我国广义农业经济增长的要素贡献研究——基于面板数据模型的实证分析

A Study on the Factors'Contribution to China's Generalized Agricultural Economic Growth

通过对2000年到2005年大陆除西藏外30个省份广义农业经济增长的研究,发现广义技术进步在农业经济增长中贡献最大,农业经济增长存在规模经济报酬递减现象。规模经济报酬递减与农业本身分工困难有关。因此,促进农业经济增长应大力推进技术进步,建立健全农业社会化服务体系,拉长产业链条,实现规模经济报酬递增。

This paper studies the generalized agricultural economic growth of 30 provinces in China main- land except Tibet from 2000 to 2005 with panel unit and panel cointegration. The finding of our study shows that technological progress has the highest contribution ratio to production value and that the agricultural economic tp, owth is in the state of diminishing returns to scale. The state stems from the difficulties of labor division. Therefore, to promote the agriculture economic growth, we should vigorously promote the technological progress. At the same time, we should establish the perfect agricultural socialized service system to get a long industrial chain. So the agriculture economic growth can reach the state of increasing returns to scale.
