基于势分析理论的广西科技进步贡献率测算

Calculation of contribution rate of sci-tech progress based on the analysis of potential theory in Guangxi

摘要:

科技进步作为经济增长的内在动力，推动社会生产力不断向前，实现经济社会的繁荣与发展。通过总结国内外有关科技进步贡献率测算的分析方法，在柯布-道格拉斯生产函数的基础上引入势分析理论，建立势生产函数模型来测算广西科技进步贡献率。选取1991年至2013年的广西数据对十四个滚动经济周期的科技进步贡献率进行测算，实证分析结果表明，广西自1991年以来，全要素生产率均大于1，说明投入要素的利用程度高于平均水平；同时科技进步贡献率水平低，说明广西创新驱动的效能还有待提升，需要在保证资本产出效率不断提高的基础上，切实提高劳动生产率，保证广西科技进步对经济增长的贡献率不断提高。

Abstract:

: Sci-tech progress as the internal driving force of economic growth, promote the social productive forces continue to move forward to achieve economic and social prosperity and development. This article summarizes the calculation of the contribution rate of sci-tech progress in the domestic and foreign quantitative analysis method, the introduction of the concept of the potential theory on the basis of the Cobb - Douglas production function to establish the potential production function model to measure the progress of sci-tech rate in Guangxi. Select the data of Guangxi between 1991 and 2010 to calculate the contribution rate of sci-tech progress for 11 of the scroll of the economic cycle. The empirical analysis results indicated that, since 1991, the entire essential factor productivity has been bigger than 1, which explained the investment resources the degree of utilization is higher than the average level. However, since 1998 -2007, the contribution of sci-tech progress on economic growth rate declined due to the severe decline of labor productivity on the degree of contribution to economic growth. At the same time, the contribution to the growth rate of capital value rate is rising, but the increase is less than the decline in labor productivity growth.
