摘要:"美丽城市"作为"美丽中国"的重要组成部分，是我国生态文明体制改革创新的战略举措，也关乎人民群众对美好生活的追求，"美丽城市"建设的核心之一是提升生态环境和人居环境品质。使用203个地级以上城市2005-2017年的统计数据，在借鉴相关理论的基础上构建动态面板和联立方程模型展开实证研究。研究结果表明，城市EGI投资对城市经济发展有多重影响且在不同区域表现各异。在东部地区，EGI投资对经济发展有显著直接"拉动效应"，还通过全要素生产率、固定资产投资、第三产业和居民消费产生间接影响；固定资产投资、第三产业发展对EGI投资也有显著反馈作用；总体上东部地区的EGI建设与城市经济已初步达到"美丽"与"经济"的双赢。在中西部和东北地区，EGI投资和城市经济发展在许多环节存在"断链"，二者之间尚未形成良性互动。鉴于不同地区EGI建设对城市经济发展的影响机制存在较大差异，建议针对不同地区的薄弱环节和"断链"现象，因地制宜采取城市EGI发展策略，以实现最优资产利用，助推城市高质量发展。



Abstract:Implementation of beautiful China strategy calls for beautiful cities because they are not only the essential platforms of beautiful China but the innovation of ecological civilization. To realize the goals of beautiful cities, the government should increase public investments in urban environmental and green infrastructures (EGI). However, few literature have investigated the interactions between the EGI investments and urban economic growth. By studying of 203 cities in China using dynamic panel data analysis and simultaneous regression models, we examine the interactions between the EGI investments and urban economic growth across the country. The results indicate that the EGI investments have multi-level impacts on urban economic growth. Furthermore, the impacts of EGI investments vary disparately across regions. In eastern China, the EGI investments could influence urban economic growth both directly and indirectly via the proxies of fixed investments, service industries and residential consumption. Meanwhile, urban economic growth also has significant feedback influence on the EGI investments. However, in the other regions of China, the EGI investments and urban economic growth have not reached a virtuous cycle in most regions so far. Therefore, we suggested that policies of EGI investments should be adjusted according to the regional differences.
