【摘要】：论文以Leontief投入产出分析为基础,利用系统优化模型测算中国的生态效率,并分析生产要素、产业产出和污染物对效率水平的影响;为了聚焦于低碳经济发展,模型仅包括温室气体一种污染物。从1997到2010年,中国生态效率约下降一半,要素投入和产出变动均是效率降低的原因。在劳动、资本和土地三种要素中,惟有高水平劳动影子价格为正、能够影响生态效率;1997—2010年间,高水平劳动力实际利用率降低、稀缺性上升,加剧了实际生产与前沿面的距离、降低了生态效率。在18类产业中,12类产值上升、对生态效率贡献为正;食品、纺织、非金属制造、运输及公私服务业等6类对生态效率作用为负。以上结果有助于明确实现保增长、减排放的关键产业部门和要素投入。
[Abstract]:Based on the Leontief input-output analysis, the paper uses the system optimization model to estimate the ecological efficiency of China, and analyzes the effects of production factors, industrial output and pollutants on the efficiency level, in order to focus on the development of low-carbon economy.The model includes only one greenhouse gas pollutant.From 1997 to 2010, the ecological efficiency of China decreased by about half, and the change of input and output was the reason for the decrease of efficiency.Among the three factors of labor, capital and land, only the high level of labor shadow price is positive, which can affect the ecological efficiency. During the period 1997-2010, the actual utilization rate of the high level labor force decreased and the scarcity increased.It intensifies the distance between the actual production and the front and reduces the ecological efficiency.In 18 kinds of industries, the output value of 12 categories increased, and the contribution to ecological efficiency was positive, while 6 categories of food, textile, non-metal manufacturing, transportation and public and private services had negative effects on ecological efficiency.The above results are helpful to clear the key industrial sectors and factors to ensure growth and emission reduction.
