首先针对产量因子调整、生态赤字与生态盈余指标与生态足迹实物量特性方面不足以及其实践应用中局限,分别构建生产足迹、污染物排放足迹、贸易足迹计算方法、生态可持续指数,对产量因子进行调整、推导最大可持续生产量、消费量的计算模型。其次应用方面与资源环境核算相连接,两者的共同点为生态足迹应用到资源环境核算上提供了可能,为彼此计算提供基础与拓展,比如根据资源环境核算计算生产足迹,也可根据生态足迹计算自然资源耗减与环境污染的计算方法,推导生态足迹的价值量核算模型等,进一步拓展生态足迹的应用范围与相关理论。最后对若干修正与扩展模型进行计算,构建完整的生态足迹指标体系,进行实证分析。
The ecological footprint theory was put forward in 1992, and because this method is simple, intuitive and easy to understand, it is recognized as a popular measure of sustainable development. A lot of research has been done into the correction and improvement of ecological footprint theory, but many aspects remain unresolved, including the calculation model, pollution footprint, trade footprint, and the value accounting model. Here, we discuss defects and inadequacies such as the adjustment of production factors, the characteristics of ecological deficits and ecological surplus indicators and ecological footprint physical quantity. We develop a calculation model for production footprint, pollutant footprint, trade footprint, maximum sustainable production and consumption, and ecological sustainable index. The model of the maximum sustainable production and consumption assumes that ecological footprint and ecological carrying capacity are equal, and therefore makes use of ecological carrying capacity and establishes a connection with resource environment accounting. We further analyzed the calculation of the industry footprint, intermediate product footprint, and final product footprint and consumer footprint, and government consumption footprint according to resource environment accounting, account natural resources and environmental pollution according to the ecological footprint. Operationally, the steps are: ( 1 ) calculate various types of land production footprint and ecological carrying capacity, (2) estimate the corresponding economic value according to each type of price, and (3) include all types of land economic value aggregation.
