技术进步对云南省经济增长贡献的实证研究

Technological Advances Contribute to Economic Growth Empirical Study in Yunnan Province

选取1993-2011年云南省农业投入和产出的数据，采用改进的随机前沿生产函数模型，对云南省农业经济发展进行实证分析，同时运用索罗余值的思维，将技术效率看做土地要素、劳动力要素、资本要素的余值，分析技术进步对衣业经济发展的贡献率，并判断云南省农业经济发展的类型。研究结果显示，随着时间推移，劳动力要素、土地要素以及农村固定资产投资对农业经济总产出有显著正向作用。在总体上农业技术进步贡献率是提高的，但个别年份波动较明显。劳动力要素贡献率基本上保持平稳的态势，然而，农村固定资产投资要素贡献率在研究样本年限期间波动幅度较大，相对而言，土地要素贡献率处于中等水平，并且云南省农业经济发展属于粗放型经济增长方式。

This paper selected 1993-2011 agricultural inputs and outputs data in Yunnan Province and used an improved stochastic frontier production function model to analyze Yunnan＇s agricultural economic development, while used of Solow residual thinking, technical efficiency will be seen as the land elements of the labor factor, residual capital factor analysis technologieal progress contribution rate of agricultural economic development, and to determine the type of agricultural economic development in Yunnan province. The results showed that labor factor, land elements as well as rural fixed assets investment for the total output of the agricultural economy has a significant positive effect. Technology advances in agriculture in general is to increase the contribution rate, but more pronounced fluctuations in individual years. Labor factor contribution rate remained essentially stable trend, however, elements of rural fixed assets investment contribution rate during the life of the study sample fluctuating, relatively speaking, land factor contribution rate at the middle level and economic development of agriculture in Yunnan province is the extensive economic growth mode.
