摘要
本文通过构建一个中间产品种类扩张型的内生技术进步模型,探讨了开放经济条件下人力资本、国内研发与国外研发技术外溢影响经济增长的内在机理。对模型的竞争性市场均衡分析的基本结论是:技术吸收能力的提高、人力资本积累有利于长期经济增长,然而贸易开放度、技术水平差距对稳态增长率的影响效应具有不确定性。进一步的实证检验利用1996—2002年间我国30个省市的经济数据,考察了分别以人力资本、贸易开放度衡量的技术吸收能力对经济增长的影响,同时比较了进口贸易、外商直接投资这两类传递渠道的技术外溢效果,并就分析结果提出政策建议。
By building up a model of endogenous technical progress that increases types of intermediate products, we discuss the inner mechanism of the impacts on economic growth of human capital, domestic R&D and the spillover effects of foreign R&D in an open economy. In our equilibrium analysis on the model based on a competitive market, we conclude that while better capacity for technical assimilation and more accumulation of human capital facilitate long-term economic growth, the impacts of open trade and technical gaps on steady growth rates are uncertain. Economic data on 30 Chinese provinces and municipalities directly under the central government's control during 1996—2002 are used in further positive tests, to observe the impact of capacity for technical assimilation on economic growth from the perspectives of human capital and the level of open trade respectively. Comparisons are also made on two channels of dissemination of the effects of technical spillovers: import trade and direct foreign investments. Policy suggestions are made on the basis of the analysis.
