以吉林省为例,采用无残差完全分解方法和柯布-道格拉斯生产函数,分别提取环境变化和经济增长的驱动因子,在分析共同影响因子对环境系统和经济系统作用差异的基础上,应用异速生长模型分析经济子系统和环境子系统的相对变化关系.结果表明:经济增长和环境变化具有不同的增长维度,环境变化中的规模效应依赖于经济系统中资源要素的投入水平,而驱动经济增长的技术变化因子仅仅是引起环境变化技术效应的一个方面,环境系统的技术变化具有一定的独立性;经济增长和环境变化既有关联性也有差异性,经济系统主导形成二者倒"U"型的数量关系,而环境系统影响因子进一步决定了在何种污染程度上穿越环境高山;环境变化和经济增长的相对速率具有广义分维性质,环境系统和经济系统的负异速生长是实现可持续发展环境目标的根本途径.
以吉林省為例,採用無殘差完全分解方法和柯佈-道格拉斯生產函數,分彆提取環境變化和經濟增長的驅動因子,在分析共同影響因子對環境繫統和經濟繫統作用差異的基礎上,應用異速生長模型分析經濟子繫統和環境子繫統的相對變化關繫.結果錶明:經濟增長和環境變化具有不同的增長維度,環境變化中的規模效應依賴于經濟繫統中資源要素的投入水平,而驅動經濟增長的技術變化因子僅僅是引起環境變化技術效應的一箇方麵,環境繫統的技術變化具有一定的獨立性;經濟增長和環境變化既有關聯性也有差異性,經濟繫統主導形成二者倒"U"型的數量關繫,而環境繫統影響因子進一步決定瞭在何種汙染程度上穿越環境高山;環境變化和經濟增長的相對速率具有廣義分維性質,環境繫統和經濟繫統的負異速生長是實現可持續髮展環境目標的根本途徑.

Applying the methods of the non-residual decomposition model and Cobb-Douglas production function,the factors driving environmental changes and economic growth were extracted.The allometric growth law was used to analyze the relative dynamic relationship between economic and environmental subsystems in Jilin Province based on the analysis of the differences in the effects of factors on environmental and economic systems.The results showed that economic growth and environmental changes presented different growing dimensions.The scale effects on environmental changes depended on the input level of resource elements in economic systems.The technical factor driving economic growth was only one of the factors preventing environmental deterioration,and the technical change of environmental system was independent to a certain extent.There were both correlations and differences between economic growth and environmental changes.Economic systems resulted in a reverse "U" quantitative relationship between economic growth and environmental changes,while environmental factors determined on which pollution level environmental systems could get across the "environmental mountain". The relative rate of environmental changes and economic growth was characterized by a generalized fractal dimension.The negative allometric growth between environmental changes and economic growth is the fundamental way to achieve the objective of sustainable development.
