科技进步对我国陆地黄瓜种植贡献率实证分析

在综述科技进步定义和测定方法的基础上,选择基于前沿生产函数和技术效率分析原理的科技进步测定方法,并以2002和2003年我国主要省市陆地黄瓜成本收益资料为样本,应用SPSS统计分析软件测定了我国主要省市在2002~2003年的硬技术进步贡献率、软技术进步贡献率及要素投入贡献率。结论为:就全国平均水平而言,以软技术进步为代表的科技进步对我国陆地黄瓜产量有积极的正效应影响;我国陆地黄瓜生产存在着明显的差异性和不均衡性;我国存在5种类型的陆地黄瓜生产区域。

Study on the Contribution of S&T to Cucumber Production in China

Cucumber is the main vegetable product in China and there exists positive meaning in science and technology contribution rate to cucumber outputs, On the basis of definition and methods about science and technology progress contribution rate, the method of frontier production function and technique efficiency analysis were chosen in the thesis. The contribution rate of hard technology progress, soft technology progress and the essence factor inputs of the main cities and provinces in China were calculated respectively through the cost and profit samples of land for cucumber production and the statistic analysis software SPSS was applied to estimate the parameters and calculate the contribution rate. The conclusion was that at average level, the science and technology progress especially the soft technology progress had positive effect on the cucumber production; there existed obvious discrepancy and unbalance in the dry land cucumber production; five different kinds of areas can he distinguished according to the results.
