技术进步对我国茶叶生产贡献率的估算

技术进步对20世纪80年代我国茶园生产增长的贡献率，在很大程度上能反映近30年技术创新对我国茶叶生产的影响。柯布－道格拉斯生产函数和索罗余值法的分析结果表明，1980年－1991年单产增加由时间变量解释部分为84．2％，它和集体茶场经营制度改革、技术创新以及幼龄茶园逐渐进入成年采摘期等因素有关，而1985年－1991年期间56．1％部分则主要是技术进步所致。

Quantitative Assessment on Contribution of Technical Progress to the Tea Production in China

Contribution rate of technical progress to the tea productivity during 1980s in China, to large extent, can illustrate the effect of technical innovation on Chinese tea production in the last thirty years. The result, by applying Cobb Douglas Production Function and Solow's Residual Method. showed that 84.2% of the increase in per unit area yield from 1980 to 1991 was explained by time variable, which was related to the popularization of household contract responsibilitysystem? technical innovation and previously planted tea seedling growing into adult. The 56.1% of the increase from 1985~1991 was mainly contributed by technical progress.
