中国地区工业部门二氧化碳排放量及碳排放约束下全要素生产率测算

估算了电力、热力的CO2折算系数,据此精确测算了1995—2008年中国29个省(自治区、直辖市)工业部门的CO2排放量,并运用方向性距离函数模型计算了考虑和不考虑CO2排放两种情形下各省区的工业TFP。结果显示:考虑CO2排放时中国工业部门的TFP增长率(碳效率)比不考虑CO2排放时高出2个百分点;东部地区的工业部门在两种情形下均是推动前沿技术进步的主要力量,且在考虑CO2排放情形下表现更为突出;2000年后,中部地区个别省份的工业部门开始进入技术前沿。结论表明:中国工业的可持续发展取得了显著成绩,其中东部地区的工业发展一直走在全国前列;虽然中、西部地区工业部门的技术追赶总体上相对缓慢,但近几年个别省份也在加快步伐;2003年后中国全要素CO2排放效率增长放缓甚至出现负增长。

Estimation on Carbon Emission and Total Factor Productivity under Constraint of Carbon Emission of Regional Industrial Sectors in China

This paper evaluates the carbon emission coefficient of electric power and heating power,and calculates the CO 2 emission of industry sectors in 29provinces of China during 1994-2008.And it estimates the industrial TFP of 29provinces by using the directional distance function in two cases,namely considering CO2emission and not considering CO2emission.The result shows as follows :,industrial TFP growth rate when considering CO2emission is higher by 2percentage points than that when not considering CO2emission;eastern China performs best in both situations,especially considering CO2emission;some provinces in western and middle area entered the production frontier after 2000.It finds as follows : the sustainable development of China's industry has acquired remarkable achievements,that in eastern area performed best;relatively,the technological catching-up in western and middle area are slow,but some provinces walked faster in recent years;the industrial TFP growth of China since 2003is slow,even shows a negative growth.
