【摘要】 本文首先讨论了要素投入和要素生产率研究的经济学基础,分析了我国投资、全要素生产率和产出增长之间的关系。在此基础上,结合我国公路发展的历程、适应性分析,论述了公路建设投资与产出及全要素生产率之间的关系。然后给出了公路建设产出、全要素生产率比较研究方法框架。在框架基础上对公路建设产出效果计算方法进行了比较研究,对生产函数法在中国应用时,函数中资本要素的性质进行了重新界定,并给出了方法使用场合的判别方法;对全要素生产率的计算方法进行了比较研究。给出了计算公路建设全要素生产率的考虑成本函数的改进Divisia指数算法。最后应用公路建设产出效果和全要素生产率的计算方法进行了实证计算,验证了方法的可操作性和可靠性。更多还原

【Abstract】 In This paper, the economic basis of factor investment and factor productivity is firstly discussed, and relationships between investment, total factor productivity (TFP) and output growth are analyzed. On this basis, according to the history and the applicability of our country’s highway development, the author discusses the relationship of investment and output of highway construction and their relationship with total factor productivity (TFP). Then, the frame of a research method which compares highway construction output and total factor productivity (TFP) was presented. On the basis of this frame, a computing method of highway construction output effectiveness is conducted, and the condition this method is used is discussed. And a computing method of total factor productivity is also studied. The author designs a algorithm of the cost function of total factor productivity —Advanced Divisia index. Last, an example of how to compute the highway construction output effectiveness and total factor productivity is given, in this way, the maneuverability and the reliability of the method are tested.更多还原
