长株潭三市生态足迹及其对经济增长的影响——兼论“两型社会”试验区生态建设方略

Effect of ecological footprint on economic growth of Chang-zhu-tang city cluster:Simultaneous comment on the ecological construction of "dual-model society" trial area

基于"两型社会"试验区长沙、株洲、湘潭三市1978—2010年度的面板数据,利用生态足迹修正模型,测算其生态足迹的年度变化规律,并将生态资源作为一种社会资本融入到社会生产函数中,利用经典的经济增长模型分析人力资本、实物资本、生态足迹等相关生产要素与经济增长之间的内在影响关系。结果表明:试验区中三个地区的生态足迹值相对较大,都呈现出递增的变化规律,能源生态足迹占生态足迹的比重相对较大,生态足迹和经济增长之间呈现正向关系,但这种变化规律在不同经济发展区域呈现出显著的地区差异性。

Based on panel data of Chang-zhu-tang ＂dual-model society＂ from 1978 to 2010, using ecological footprint model and classical economic growth model, the article analyzes the yearly changing rule of ecological footprint as well as the inner affecting relation between economic growth and productive factors for human capital, physical capital and ecological capital. This paper obtains the main results as follows： Ecological footprints in these three areas are very great, and all take on the changing rule of increasing by degrees; the proportion of energy ecological footprint in ecological footprint is comparatively big, and there is a positive relation between ecological footprint and economic growth, however, these effects take on a distinct differences among Changsha, Zhuzhou and Xiangtang city.
