金砖五国能源消费强度及其收敛的原因探析——基于与欧美等发达八国的比较

An analysis of Driving Causes of BRICS'Energy Consumption Intensity and Its Convergence: A Comparative Study on Eight Countries

本文采用面板数据模型,对金砖五国与欧美等发达八国能源消费强度的影响因素进行比较研究,并在此基础上对中国和南非能源消费强度收敛的原因展开分析。分析结果表明:产业结构、能源价格、固定资产投资和技术进步对能源消费强度的下降产生积极影响,而能源结构不利于其进一步的降低。在能源消费强度收敛原因分析中,价格竞争机制和技术进步差异对中国和南非能源消费强度收敛均有显著影响;而产业结构和固定资产投资差异仅对中国能源消费强度收敛影响显著,能源结构差异仅对南非能源消费强度收敛影响显著。

Using the panel data model, this paper makes an empirical research on influencing factors to BRICS＇ in- tensity of emery consumption. On this basis, the paper investigates the reasons for China＇s or South Africa conver- gence of energy consumption intensity. The results show that industry structure, energy price, fixed assets invest- ment and technological progress have positive effects on energy consumption intensity, while energy structure is contrary. Among them, technological progress and the mechanism of price competition promote the reduction of the difference of energy consumption intensity between China, South Africa and developed countries. While the differ- ence of industrial structure and fixed assets investment has an effect on China＇s convergence of energy consump- tion intensity, the difference of energy structure has a significant impact on South Africa＇s.
