进步、能源相对价格、能源消费结构、市场化程度为正向影响,产业结构、对外贸易为反向影响。提高科技转化率、优化产业配置效率、调整能源相对价格、强化能源替代性等有助于山东省能源效率的提高。

Research on Total Factor Energy Efficiency of Shandong Based on DEA-Tobit Model

Energy is the driving force of economic development and improving energy efficiency is beneficial to the sustained and healthy economic development. In this article, BCC model and Malmquist index of DEA model are used to estimate the total factor energy efficiency of Shandong and Tobit model is used to make an empirical analysis of the influence factors. The result shows that the total factor energy efficiency of Shandong province is on the rise, and that among the six influence factors, technological progress, energy prices, energy consumption structure and the degree of market have positive effects, while industrial structure and foreign trade have negative effects. Measures to improve energy efficiency of Shandong include improving the rate of technology transfer, optimizing industrial allocation efficiency, adjusting energy relative price and intensifying energy substitution, etc.
