改革开放以来,随着我国经济建设的大力发展和我国综合国力的不断提高,对海洋经济的战略性作用越发重视,于2013年提出"21世纪海上丝绸之路"战略.文章采用产业结构合理化和高级化这两个指标来衡量产业结构,进而构建海洋生产函数,将产业结构合理化和高级化引入生产函数,运用固定效应模型分析产业结构合理化和高级化的指标对海洋经济增长的实证影响.研究表明:海洋经济增长不仅取决于资本与劳动的投入,而且产业结构优化对海洋经济增长的贡献显著.虽然产业结构高级化指标对海洋经济有显著正的影响,但是产业结构合理化指标对海洋经济的影响为负且不太显著.这证明我国海洋经济产业间要素流动不自由,因而政府要加强消除海洋产业间要素自由流动的障碍力度.同时还发现海洋经济具有规模经济效应,因此大力引导资本和劳动力进入海洋经济是促进海洋经济增长的主要手段,尤其是从那些已经产能过剩的产业,以此来帮助我国经济转型.%Since the Reform and Opening Up,with the vigorous development of economic con-struction and the increasingly improvement of comprehensive national strength in China,the stra-tegic role of marine economy has arisen more and more attention,putting forward the "Twenty-first Century Maritime Silk Road"strategy in 2013.In this paper,two indicators of industrial structure rationalization and optimization measure of industrial structure,were used to construct the function of marine production,the industrial structure rationalization and optimization is in-troduced into the production function,using fixed effect model analysis of industrial structure ra-tionalization and optimization of the index effect on empirical marine economy growth.The study showed that marine economic growth is not only determined by the input of capital and labor,but also the contribution of industrial structure optimization to the growth of marine economy. Though,the industrial structure has a significant impact on the marine economy,the impact of the industrial structure on marine economy is negative and not significance.It was proved that the flowing of the elements of the marine economy in China is not free,so the government should make efforts to eliminate the obstacles of the free movement of the marine industries.At the same time,the paper also found that the marine economy has scale economy effects,so it is the main means to promote marine economic growth by guiding capital and labor into the marine economy, especially from those who have excess capacity in the industry,in order to help China's economic transformation.
