摘要
文章以新经济地理学TP模型为基础,将知识创新与扩散、地区间技术吸收效应与环境污染结合在一起,发展了动态的新经济地理学模型,不仅在分析方法上实现了新经济地理学不同模型的综合,而且得出的理论结论也实现了综合。从理论分析的角度,不仅分析了新知识的增长机理,而且探讨了知识异质性、地区间知识扩散强度、技术吸收效应与环境污染传播效应等因素对经济空间的演化、稳态以及区域福利动态变化的影响,对新经济地理学的理论结论作了重要发展,认为持续点与突破点的关系是任意的,持续点既可以大于突破点,也可以小于突破点,二者也可以相等,对称结构、中心—外围结构、一般的非对称结构都可能是稳定结构,在一定的贸易自由度范围内,中心—外围结构的稳定均衡可以与一般非对称结构的稳定均衡共存,这进一步论证了现实中多重均衡的经济地理景观,产业集聚与扩散的力量对知识分子与工人的福利水平的影响效果并不完全一致。
This paper develops a dynamic model of new economic geography by combining knowledge innovation and diffusion, interregional technology absorption effect and envi- ronmental pollution based on the new economic geography TP model. It realizes not only the synthesis of different new economic geography models in term of analysis method, but also the integration of theoretical conclusions derived in this essay. From the perspective of theo- retical analysis, not only does it analyze the growth mechanism of new knowledge, but also it discusses the effects of elements such as knowledge heterogeneity, intensity of inter- regional knowledge diffusion, technology absorption effect and environmental pollution spreading effect between regions on the evolution and steady state of economic space and the dynamic change of regional welfare and makes an important progress of the theoretical conclusions of new economic geography. This paper holds that the relationship of continu- ous point and breakthrough point is uncertain. The continuous point can be greater than the breakthrough point and be less than the breakthrough point, also they can be equal. The symmetrical structure, core-periphery structure and general asymmetric structure all could be stable structure. Within a certain scope of trade freeness, the stability of the core- periphery structure equilibrium can coexist with the stable equilibrium of general asymmet- ric structure, which further demonstrates the landscape of multiple economic geography equilibrium in reality, and also proves the incompletely consistent effects of the power of the industrial agglomeration and diffusion on the welfare of intellectuals and workers.
