本文采用生态足迹理论方法对鄱阳湖地区6个城市(南昌、景德镇、九江、新余、鹰潭、抚州)1991-2010年生态足迹进行了测算,以生态足迹度量生态资源投入,与劳动力、资本一起作为投入要素对经济增长的内在贡献度进行了分析,并研究了全要素生产率与经济增长率的关系以及三大产业对生态足迹的影响。结果表明:(1)1991-2010年鄱阳湖地区6个城市生态足迹呈现逐年上涨的趋势,其中化石能源地、耕地与草地的生态足迹对总生态足迹的影响较大;(2)生态资源、劳动力与资本等要素对经济增长的贡献度呈现出地区性的差异,南昌、九江、新余和鹰潭属于资本主导型,资本对经济增长的贡献率最大,景德镇和抚州属于劳动力主导型,劳动力对经济增长的贡献率最大,生态资源要素的贡献率在6个城市中均居于最后,说明生态资源要素的使用效率过低;(3)全要素生产率对经济发展水平起到了关键作用,但6个城市的全要素生产率总体水平都很低,说明鄱阳湖地区经济增长的技术含量较低,要素的使用属于粗放型,这不利于该区域经济长期快速发展的要求;(4)第一产业对生态足迹的影响最大,第三产业对生态足迹的影响最小,鄱阳湖地区各城市应转变经济发展方式,大力发展第三产业。最后,在此基础上提出了鄱阳湖地区可持续发展的对策。
In this paper, the ecological footprint of six cities (Nanchang, Jingdezhen, Jiujiang, Xinyu, Yingtan and Fuzhou) in Poyang Lake region was estimated from the ecological footprint theory in 1991-2010. The ecological footprint was used to measure the ecological footprint, together with the labor force and capital Input elements analyze the intrinsic contribution of economic growth and study the relationship between total factor productivity and economic growth rate and the impact of the three industries on ecological footprint. The results showed as follows: (1) The ecological footprint of six cities in Poyang Lake area increased year by year from 1991 to 2010. Among them, the ecological footprint of fossil fuels, cultivated land and grassland had a greater impact on the total ecological footprint. (2) The contributions of labor force and capital to economic growth show a regional difference. Nanchang, Jiujiang, Xinyu and Yingtan belong to the capital-led type. Capital contributes the most to economic growth. Jingdezhen and Fuzhou belong to the labor-led type. Labor-to-economy The contribution rate of ecological resource elements is the last in all six cities, indicating that the efficiency of using ecological resource elements is too low. (3) Total factor productivity plays a key role in the economic development level. However, six cities The overall level of total factor productivity is very low, indicating that the technological content of economic growth in Poyang Lake is low and the use of factors is extensive, which is not conducive to the long-term rapid economic development in the region; (4) The tertiary industry has the least impact on the ecological footprint. All cities in the Poyang Lake region should change the economic development mode and vigorously develop the tertiary industry. Finally, based on this, the countermeasures of sustainable development in Poyang Lake area are put forward.
