Evaluation and Improvement of the Diffusion Coefficient and Inducing Coefficient——Considering the Effects of Value Added,Energy Saving and Emission Reduction

影响力系数和感应度系数是建立在投入产出表的基础上比较各部门拉动和推动作用的一种测算方法。本文在综合评价传统测算方法的缺陷、既有改进方法及其应用情况后,从经济效益、能源和环境效应出发,针对非竞争型投入产出表提出了相应的改进方法,采用世界投入产出表的中国2009年数据进行实证检验,比较系数改进前后计算结果的变化及其背后的经济含义,探讨兼具经济效益和节能环境效益的备选主导产业选择。研究指出在不同研究目标下影响力系数和感应度系数的计算公式具有较好的延拓性,本文的改进方法在经济结构转型时期具有较好的应用前景。

The diffusion coefficient and inducing coefficient based on the IO table are important measurements for comparing the pulling and pushing effects of different sectors. Some researchers have pointed out there were some defects in their traditional measurement,and improved them. After evaluating those method and application,this paper introduces a new measurement based on the non-competitive input-output table,which considers the effects of value added,energy saving and emission reduction. Then we take WIOD table of China in 2009 for example,examine the differences among those measurements by comparing the change of order and correlation coefficient,and choose the leading industries considering the economically beneficial and environmentally friendly effects. The results show that the new measurement provides a helpful analysis tool for the study of the structure transformation in China,and we can expand them on the purpose of different paths of development.
