摘要
以南京市为例,采用Tornqvist指数法计算和分析了1991—2005年中国地区农业全要素生产率(TFP)的增长率,并对TFP增长的来源进行分解,估算了对TFP增长有促进作用的各类关键因素的贡献率。根据TFP增长贡献率的大小,对中国地区农业现代化发展提出了一些对策性建议。主要研究结论如下:支农及农业事业费、农田灌溉率、农业劳动者每日工资与人均非农年收入的比值都对TFP的增长具有统计意义上的正的重要影响;而农产品生产价格指数对TFP有着统计意义上的负的影响。
This paper constructs Tornqvist index to calculate and analyzes movements in total factor productivity(TFP) of agriculture in Nanjing from 1991 to 2005. It analyses the sources of TFP growth and researches contributions of several key factors. The main conclusions are as fol lows:agro-based and agricultural administration,field irrigation rate,the daily wages of agricultural laborers with per capita non-agricultural income ratio has a positive impacts on statistical significance for TFP growth respectively,and production price index has an negative impact on statistical significance for TFP growth.
