中文摘要：

借鉴TFP分解分析法，将TFP分解为技术进步与规模报酬两方面，选用引入劳动节约型技术进步因子的柯布一道格拉斯生产函数，根据中国各地区1985—2011年的年度数据，估算出各地的平均技术进步率和规模报酬情况。研究结果表明：东部地区和中部地区存在规模报酬递增的态势，而西部地区存在规模报酬不变的现象；东部和中部地区存在明显的劳动节约型技术进步，其中东部地区的技术进步率高于中部地区。

英文摘要：

Total Factor Productivity （TFP） is fcbompesed into two aspects of technological progress and returns to scale in this paper. According to the annual data of various parts of China from 1985 to 2011, this paper has estimated the average rate of technological progress and the coefficient of returns to scale by the Cobb - Douglas production function for introducing the factor of laborsaving technology progress. The results show that there are increasing returns to scale in east and central in regions as well as constant returns to scale in west regions. At the same time, the obvious labor - saving technology improvement exists in both east and central in China, and the east is slightly higher than the center. Based on this analysis, this paper puts forward relevant policy suggestions.
