电力生产、跨省交易与能源环境效率

Electric Power Production,Inter-provincial Trade and Energy Environmental Efficiency

将电力生产作为先行于其他社会生产的生产环节,在考虑规模越来越大的电力跨省交易和非期望产出(二氧化碳排放、工业废气总排放量、工业废水总排放量等)的基础上,使用非参数网络数据包络分析模型测算了2000—2012年中国省域能源环境效率。结果表明:与考虑电力生产和跨省交易的网络DEA模型相比,利用传统DEA方法会高估电力输入省的能源环境效率、低估电力输出省的能源环境效率。指出调整电力生产布局和跨省输送网络可以有效提高地区的能源环境效率。

Taking the power generating as the first production stage,and GDP production as the second stage,and considering undesired outputssuch as COz emission,industrial waste gas emission and industrial waste water emission and so on, this paper calculates China^s provincial energyenvironmental efficiencies in each stage and the whole production from 2000 to 2012 by using the non-parametric network DEA model. The re-sults show that, comparing with the network DEA model considering electric power production and inter-provincial trade, traditional DEA modelovervalues energy environmental efficiencies of provinces which trade in large scales of power, and undervalues those of the provinces trading outlarge scales of power. And it points out that rearranging the power generation and transportation among Chinese regions could improve Chineseregional energy environmental efficiency.
