| 本文在奈特经济框架下通过对生产服务业的均衡分析，在逻辑上推导出生产服务业比率时序稳定的结论，并利用世界投入产出数据库(WIOD)中40个经济体1996~2009年的560份投入产出表追踪数据，采用方差分析和一阶差分均值对0的t检验方法对生产服务业比率的时序稳定规律进行了经验研究，发现：服务业中间需求率、服务业增加值率、生产服务业对服务业增加值比率均在时序上稳定，从而为生产服务业聚类分析法与投入产出分析法的沟通提供一个方法论平台。 |

| This paper proves that the ratios of producer services are stable over sequential years by equilibrium analysis of the producer services in the Knightian economic framework. Based on 560 input-output tables from World Input-Output Database (WIOD) which cover the sequential data of 40 economies among year 1996 to year 2009, an empirical research is conducted by applying the quantitative techniques of analysis of variance of the original ratios and t-test of the means of the first-order differences against 0.The results show that the intermediate demand ratio and the value added ratio as well as the ratio of producer services to value-added of services product are stable over sequential years. Methodologically, the communication platform is provided between the approach of cluster analysis and the approach of input-output analysis in producer services research. |
