| 内容提要 | 本文从理论和经验两个方面系统探讨了“分”之利及其实现机制。研究发现:当产品差异化厂商具有线性需求函数和线性成本函数时，无论其进行产量竞争还是价格竞争，分割都能基于较高的产业同构程度对区域经济增长产生显著的促进作用，但是在产量竞争情况下，市场分割不利于总体经济增长，而在价格竞争情况下，市场分割能在有限的区间内促进总体经济增长。为了从经验上对此进行辨识，本文将“生产法”和“价格法”有机结合构建了主动型市场分割的全新样本，并通过面板数据变系数模型对数据进行处理，结果发现每一个省在产业发展方面至少拥有一个相对稳定的强劲对手，而由此造成的主动型市场分割也相对稳定并且可能与腐败密切相关，同时主动型市场分割对区域经济增长的促进作用将以产业同构为媒介并在一定程度上受制于开放程度和经济周期，因此降低区域间产业同构是消除分割，实现市场一体化的唯一有效途径。 |
| Abstract | This paper analyzes the effect of segmentation from both theoretical and empirical perspectives. It is found that under competition among heterogeneous producers with linear demand and cost function, market segmentation will accelerate regional economic growth through high industrial similarity. But under production competition, market segmentation will do harm to the whole economy. While under price competition, market segmentation will do good to the whole economy in a limited scope. In order to measure the effect of active segmentation on growth, we combine “Production Method” and “Price Method” to construct a new sample, based on which the panel data are processed by virtue of varying coefficient models. We find that every province has at least one strong stable competitor in industry development and the active segmentation which may has close relationship with corruption is also very stable. What’s more, active segmentation will accelerate regional economic growth through the media of industrial similarity, which is constrained, to some extent, by opening policy and business cycle. So reducing industrial similarity is the only path to eliminate segmentation and realize market integration. |
