摘要
文章选取海洋经济发展指标,运用DEA-Malmquist指数模型测算2006—2018年我国11个沿海地区的海洋经济全要素生产率,探讨其时序变化以及变化来源,并进一步根据不同区域进行异质性分析。研究结果表明:我国海洋经济发展势头良好,全要素生产率平均提升4.811%,主要原因是技术进步,而技术效率的贡献较小;各沿海地区由于内外部条件不同,全要素生产率改善程度的差异较大,总体来看南部的表现优于北部;南部海洋经济圈的全要素生产率改善程度最高,其次是东部海洋经济圈,北部海洋经济圈最低。
By selecting marine economic development indicators and using DEA Malmquist index model to calculate the total factor productivity of marine economic development in 11 coastal areas of China from 2006 to 2018, this paper discussed the time series changes and sources of changes in total factor productivity of marine economic development, and further divided different regions for heterogeneity analysis. The research results showed that China′s marine economy had a good momentum of development, and the improvement of total factor productivity had increased by 4.811% on average during the study period. The main reason for the improvement was the progress of technical level, while the contribution of technical efficiency level was small.Due to different internal and external conditions in different provinces, the improvement of TFP in different provinces varied greatly. On the whole, the performance of southern provinces was better than that of northern provinces, the improvement of total factor productivity in the southern marine economic circle was the highest, followed by the eastern marine economic circle, and the northern marine economic circle was the worst.
