| 摘 要： | 面对长三角地区区域一体化的经济建设及绿色发展新需求,生态创新如何影响该区域生态经济发展水平,学术界尚未形成共识。本文基于2010—2018年长三角地区41个地级及以上城市面板数据,首先,研究了生态创新对生态经济发展的线性影响;然后,运用中介效应模型考察了生态创新对长三角地区生态经济发展的影响途径;最后,使用面板门槛模型,探索了异质性收入水平下,生态创新与生态经济之间的非线性关系。研究结果表明：①生态创新促进了长三角地区生态经济的发展;生态创新通过提升绿色技术扩散,而非绿色技术进步来推动长三角地区生态经济发展;②生态创新在不同收入水平下存在双门槛效应,即随着收入水平的上升,生态创新对生态经济发展的影响显著为正,而且其影响程度呈现出先递增后递减的非线性规律。本文建议应从提升生态技术创新能力、防止“一刀切”政策以及加强区域合作等方面来促进长三角地区生态创新一体化,从而助力该区域经济高质量发展。 |

| Abstract: | The economists have not yet reached a consensus on whether and how ecological innovation affects the development of ecological economy. This study explored the relationship between ecological innovation and ecological economy based on a panel data set of 41 cities in the Yangtze River Delta region covering the period 2010-2018. We first explored the impact of ecological innovation on ecological economy with a linear regression model, and then investigated the ways by which ecological innovation took effect by using a mediation effect model. Finally, we tested the nonlinear relationship between ecological innovation and ecological economy based on a panel threshold model. The results show that ecological innovation has significantly promoted the development of ecological economy in the Yangtze River Delta region, which is mainly driven by the improvement of green technical diffusion. In addition, ecological innovation has a significant double threshold effect on ecological economy, that is, the degree of influence of ecological innovation first increases and then decreases with the increase of income level. In order to promote the high-quality economic development of the region, we suggest that the integration of ecological innovation in the Yangtze River Delta region should be promoted from several aspects, such as improving the ability of ecological technology innovation, preventing the “one size fits all” policy, and strengthening regional cooperation. |
| Keywords: | ecological innovation ecological economy green technology diffusion green technology progress panel threshold model Yangtze River Delta |
