| 摘要: |
| 实现海洋强国战略离不开海洋经济高质量发展，而创新是驱动高质量发展的重要动力。文章基于2008—2020年沿海地级及以上城市的面板数据，运用双重差分法和中介效应模型实证检验海洋经济发展试点政策对城市创新能力的影响。研究结果表明，海洋经济发展试点政策显著提高了城市创新能力，并通过了一系列稳健性检验。异质性分析表明，海洋经济发展试点政策在中、南部经济圈，经济增长压力较小的城市以及科教水平较高的城市中呈现显著促进作用。机制检验结果显示，海洋经济发展试点政策通过人才和企业的集聚效应增强了城市创新能力。文章不仅为海洋经济发展试点政策所形成的经济后果提供了经验证据，还为提升城市创新能力、推动海洋经济高质量发展提供了政策启示。 |

| Abstract: |
| Building China into a maritime power is inseparable from the high-quality development of the marine economy, and innovation is an important driving force for high-quality development. Based on the panel data of coastal cities at and above prefecture-level from 2008 to 2020, this paper empirically examines the impact of marine economic development pilot policies on urban innovation ability by using the difference-in-difference method and the mediating effect model. This paper shows that marine economic development pilot policies significantly improve urban innovation ability and pass a series of robustness tests. Heterogeneity analysis shows that marine economic development pilot policies present a significant promotion effect in the central and southern economic zones, cities with less pressure on economic growth, and cities with higher levels of science and education. The mechanism test shows that marine economic development pilot policies enhance the city's innovation ability through the agglomeration effect of talents and enterprises. This paper not only provides empirical evidence for the economic consequences of marine economic development pilot policies, but also provides policy insights for enhancing urban innovation ability and promoting the high-quality development of the marine economy. |
