基础设施供给、产业异质性与比较优势

Infrastructure Supply, Industry Heterogeneity and Comparative Advantage

本文在垄断竞争模型中讨论了地区基础设施供给与产业比较优势的关系,本文的理论模型分析表明,基础设施对产业比较优势的影响不仅受到地区基础设施供给数量的影响,也与产业的基础设施使用密集度密切相关。本文利用2007年中国135个部门的投入产出表的完全消耗系数刻画了制造业6类基础设施的密集使用度,并基于2005-2011年30个地区17个制造业数据对相关命题进行了经验研究,结果表明,电信、教育、科学研究和医疗卫生基础设施供给增加,对于相应基础设施密集使用产业的比较优势影响显著为正,而道路、电力基础设施对于比较优势的影响并不显著。本文的政策含义是,地方政府通过财政支出结构调整,增加教育、医疗卫生等民生类基础设施供给,有助于地区产业结构调整与产业升级。

This paper investigates how public goods supply affects industrial comparative advantage under the monopoly competitive model. Applying the input -output table of China＇ s 135 sectors in 2007, this paper surveys the intensity of use of 6 categories of manufacturing infrastructure. The empirical study using data of 17 industries in 30 regions between 2005 and 2011 concludes that an in- crease of infrastructure supply of such infrastructure as telecommunications, educa- tion, scientific research and public health has a significantly positive influence on the related industries＇ comparative advantages. Increased supply of roads and electricity infrastructures is not significantly influential of the comparative advan- tages. The policy implication of this paper is that the local government＇ s adjust- ment of the structure of infrastructure supply and added supply of such public goods as education and public health goods can effectively boost the local indus- trial restructuring and upgrading.
