智库核心专家邓昭博士署名我智库在重要期刊APPLIED SPATIAL ANALYSIS AND POLICY发表论文Research on Port-Industry-City Integration and its Spatial Spillover Effects: Empirical Evidence from the Bohai Sea Rim Region，该文认为：

Port-industry-city is a primary carrier of high-quality economic development, and promoting the integration of port, industry and city is an important measure to realize port reform and industry-city integration. Based on the panel data of port-industry-city in the Bohai Rim region from 2012 to 2021, this study used the ITARA-EDAS model, ArcGIS spatial analysis tool and spatial Durbin model to explore the spatiotemporal evolution characteristics and spatial spillover effects of port-industry-city integration. The results show that: (1) The integration of port, industry and city in the Bohai Rim region has significant spatiotemporal differences, and the distribution pattern of "high in the south and low in the north" is more prominent, especially the gradient pattern with core cities as the center and key cities as the support. (2) The economic impact of port-industry-city integration in the Bohai Rim region has an agglomeration-diffusion effect, i.e., port-industry-city integration promotes the agglomeration of factors of production and promotes the growth of the local economy, which results in the restriction of the development of the neighboring regions; at the same time, port-industry-city integration accelerates the investment in the infrastructure of the neighboring regions through the extension of the industrial chain and its functions and leads to the inter-regional mobility of the production factors and regional cooperation. (3) There are significant regional differences in the direct and indirect effects of port-industry-city integration in provincial-level areas, and there are differences in the regression results with those in the Bohai Rim region. That is, the integration of port, industry and city in Liaoning and Shandong has a significant positive spatial spillover effect, while the economic impact of port-industry-city integration in the Tianjin-Hebei region has a diffusion boundary.（港产城是经济高质量发展的主要载体，推进港产城融合是实现港口改革和产城融合的重要举措。基于2012 - 2021年环渤海地区港产城面板数据，运用ITARA-EDAS模型、ArcGIS空间分析工具和空间Durbin模型，探讨了港产城一体化的时空演化特征和空间溢出效应。结果表明：(1)环渤海地区港、工、城一体化具有显著的时空差异，“南高北低”的分布格局更为突出，特别是以核心城市为中心、重点城市为支撑的梯度格局；(2)环渤海地区港产城一体化的经济影响具有集聚-扩散效应，即港产城一体化促进了生产要素的集聚，促进了当地经济的增长，从而制约了周边地区的发展；同时，港产城一体化通过产业链及其功能的延伸，加速了对周边地区基础设施的投资，促进了生产要素的跨区域流动和区域合作。(3)省域港产城一体化的直接效应和间接效应存在显著的区域差异，且回归结果与环渤海地区存在差异。即辽宁、山东地区港、工、城一体化具有显著的正向空间溢出效应，而津冀地区港、工、城一体化的经济影响具有扩散边界。）

据悉，Applied Spatial Analysis and Policy 是Social Sciences Citation Index (SSCI)期刊，影响因子为2，为公共政策研究的重要期刊。
