甘肃省经济增长影响要素变化的实证分析

Empirical Analysis on the Change of Factors to Gansu Economic Growth

通过对柯布-道格拉斯生产函数引入虚拟变量,从而实现对现实经济更好的反映.分析甘肃省劳动投入和产出散点图,并结合实际经济背景以及邹式转折点检验,可以看出在1993年前后甘肃省劳动投入和产出之间的关系发生了明显改变,以此为分界点引入虚拟变量构建生产函数回归模型,对模型进行估计和检验,从而得出甘肃省在1993年后劳动对产出贡献程度增加的结论,并结合当时经济环境,分析产生变化的原因,提出相应的政策建议.

In this paper,by introducing virtual variables to Gobb Douglas production function,the real economic condition was reflected. By analyzing input- output table,and combining economic background and turning point,we can get a conclusion that the input-output relationship before 1993 had changed obviously,furthermore,the recursive model of production function was setup to analyze production contribution after 1993. Finally,some policies were proposed for economic environment.
