【摘要】：了解不同经济增长阶段环保投资呈现的波动特征,对实现环保投资与经济增长的协调发展尤为重要。文章通过构建分阶段阈值协整回归模型,分析了我国不同经济增长阶段,经济增长和产业结构对环保投资的差异性影响。同时,分析了环保投资与COD排放量在不同的经济增长阶段二者之间呈现的关联性影响。研究表明:我国环保投资随着经济周期的不同出现非线性波动;环保投资与经济增长的阈值效应发生在人均GDP增长率为9.01%处;我国产业结构对环保投资呈现负相关且正在转型与升级;总的来看,环保投资对COD呈现出反常的正相关性,即目前环保投资对COD减排并未实质性地推动作用。
[Abstract]:It is very important to understand the fluctuating characteristics of environmental protection investment in different economic growth stages, which is very important to realize the harmonious development of environmental protection investment and economic growth. This paper constructs a stepwise threshold cointegration regression model. This paper analyzes the different influences of economic growth and industrial structure on environmental protection investment in different stages of economic growth in China. This paper analyzes the relationship between environmental protection investment and COD emissions in different economic growth stages. The results show that: China's environmental protection investment has nonlinear fluctuations with different economic cycles; The threshold effect of environmental protection investment and economic growth occurs when the per capita GDP growth rate is 9.01%; China's industrial structure has negative correlation with environmental protection investment and is transforming and upgrading. On the whole, environmental protection investment has an abnormal positive correlation to COD, that is, environmental protection investment has not actually promoted COD emission reduction at present.

【正文快照】： 0引言随着经济的不断发展,环境污染日益严重。要不断适应经济可持续发展的新要求,就必须注重环境保护。而环境保护投资是环境保护的主要推动力。环保投资对经济增长的影响主要体现在两个方面:一是直接影响,环保投资通过环保产业的规模和效益直接带动了整个经济的发展;二是间接
