摘　　要：区域海洋经济发展不平衡是实现区域协调发展的重要障碍。文章基于机会不平等理论,利用Shapley值分解法获取机会不平等因素对区域海洋经济差异的贡献率,并探究机会不平等因素作用于海洋经济差异的多种渠道。结果表明:(1)从时空维度看,2012—2020年我国区域海洋经济差异的机会不平等指数呈现波动上升趋势。其中,南部海洋经济圈机会不平等指数较高,但近年来略有下降;东部海洋经济圈机会不平等指数较低且趋势变化不显著;北部海洋经济圈机会不平等指数位于前两者之间,但上升态势较为明显。(2)从来源因素分解看,国家级政策和对外开放因素对区域海洋经济差异的影响较大,而人才支撑、产业结构等因素的改善能有效缓解区域海洋经济差异。此外,对外开放因素显著影响北部和南部海洋经济圈区域海洋经济差异;东部海洋经济圈内部差异主要由国家级政策因素导致。(3)从影响渠道看,机会不平等因素可通过地方政策显著影响海洋创新投入等地方要素投入,进而造成区域海洋经济差异。在地方要素投入中,劳动力投入间接渠道主要影响南部海洋经济圈,海洋创新投入间接渠道主要影响北部和东部海洋经济圈。Unbalanced regional marine economic development is an important obstacle to the realization of regional coordinated development.Based on the theory of inequality of opportunity,this paper utilizes the Shapley value decomposition method to obtain the contribution rate of unequal opportunity factors to regional marine economic disparities,and explores the multiple indirect channels through which unequal opportunity factors act on marine economic disparities.The results show that:1)From the spatio-temporal dimension,the index of unequal opportunity of China's regional marine economic disparity showed a fluctuating upward trend in 2012-2020.The index of unequal opportunity was higher in the southern marine economic circle,but slightly decreased in recent years.The index of unequal opportunity was lower in the eastern marine economic circle,and the trend change was not obvious.The index of unequal opportunity in the northern marine economic circle is located in the middle of the former two,but the rising trend was more obvious.2)From the perspective of the source factor decomposition,national-level policies and the opening-up factor had a greater impact on the regional marine economic disparities,while the improvement of talent support,industrial structure and other factors can effectively alleviate the regional marine economic disparities.The opening-up factor significantly affects the regional marine economic differences in the northern and southern marine economic circles.The differences within the eastern marine economic circle are mainly caused by national-level policy factors.3)From the perspective of influence channels,unequal opportunity factors can significantly influence local factor inputs,such as marine innovation inputs,through local policy making,and thus cause regional marine economic differences.Among the local factor inputs,the indirect channel of labor inputs mainly affects the southern marine economic circle,and the indirect channel of innovation inputs mainly affects the northern and eastern marine
