基于随机前沿分析模型的我国海洋经济效率测度及其影响因素研究

A Study on the Marine Economic Efficiency and Its Influencing Factors in China Based on Stochastic Frontier Analysis Model

本文以2006-2014年中国沿海11个省市区面板数据为样本,运用联立方程的随机前沿模型对我国海洋经济的效率及其影响因素进行实证分析。研究发现,2006-2014年,我国海洋经济整体效率呈现出上升的趋势,但是仍然存在较大的提高空间;我国海洋经济发展是以资本密集型为导向,存在规模报酬递减规律;在三大海洋经济区域中,海洋经济年均效率值最高的是长三角洲地区,其次是环渤海地区和珠三角地区,其中环渤海地区追赶势头较明显;对外开放度对海洋经济效率的影响呈现U型非线性关系,区域海洋经济发展水平、海洋人力资源质量、海洋产业结构,以及海洋政策等对海洋经济效率表现为正向线性关系,但是海洋政策性因素的影响并不显著。

Based on the panel data of 11 provinces in China's coastal areas from 2006 to 2014,this paper makes an empirical analysis of the efficiency and influencing factors of marine economy in China by using the stochastic frontier model of simultaneous equations.The study found that during the period of 2006-2014,the overall efficiency of China's marine economy has shown an upward trend,but there is still room for improvement.The development of marine economy is capital-intensive oriented and obeys the law of decreasing returns to scale.In the three major marine economic zones,Yangtze River Delta region is of the highest marine economic annual average efficiency value,followed by the Bohai Rim region and the Pearl River Delta region,and the momentum of Bohai rim catching up with the Yangtze River Delta is more obvious.The influence of the open-door degree on the marine economic efficiency presents a U-shaped nonlinear relationship.The development level of regional marine economy,the quality of marine human resources,the industrial structure of the oceans and the marine policies are positively and linearly correlated with the efficiency of marine economy,but the impact of marine policy is not significant.
