摘要
通过一个"新"新经济地理模型分析产业空间分布的动力机制,发现:除传统的集聚力(本地市场效应、价格指数效应)和分散力(拥挤效应)外,微观企业的选择效应是产业空间分布的"第四动力"。其作用路径:一是企业层面,给定外部竞争水平,效率异质性可能是"外围"高效率企业向"中心"集聚的"向心力",也可能是"中心"低效率企业向"外围"迁移的"分散力";二是区域层面,给定现有产业空间结构和外部竞争水平,较高的区域平均生产率门槛值促使低效率企业更趋于集聚,以通过"抱团效应"抵消竞争压力;三是产业层面,给定企业个体特征,产业内企业异质性初始程度和边际变化的作用方向是有差异的,既可能是集聚力,也可能是向心力。基于企业异质性的空间为产业份额和市场效率的双重"中心—外围"结构。
To understand the dynamics of spatial distribution of industries is key to optimize resource allocation of a country or a region. Analysis on the dynamics and mechanism of the spatial distribution of industries in a NNEG framework indicates that selection effect of firms are the "fourth" force besides home market and price index effect as agglomeration force and congestion effect as dispersion force. The work paths are as follows: Heterogeneity may be centripetal force to agglomerate firms with higher efficiency or TFP and disperse those lower ones in micro level, given the competition intensity; A higher MC threshold works as agglomeration force as it allows more low efficiency firm to survive in the big market in a regional level, given the spatial industry structure and the competition intensity; The original evenness of firms′ MC (k value) and its marginal change may work in a opposite direction, being centripetal or centrifugal. Space with heterogeneous firm could be dual "core-periphery" structure in the sense of industry share and productivity.
