中国环境技术创新与经济增长实证研究

Empirical research on China's environmental technology innovation and economic growth

传统的技术创新对于中国经济取得的巨大成就功不可没,但在经济高速发展的同时,环境保护问题日益迫切。而环境技术创新则能够兼顾经济发展与环境保护。鉴于环境技术创新的重要性,文章分别以环境专利授权数、环境技术研发经费衡量环境技术创新产出和环境技术创新投入,运用中国2001-2012年省级面板数据对环境技术创新与经济增长的关系进行了实证检验。研究表明,环境技术创新投入与经济增长存在显著的正相关关系。研究还发现,中国各省区环境技术创新投入与产出差异明显,环境技术研发经费投入不足。同时指出中国环境专利制度尚不完善等问题,并提出了相应的对策建议。

Though traditional technology innovation is of great importance to the remarkable achievements for China＇ s economy, environmental protection problem is becoming more and more urgent in the high-speed economic development. It＇ s environmental technology innovation that can give attention to both economic development and environmental protection. In consideration of the importance of environmental technology innovation, environmental patent licensing and R＆D expenditures of environmental technology are used to measure the output and input of environmental technology innovation respectively in this paper. And the Chinese provincial panel data from 2001 to 2012 is used to make an empirical test on the relationship between environmental technology innovation and economic growth. Studies have shown that there is significant positive correlation between environmental technology innovation investment and economic growth. The studies have also shown that environmental technology innovation input and output is of great difference in China＇ s provinces and regions and the environmental technology innovation investment is significantly insufficient. Meanwhile it points out the imperfection of China＇ s environmental patent system and put forward the corresponding countermeasures and suggestions.
