摘　　要：研究海岸带经济韧性与涉海企业全要素生产率(Total Factor Productivity,TFP)对推动海洋经济高质量发展具有重要意义。囿于涉海微观企业层面数据的缺乏,这一问题一直未得到定量化的探讨。为此,本文创新性地基于行业分类代码,在全国税收调查数据库中筛选出涉海企业并测算其TFP。同时,在定量评估沿海地区海岸带经济韧性的基础上,将两组数据进行匹配,实证考察了海岸带经济韧性对涉海企业TFP的影响效应和内在机理,得出以下结论:第一,2006-2021年,中国海岸带经济韧性总体呈现上升趋势,其中南部(福建、广东、广西和海南)海岸带经济韧性最强,东部(江苏、上海和浙江)其次,北部(辽宁、河北、天津和山东)最弱。在金融危机冲击时,南部海岸带经济韧性表现最好。在新冠疫情时期,东部海岸带经济则显现出更强的韧性。第二,地区海岸带经济韧性的增强,会促进涉海企业TFP的提高,其中的关键影响机制在于企业创新投入的增加。第三,市场化和数字化程度越高的地区,海岸带经济韧性对涉海企业TFP促进作用更加显著。Research on the resilience of the coastal zone economy(RCZE)and the Total Factor Productivity(TFP)of marine enterprises are crucial for promoting high-quality development of the marine economy.Due to the lack of micro-level data on marine enterprises,this issue has not been quantitatively explored.This paper innovatively processes national enterprise tax survey data based on industry classification codes to select marine enterprise data and calculate their TFP.Simultaneously,based on the quantitative assessment of RCZE in coastal regions,the paper matches the two datasets to empirically examine the impact and internal mechanism of RCZE on TFP of marine enterprises,yielding the following conclusions:First,from 2006 to 2021,China's RCZE generally showed an upward trend,with the strongest in the southern,followed by the eastern,and the weakest in the northern.During the financial crisis,the southern exhibited the strongest RCZE.During the COVID-19 pandemic,the east demonstrated greater RCZE.Second,the enhancement of RCZE in a region promotes the improvement of TFP in marine enterprises,with the key mechanism being the increase in enterprise innovation investment.Third,in regions with higher degrees of marketization and digitalization,RCZE more effectively enhances the TFP of marine enterprises.
