摘要
本文运用1996—2003年中国地区工业面板数据研究了自主研发、国外技术引进和国内技术引进对生产率的影响。在生产函数理论基础上,通过核算自主研发存量和国内外技术引进存量,运用一阶差分法和固定效应法,本文发现自主研发和国外技术引进对生产率有显著促进作用,但国内技术引进对生产率并没有显著影响。研究还发现,我国自主研发的吸收能力较低,阻碍了对引进技术的学习和消化,进而影响了生产率增长。自主研发、国外技术引进对生产率的影响也表现出明显的地区差异:自主研发只对东部和中部地区的生产率有显著正效应,而国外技术引进只对西部地区的生产率有显著正效应。各个地区不同的技术发展水平和创新能力基础可能是造成该现象的主要原因。
The paper is dedicated to probing into the effects of indigenous R＆D, foreign and domestic technology imports on industrial productivity across regions of China by using the province-level panel data from 1996 to 2003. Based on the expanded production function and calculating the stocks of R＆D and technology imports, the paper finds that indigenous R＆D and foreign technology import have significantly positive effects on productivity and domestic technology import have no significant effects on it by using fixed effects and first difference models. The paper also finds that the lower absorptive capacity of indigenous R＆D cumbers the productivity growth. The relationships among R＆D, foreign technology import and productivity also take on different patterns in different regions： R＆D has significantly positive effects on productivity only in central and east regions, while foreign technology import has significantly positive effects on productivity only in west regions. Different technical development and innovation capacity in different regions may be the main reasons of the phenomena.
