本文用1999-2012年中国省级面板数据,研究了产业聚集对居民收入的影响及其区域差异。结果显示,在控制人力资本水平、资本投入、对外开放制度和非公有经济等条件下,产业聚集显著促进区域居民收入水平的提高;分区域比较分析表明,产业聚集对居民收入的影响存在区域差异:东部地区的产业聚集对区域居民收入的影响为正,而中西部地区的产业聚集对区域居民收入的影响为负。本文的政策含义在于:鼓励产业集群式发展,加大人力资本和资本投入力度,扩大对外开放,大力发展非公有经济,对于提高区域居民收入具有积极意义。
In this paper, we use Chinese provincial panel data from 1999 to 2012 to study the impact of industrial agglomeration on household income and its regional differences. The results show that under the condition of controlling the level of human capital, capital investment, opening up system and non-public economy, the industrial agglomeration significantly enhances the income level of residents in the region; the comparative analysis by subregion shows that there is a regional difference in the impact of industrial agglomeration on household income : The industrial agglomeration in the eastern region has a positive impact on the income of residents in the region while the industrial agglomeration in the central and western regions has a negative impact on the income of residents in the region. The policy implications of this article are: Encouraging industrial cluster development, increasing human capital and capital investment, expanding opening up to the outside world, and vigorously developing the non-public economy have positive implications for increasing the income of residents in the region.
