| 摘要：本文从产品空间理论出发，运用2002－2018年中国海关产品出口数据，刻画了成渝地区双城经济圈比较优势演化规律，并从区域和产业层面实证检验成渝地区产品密度与产业升级之间的关系。研究结果表明：（1）成渝地区内部产业协同化发展，优势产业接近但优势程度不同，四川优势产业更密集，重庆优势产业专业化程度更高；（2）成渝地区总体遵循比较优势发展规律，产品密度较高，具备一定高技术产业基础，但区域内部产业发展不均衡；（3）产品密度对产业升级具有显著正向作用，且更能促进产品保持比较优势。本文认为未来成渝地区双城经济圈应在政府引导和市场协调的作用下，沿比较优势逐步向高技术产业跳跃，选择差异化协同路径，创新驱动产业转型升级。 |

| Abstract：Starting from the product space theory and using the export data of China Customs from 2002 to 2018，this paper depicts the evolution of the comparative advantages of the Chengdu-Chongqing Twin Cities Economic Circle，and empirically tests the relationship between product density and industrial upgrading in Chengdu-Chongqing from the regional and industrial levels.The results show that：(1) the coordinated development of internal industries in Chengdu and Chongqing，the advantageous industries are close but the degree of advantages is different，the advantageous industries in Sichuan are more dense，and the advantageous industries in Chongqing have a higher degree of specialization；(2) Chengdu-Chongqing region generally follows the law of comparative advantage development，has high product density，and has a certain high-tech industrial foundation，but the development of industries within the region is uneven；(3) Product density has a significant positive effect on industrial upgrading，and can promote products to maintain comparative advantages；(4) In the future，under the guidance of the government and the role of market coordination，the Chengdu-Chongqing Twin Cities Economic Circle should gradually leap to high tech industries along its comparative advantages，choose a differentiated and collaborative path，and drive industrial transformation and upgrading through innovation. |
