中文摘要：构建包含海洋与内陆城市的双区域DSGE模型,引入要素流动成本差异、沿海城市对内陆城市的技术溢出、陆海中间品互补以及沿海出口导向机制,研究双循环格局下陆海经济协同发展机制。研究表明,降低内陆要素流动成本、强化沿海技术溢出效应、优化陆海区域产业互补格局,可显著缩小区域发展差距。外需冲击短期促进陆海协同,长期需依托技术与要素流动的优化,防范陆海区域经济发展失衡。技术溢出与要素流动成本对区域差距具有调节效应。基于此,提出降低内陆要素流动成本、强化沿海技术溢出传导、优化陆海产业互补格局、化解外需冲击风险和实施差异化货币政策等建议,为落实陆海统筹、畅通双循环新发展格局与实现共同富裕提供理论依据与政策启示。

外文摘要：This paper constructs a dual-region DSGE model including ocean and inland cities,and introduces the cost difference of factor flow,technology spillover,complementary intermediate products and coastal export-oriented mechanism to study the coordinated development mechanism of land and sea economy under the dual-cycle pattern.The research shows that reducing the cost of inland capital flow,strengthening coastal technology spillover and optimizing regional industrial complementarity can significantly narrow the regional development gap;The impact of external demand will promote the cooperation between land and sea in the short term,and it is necessary to rely on the flow of technology and factors to prevent the imbalance of economic development in land and sea areas in the long term.Based on this,this paper puts forward some suggestions,such as reducing the cost of inland factor flow,strengthening the spillover conduction of coastal technology,optimizing the complementary pattern of land and sea industries,resolving the impact risk of external demand and implementing differentiated monetary policy,which provides theoretical basis and policy enlightenment for implementing the new development pattern of land and sea planning,realizing common prosperity and smooth double circulation.
