我国环境保护投资与经济发展及COD排放关联研究

Research on the Association Relationship between Environmental Protection Investment and Economic Development and COD Emission

近些年来,我国环保投资一直保持较快增长,但变化波动较大,缺乏长期、稳定的资金来源渠道,尚未形成与经济发展之间稳定的联动机制。从总量上看,尽管环保投资与固定资产投资存在长期均衡关系,但是从增量上看,环保投资并非固定资产投资优先领域。环保投资对COD排放量存在一定影响,但由于投资结构的不合理,环境效益难以有效发挥。主要体现在:一定比重的城市环境基础设施投资与环境治理关系不密切;工业污染源治理投资规模一直偏低,难以发挥规模效应;建设项目"三同时"环保投资环境效益的实现存在较明显的时滞性。本研究基于以上分析,提出构建环保投资增长与经济发展的内生增长机制、优化环保投资结构、规划编制与实施应统筹考虑环境效益滞后因素等政策建议。

In recent years, environmental protection investment has been to maintain growth with the large fluctuations. It is lacking in long-term and stable funds channel, and has not yet formed a Stable linkage mechanism with the economic development. Accord ing to the total amount, there is a long-term equilibrium relationship between environmental protection investment and fixed assets investment, but according to the incremental amount, environmental protection investment is not in priority areas of fixed assets investment. Environmental protection investment has an impact on COD emission, but the environmental benefit is difficult to ef fectively play because of the irrational investment structure. There is a not close relationship between certain proportion of urban environmental infrastructure investment and environmental governance. It is difficult to play the scale efficiency withlow scale of in- dustrial pollution governance investment. The efficiency of new project ＂Three-Simultaneous＂ environmental protection investment usually lags. Based on the above analysis, this article makes suggestions. The growth mechanism is proposed to build between en vironmental protection investment growth and economic development. The structure of environmental protection investment is pro posed to optimized. Planning and implementation should be ~iven overall consideration of the la~ factor of environmental effieianev
