本报告基于2013～2022年上海与“一带一路”沿线63个国家的贸易和投资数据，采用综合指数法构建了上海服务“一带一路”建设贸易投资指数，系统考察了2013年以来上海与沿线各国的贸易往来和投资合作变化情况。研究表明：总体来看，十年间，上海服务“一带一路”建设贸易投资指数上升趋势明显，与沿线各国的贸易和投资合作持续深化；分维度看，贸易联通指数和投资合作指数总体上保持上升态势，贸易联通指数始终高于投资合作指数，且二者差距呈扩大态势；分区域看，东南亚地区的贸易投资指数明显高于其他五个区域，中东欧地区增速最快，而中亚地区则一直处于较低水平。未来，上海服务“一带一路”建设应合理统筹安全与发展，依托功能优势促进利益共享；加强制度创新，提升企业“走出去”积极性；坚持高水平对外开放，促进“一带一路”沿线六大区域协同发展。
Based on the trade and investment data of Shanghai and 63 countries along “the Belt and Road” from 2013 to 2022，this report takes the lead in constructing the trade and investment index of Shanghai supporting the construction of “the Belt and Road” with the comprehensive index method，and systematically examines the details of changes in trade exchanges and investment cooperation between Shanghai and countries along “the Belt and Road” since 2013. The research shows that，on the whole，the trade and investment index of Shanghai supporting the construction of “the Belt and Road” has shown an obvious upward trend in the past decade，and the trade and investment cooperation with countries along the line has continued to deepen；From a multidimensional perspective，the trade connectivity index and investment cooperation index have also overall increased，but the trade connectivity index has always been higher than the investment cooperation index，and the gap between the two is expanding；From a regional perspective，Southeast Asia’s economic and trade investment index is significantly higher than the other five regions，with the largest growth rate in Central and Eastern Europe，while Central Asia has been at a relatively low level. In the future，Shanghai’s construction of serving “the Belt and Road” should continue to be guided by serving the national strategy，reasonably plan security and development，rely on its own functional advantages to strengthen high-quality economic，trade and investment cooperation with countries along “the Belt and Road”，and promote the coordinated development of the six major regions along the Belt and Road.
