以空间地理视角,验证了我国省域碳排放空间依赖性;基于空间面板数据模型,估计了不同视域影响因素对碳排放增长的贡献。研究发现:2000—2012年间,中国省域能源碳排放空间上具有依赖性,邻近省域的碳排放及影响因素的空间溢出效应明显;经济增长、金融发展、城镇化率、产业结构和出口依存度系数均为正值,人口、技术进步对降低碳排放增长作用效果显著,能源价格对碳排放增长作用效果没有通过显著性检验。政府部门在制定碳排放相关政策和发展规划时,必须考虑邻近区域碳排放影响因素的作用,结合碳排放及相关影响因素的空间溢出效应,实现中国在时间维度和空间维度的碳排放量整体降低。
From the spatial geographical perspective the spatial dependence of China’s provincial carbon emission was examined,and based on the spatial panel data model,the contribution of different influencing factors to carbon emission growth was estimated.It was found that there exists spatial dependence in China’s provincial energy carbon emission from 2000 to 2012,and the spatial spillover effects of neighboring provincial carbon emission and influencing factors are remarkable—the coefficients of economic growth, financial development, urbanization rate,industrial structure and export dependence are positive, the effect of population and technological progress on reducing carbon emission growth is remarkable,but the effect of energy price on carbon emission growth fails to pass the test of significance. In policy making and development planning, the government should take into account the effect of neighboring regions’ carbon emission,and integrate carbon emission and the spatial spillover effect of related influencing factors so as to reduce China’s carbon emission in both temporal and spatial dimensions as a whole.
