不同类型的技术创新对产业国际竞争优势的影响——基于制造业面板数据的分阶段回归分析

Impact of Different Types of Technological Innovation on Industrial International Competitive Advantage:Regression Analysis Based on Panel Data of China′s Manufacturing Industries

构建线性回归模型,利用1996—2010年我国15个制造业行业的面板数据,根据消费者边际效用递减规律是否明显将样本行业分为最终消费品制造业和装备制造业,同时将研究区间划分为1996—2001年和2002—2010年两个阶段,分组、分阶段地对不同类型的技术创新(产品创新和工艺创新)对制造业国际竞争优势的影响进行实证分析。结果表明:产品开发类创新对产业国际竞争优势的巩固与保持具有显著的正向影响;性能改进类创新和工艺创新对产业国际竞争优势的影响取决于消费者边际效用变化的特点。

Dividing 15 manufacturing industries of China into two groups according to whether the law of diminishing consumer＇s marginal utili- ty is significant or not,namely final consumer goods manufacturing and equipment manufacturing industry, and dividing the research time interval into two periods,namely 1996-2001 and 2002-2010,this paper uses the panel data of China＇s 15 manufacturing industries to analyze empirically the impacts of different types of technological innovation（product innovation and process innovation） on industrial international competitive advantage from a utility perspective by the linear regression model. The results show as follows., product development innovation has a sustained significant positive impact on industrial competitive advantage the effects of performance improvement innovation and process innovation on competitive advantage depend on the characteristics of the change of consumer＇s utility.
