本文分别选取参数、半参数与非参数方法中的ATFP法、LP法和DEA法对中国制造业15个子行业的全要素生产率进行了测算及比较,并利用投入产出法计算了产业间R&D溢出,对国际贸易和FDI渠道下的R&D资本溢出进行了衡量。以2000--2009年中国制造业的面板数据为样本实证检验了R&D溢出对全要素生产率的影响。其结果发现:产业间、国际贸易与FDI渠道下R&D溢出对行业全要素生产率均存在显著的正效应,行业自身R&D投资却具有一定的抑制作用。比较三种全要素生产率的测算方法,ATFP法得到的生产率数值存在明显的偏误,而LP和DEA法的测算和估计结果较为一致,能够保证实证结论的稳健性和有效性。
ATFP of Parametric Method, LP of Semi-parameter method, and DEA of non- parametric method are respectively used to measure the total factor productivity (TFP) in 15 sub-sectors of manufacturing industry of China. R&D spillover effects through inter-industry are calculated by Input-Output method, and R&D spillover effects through international trade and FDI are also measured. And the influence of R&D spillover effects on total factor productivity is testified empirically with panel data of Chinese manufacturing industry from 2000 to 2009.The results show that: R&D spillover effects through inter-industry, international trade and FDI all have a positive effect on TFP, while R&D investment in the industry has an inhibitory effect. Comparing the three method of measuring TFP, ATFP method has an apparent bias error in measuring TFP, while TFP values of LP method and DEA method are almost consistent, assuring the robustness and validity of the results.
