西藏农业经济增长影响因素的实证分析

An Empirical Analysis of the Influencing Factors of Tibet Agriculture Economic Growth

本文以探索西藏农业经济影响因素为目的,利用1990-2012年西藏统计数据,基于柯布——道格拉斯生产函数建立实证模型,分析西藏农业经济增长影响因素。结果表明,现阶段西藏农业劳动力存在严重过剩,阻碍了农业发展,农业机械化程度和耕地有效灌溉率提高可以有效促进农业增长,化肥施肥结构亟须优化,仅化肥施用量增加对农业生产没有显著影响。

This paper aims to explore the influencing factors on the agricultural economy in Tibet with sta-tistics from 1990 to 2012 and empirical analysis based on the Cobb-Douglas production function model. The re-sults show that excess agricultural labor force hindered the development of agriculture in Tibet. The degree ofmechanization of agriculture and the rate of land irrigated agriculture can effectively promote economic growth.Fertilization structure needs scientific optimization, and only the amount of chemical fertilizer has no significantimprovement on agricultural production.
