摘要
利用中国1997年、2002年和2007年的投入产出表测算了中国27个制造行业的国际垂直专业化水平,并以面板数据模型检验了垂直专业分工对技术进步的影响,最后考察了垂直专业化对技术进步影响的行业差异性。研究结果表明:垂直专业化有利于制造业技术进步;与预期相反,研发投入对制造业技术进步带来一定的负面影响;低集中度、低开放度、高技术行业中垂直专业化对技术进步的促进作用更为明显。
This paper uses Chinese input-output tables in 1997,2002 and 2007 to measure the level of vertical specialization of China＇s 27 Manufacturing industries and estimate the effects of vertical specialization on technical progress based on panel data model,and at last we test the industry disparity of vertical specialization on technology advancement.The results show vertical specialization is positively associates with technical improvement in manufacturing industry sectors.Contrary to expectation,investment for RD brings about some negative influence on technical progress of manufacturing industry.The positive effect of vertical specialization on technical improvement in the low concentration industries,low openness,as well as high-tech industries is larger than that of high concentration,high openness and low-tech industries.
