当今世界，蓝色经济已经成为全球海洋领域发展的重点，它强调的是海洋经济的可持续发展，突出国家间通过通力合作共同促进海洋资源开发与海洋生态环境保护。“21世纪海上丝绸之路”建设恰为中国与沿线国家的蓝色经济合作提供重要平台。从这一关系为切入点，研究沿线国家蓝色经济合作的驱动因素，构建包括国家战略发展、区域比较优势、政府政策导向、区域环境安全在内的蓝色经济合作领域选择依据，在考虑蓝色经济合作的一般领域的基础上，选择了资源能源、海洋产业、海洋科技、海洋生态环境作为中国与沿线国家合作的重点领域，并针对合作领域构建了以市场主导、陆海统筹、协作治理与利益协调为框架的合作机制。

In today's world, the blue economy has become the focus of global marine development policymakers. The economic sector emphasizes the sustainable development of the maritime economy as well as a cooperative mode of marine resource management and environmental protection among all seafaring nations. The 21st-Century Maritime Silk Road and Economic Belt is an important platform for cooperation on the blue economy between China and countries along the Belt. Against this backdrop, this paper looks into the driving factors behind this cooperation, including national strategies, regional comparative advantage, government policies and regional environmental safety. This study also examines energy resources, marine industries, marine technologies and the marine ecological environment as key areas for cooperation between China and countries along the Belt. Last but not least, this paper proposes a market-led, land-sea integrated and intergovernmental coordination mechanism which fosters communication and mediates the interests of all sides.
