摘　　要：本文采用我国1997-2009年省域面板数据,运用空间计量的研究方法,实证分析了技术创新、经济活动的空间集聚对区域碳生产率变化的影响。研究结果表明:我国区域碳生产率具有较强的空间相关性,采用空间计量的方法往往可以更好地解释我国区域碳生产率的空间变化;在影响因素方面,我国区域碳生产率主要受经济活动的空间集聚和产业结构的影响,技术创新的影响作用未能得到充分发挥;制造业的集聚不经济和产业结构低下是当前阻碍我国碳生产率增长的主要原因;从时间趋势上看,技术创新对提高我国区域碳生产率的作用在逐步增强,但在不同区域表现有所不同。因此,仅从技术创新的角度来提高碳生产率的努力往往事倍功半,必须着力优化产业结构和促成产业空间合理布局。基于此,本文提出了一些政策建议。Based on the annual provincial panel data from 1997 to 2009 in China, this paper employed a methodology of spatial econometric method and presented an empirical research about the influence of technological innovation and spatial agglomeration on the regional carbon productivity. The result shows that： the regional carbon productivity in China has a strong spatial correlation, the spatial econometric method has evidenced a better elaboration on the spatial change of the carbon productivity in China, and the main influential factors driving the change of regional carbon productivity in China are economic agglomeration and industrial structure. By contrast, the effectiveness of technological innovation has not fully performed. The diseconomies of agglomeration of manufacturing industry and low industrial structure are the main reasons which impede the increase of carbon productivity in China. From the point view of the time tendency, the influence of technological innovation on carbon productivity was becoming stronger, but it showed a different performance in different regions. Thus, the unilateral emphasis of the effectiveness of technological innovation on the carbon productivity improvement may have little effect. The efforts on the optimization of the industrial structure and industrial spatial distribution should be considered. Herein, some relevant policy recommendations are presented in this paper.
