国内外投资对制造业技术进步影响的行业分化特征

Effects of Domestic and Foreign Investment on Technology Progress and its Differentiation Characteristics of Chinese Manufacturing Sectors

本文首先采用1996年-2008年中国制造业分行业数据,选择随机前沿生产函数模型测度了制造业各行业的全要素生产率变化率,通过调整得到技术进步率,在此基础上,利用2001年-2007年国内外投资的数据基于面板数据模型,研究了制造业各行业国内外投资对技术进步影响的问题,旨在揭示改革开放以来尤其是经济发展较快的最近几年制造业技术进步的源泉,并进一步探讨技术进步来源不同的两类行业的行业分化特征。实证结果表明,制造业绝大多数行业的技术进步来源于国内投资或外商投资,个别行业甚至同时受国内外投资的双重影响,当行业特征表现为市场竞争程度高且外商投资对国内投资比重偏高时,技术进步更倾向来源于国内投资,反之则更倾向来源于外商投资。

This paper firstly measures the change rate of total factor productivity of Chinese manufac- turing sub-sectors by using panel data from 1996 to 2008 in stochastic frontier production function model, and then gets technology progress through some adjustment. Based on this, we analyze the domestic and foreign investment effects on technology progress by using panel data from 2001 to 2007 in panel data model, in order to reveal the source of technology progress and furthermore investigate the features of these two types of sectors. The empirical study shows that technology progress originates from domestic or foreign investment in most sectors and even from both in several sectors. Sector technology progress tends to originate from domestic investment at a high competition level and also keeping a high propor- tion of foreign investment to domestic investment, and on the contrary it tends to originate from foreign investment.
