中国各省循环经济发展效率——基于动态DEA方法的研究

Provincial Circulation Economy Efficiency in China——Analysis based on Dynamic DEA Model

以工业"三废"的排放量作为负向产出指标,以工业总产值、工业企业从业人数和能源消费量作为正向投入指标,来评估各省的循环经济运行的效率水平。研究表明,再利用效率较高的省份主要分布在我国东南沿海,而排放效率较低的省份集中在西南、西北地区。绝大部分省份的再利用效率上升,技术效率提高和技术水平提高各贡献了一半的增长率。

Industrial sector is selected as the representative department with ＂three wastes＂ as negative output indicators and gross industrial output value, industrial workers and energy consumption as positive input indicators. Our research shows that provinces with higher recycling efficiency are mainly distributed in the southeast coastal area, while provinces with lower efficiency are concentrated in the southwest and northwest. Reuse efficiency is increasing in most provinces. Nationally, reuse efficiency shows rising trend, technical progress and higher tech-utilization contribute half of the growth each.
