南京市农业科技进步贡献率的测算与分析

Calculation and Analysis of Contribution Rate of Agricultural Science and Technology Progress in Nanjing

基于C-D生产函数的增长速度测算模型,以南京统计年鉴中2002-2007年的各区县农业统计数据为基础,对2002年到2007年间的南京农业科技进步贡献率进行了估计与分析。研究表明,南京市农业科技进步贡献率在波动中上升,达到了54.78%左右,但仍然存在着依靠物质投入过重的因素。

Based on the agricultural statistics of all Districts and Counties from 2002 to 2007 in the Nanjing Statistical Yearbook, the paper analyzes the contribution rate of agricultural science and technology progress in Nanjing by means of C-D production function growth speed calculation model. The research indicates that the contribution rate of science and technology progress in agriculture is rising among fluctuation, and reaches about 54.78%. But the problem of too much independence on material input still exists.
