知识溢出是经济增长和产业集聚的重要因素。本文在新经济地理学自由资本模型中加入知识溢出,从而在考察第二天性的同时可以考察李嘉图比较优势对经济活动集聚的影响。文中重点区分了知识资本和物质资本,研究了知识溢出的“同源性”和“匹配性”。借助于数理分析和数值模拟,得出知识溢出效率与贸易自由度同时内生决定着经济活动的空间集聚;工业化率的提高并不会直接导致经济集聚,但市场开放度突破某个“门槛值”后则会加速经济集聚。工业化会加速区域经济的非均衡增长,解决问题的关键在于欠发达地区自主创业。提高知识溢出的效率能强化“产业梯度转移”效果。
Knowledge spillover is an important factor in economic growth and industrial agglomeration. This article adds knowledge spillover into the new model of free economic capital in economic geography, so that while examining the second nature, we can examine the influence of Ricardo’s comparative advantages on economic agglomeration. In this paper, the distinction between knowledge capital and material capital is focused, and the “homology” and “match” of knowledge spillover are studied. By means of mathematical analysis and numerical simulation, it is concluded that the knowledge spillover efficiency and trade freedom simultaneously endogenously determine the spatial agglomeration of economic activities; the increase of industrialization rate will not directly lead to economic agglomeration, but the market openness will break through a threshold Value “will accelerate economic agglomeration. Industrialization will accelerate the unbalanced growth of the regional economy. The key to solving the problem lies in the fact that the underdeveloped regions start their own businesses. Increasing the efficiency of knowledge spillover can strengthen the effect of ”industrial gradient transfer".
