生产性公共支出真的会改变产业集聚格局吗?——基于新经济地理的分析

Dose Productive Public Input Change the Distribution of Industrial Agglomeration Based on New Economic Geography?

本文在Pasquale,Ingrid和Petraglia(2007)基础上,构建了企业、家庭和地方政府三主体的新经济地理模型,分析了生产性公共支出对产业集聚的影响,发现生产性公共支出对地区产业集聚的影响分为"本地市场放大"效应和"挤出"效应;当满足突破条件时,外围地区的生产性公共支出的增加能打破长期均衡条件下的"中心-外围"结构。并在此基础上以1997-2009年中国省级面板数据实证上分析了生产性公共支出对中国产业集聚的影响,发现其对东部地区产业集聚的影响仍处在扩大的阶段,中西部地区生产性公共支出的增长力度还不足以打破现有的产业分布结构。

We built a three-agent new economic geography model based on the paper from Pasquale, Ingrid and Petragli productive public input. We a （2007） and analysed the impact on industrial agglomeration from found the effect on industrial agglomeration from productive public expenditure included two parts： Home Market Magnification effect and crowding-out effect. When it got the break-through condition, the increase of productive public expenditure from the edge could break the long-term equilibrium. Using a panel data from 1997 to 2009, we found the eastern industrial agglomeration effects are still in the expansion phase, the growth of productive public input is not enough to break the existing industrial distribution structure in the center and west region.
