经济集聚与我国收入差距研究

Research of the Economic Egglomeration and the Income Gap in China

本文以新经济地理学理论模型为基础,从经济活动的空间集聚角度分析产业集中、城市化综合水平及城镇化人口比率和收入差距形成的微观机制。通过我国1993年至2009年长达17年的数据分析,我们发现:经济活动在空间上的集聚对收入差距的影响作用机制具有正反两面性,即由于存在本地市场效应和前后向关联作用机制,产业集中、城市化综合水平的提高具有缩小收入差距的作用,而城镇化人口比率则在临界值范围以内具有扩大收入差距的趋势。我们认为,在采用政策的时候,应该考虑到政策的不同效应,甚至是正负两方面的效应,在扩大正面效应的时候,尽量抑制负面效应的产生。

This paper is based on the theory of the New Economic Geography model, take an analysis micro-mechanism of the formation on among the industrial concentration, urbanization integrated level, population ratios of urbanization and the income gap from the view of the spatial agglomeration of economical activity. We mainly found by 1993 to 2009 up 17 years of data analysis： the effect mechanism on income gap of the agglomeration of economic activities in space shows pros and cons of two sides, that is to say, because of the local market effect and the related effect-mechanism of forward and backward, the improvement of industrial concentration and urbanization integrated has played a role of reducing the income gap, while population ratios of urbanization has expanded the trend of income gap within critical value range. We believe that, when adopting policies, it should be taken into account the different effects of the policy, or even both positive and negative effects, when expanding the positive effect, suppressing the negative effects as far as possible.
