摘要
本研究选取1985年~2007年江苏省的生态足迹、经济数据,构建生态足迹消耗与人均收入、经济结构变量的计量模型,对江苏省经济增长与资源消耗之间的关系进行了实证研究。研究结果表明:①江苏省的资源消耗量与经济增长在实际取值区间呈"倒U"型曲线关系,二者的演化规律基本符合库兹涅茨曲线的特征;②经济结构变量对生态足迹消耗以及生态足迹与收入曲线产生影响,固定资产投入比例、城乡收入差距、城镇居民人均可支配收入增长率的提高会加大资源的消耗量,并刺激经济增长对资源的需求,促使生态足迹与收入曲线更加陡峭,相反,产业结构的升级则缓解了经济增长过程中资源的压力。
The relationship between resource consumption and economic growth has drawn much attention from the fields of ecology and economy. The authors adopted an ecological footprint methodology to further explore the relationship in this work. We formulated a series of methods and indicators, like ecological footprint consumption, per capita income and economic construction, on the basis of data regarding ecological footprint and economy in period 1985-2007 to exam the relationship between economic growth and resource consumption. Results indicated that: 1) the relationship of ecological footprint and economic growth generally follows the characteristics of the Kuznets Curve, i.e., with an increase in per capital gross domestic product (GDP), the consumption of resources begins to rise constantly until reaching a certain level. Then, it declines; 2) in the processes of economic development, the changes in economic structure variables will impact resource consumption. Increases in the proportion of fixed asset investments, the income gap between the urban and rural areas, the growth rate of the disposable income per capital for city residents can basically accelerate the resource consumption and stimulate a requirement for resources for economic growth. On the contrary, an upgrade for industrial structure can alleviate the pressure on resource consumption to some extent; 3) the changes in economic structure variables also impact the relationship between ecological footprint consumption and per capita income. It was also found that increases in the proportion of fixed asset investments, the income gap between the urban and rural areas, and the growth rate of the disposable income per capital for city residents can speed up a conversion of farmland to other land use types and stimulate a demand for non-agricultural land, thereby resulting in a steeper slope of the curve illustrating the relationship between ecological footprint and income. The upgrade for industrial structure can make the curve relatively flatter. In practice, if others variables keep invariant, we may take a series of effective measures, for example, optimizing industrial and investment structures, guiding appropriate consumption of residents, improving the efficiency of economic growth, and narrowing the income gap between urban and rural areas, to lessen resource pressures brought by sustained economic growth.
