摘要
本文构建了二级三要素CES生产函数,把要素投入分为R&D投入与非R&D投入两个部分,计算了重庆第三产业五个主要行业的R&D投入与非R&D投入的替代弹性和产出弹性。研究发现这些行业目前都处于规模报酬递增阶段,人力投入与资本投入之间的替代弹性平均约为1,R&D资本投入替代弹性比R&D人力投入替代弹性小,非R&D投入的产出弹性高于R&D投入的产出弹性。最后根据研究结论提出了对策建议。
A two- level and three-factor CES production function is established, the input factors are divided into R＆D input and non - B＆D input, and the elasticity of productivity and substitution elasticity of the R＆D input and non - R＆D input on the five major sectors of tertiary industry in Chongqing are calculated. It is found that these industries are in the stage of increasing returns to scale, the substitution elasticity between human input and capital input is about one, the R＆D capital＇ s substitution elasticity is smaller than that of R＆D manpower, the non - R＆D input＇ s elasticity of productivity is higher than that of R＆D input. In the last, based on the results, brief policy suggestions are proposed.
