| Abstract: | The article conducts a research through theoretical carding, framework construction, and calculation path selection, and concludes that the contribution of ecosystems to human activities mainly comes from the ecological service function. Therefore, based on the relationship between the natural capital stock and flow, ecological services value (ESV for short) or eco-exergy services value (EEV) reflects the output capacity of ecological services. Regional ecological services value is connected to GDP through property ownership and main pressure sources. GDP or the ecological services value reflects the pressure of man-made capital on natural capital. The article attempts to use the ecological services value, eco-exergy services value, and GDP to construct the ecological service output capacity index (R) and pressure index (U), and by introducing the decoupling theory, it proposes a method to “return” the re-coupling GDP to a decoupling state and calculate the sustainable economic scale. It takes Ningdong Energy-Chemical Industry Base in Ningxia as the subject, and has three findings. Firstly, from 2007 to 2017, the economic development and ecological services were in a re-coupling state and the sustainable economic scale was 2.33×109 to 64.3×109 yuan, which was significantly lower than the total industrial output value in the corresponding year. Although the base deploys protection during construction, the R index began to decline after 2015, and there exists a risk of degradation. Secondly, the method uses the “declining turning point” of the R index to mark the bottom line, and attempts to put forward a quantitative method of regional sustainable economic scale from the perspective of the internal generation principle of the ecological contribution of capital value, which is helpful to the analysis method of reasonable population size, green GDP and ecological compensation. Thirdly, combined with the decoupling theory, the method can analyze the boundary of economic scale under regional ecological constraints, which has certain application value to enrich evaluations methods on sustainability. |
