农业机械化对农业贡献率测算方法研究

Methods Development to Estimate the Mechanization Profit in Agricultural Industry

测算农业机械化对农业生产的贡献份额 ,实践上有助于从总体上把握农业机械化的发展水平、发展潜力和趋势 ,对农业机械化事业的决策具有重要的参考价值 ;理论上研究产业系统单因素的贡献率具有学术意义。该文在分析国内外生产率理论和测算方法的基础上 ,设计了运用柯布 -道格拉斯生产函数和项目有无比较法进行农业机械化对农业贡献率的测算方法。

Profit estimation for the mechanization in agricultural industry is useful to understand the development level, potential, trend of agricultural mechanization for government decision making and it is also an answer to how to estimate the single factor's influence on a complicated economic system. Based on analyses of the productivity theory and methods, two methods were developed to estimate the profit portion of mechanization in the agricultural industry by the Cobb Douglas production function and a comparison of mechanization and no mechanization in agricultural industry.
