基于岭回归模型的台湾水稻科技进步贡献率的测算与分析

摘要

A ridge regression model for the rice production in Taiwan from 2000 to 2014 was constructed with the trans-log production function and parameter estimation. Information on the output elasticity, as well as the contribution of various factors toward the improvements,of the rice production in Taiwan was obtained.It was found that the scientific and technological advancements was the major driving force contributing 51.51% on the rice production improvements in Taiwan during those years.As a result,capital investment ushered in the progress and became the main factor,followed by proj ects executed that upgraded the land use on the island.The generally improved skills of the farmers also appeared to play a crucial role in Taiwan's rice productivity.%通过建立超越对数生产函数,建立2000-2014年期间台湾水稻生产模型,并运用岭回归(Riolge Regression)方法估计参数,得到台湾水稻生产各要素的产出弹性和科技进步贡献率。研究表明,科技进步是台湾水稻生产的主要驱动力,2000-2014年间台湾水稻科技进步贡献率为51.51%。在台湾水稻生产中,科技进步最主要以资本的形式促进水稻产量的提升,其次通过改良土地的方式,不断提升水稻生产力,还有一部分科技进步以提高稻农的综合素质水平达到促进水稻生产的目的。
