Research progress and prospects of digital restructuring of global-local interactions北大核心CSCD

Global-local interaction is an important research topic in economic geography. In recent years, the rapid development of digitalization in various countries and regions has profoundly affected the global production and trade networks. However, there is a lack of systematic theoretical discussion on digitalization and global-local interaction studies. The objective of this study is to conceptually rethink the role of digitalization in reshaping global-local interactions from a dynamic and relational perspective. To do this, the study first systematically reviewed the digital turn in economic geography and discussed the rethinking of digitalization. It is found that the understanding of digitalization is gradually moving beyond the limits of isolated, static, and passive technocentric approaches and towards a more dynamic, relational, and open perspective. Second, the study combined the "digital turn" with the "relational turn" in relational economic geography, which constructs theoretical bridges between digitalization and global-local studies. Third, this study provided a basic understanding for sorting out the evolution of the research frameworks, that is, from the global value chain (GVC) to the global production network (GPN) and then to the digital ecosystem (DE). We argued that digitalization has been deeply involved in shaping the global economic landscape, restructuring global-local production relations, and reconstructing regional development. Based on this recognition, we discussed the primary performance of digitalization on the restructuring of global-local interaction from three aspects: enterprise relationship, spatial effect and interaction mechanism. Finally, grounded in the practice of China's urban and regional digital economy development, the possible theoretical innovations and prospects for future research on digitalization and global-local interaction in the Chinese context were proposed. The study pointed out that we can integrate the regional practices of China's digital development with more in-depth research from the perspectives of the platform ecosystems, spatial effects, location analysis, local development models, and so on in future research. © 2023, Editorial office of PROGRESS IN GEOGRAPHY.

甘肃文县阳山金矿床葛条湾-安坝矿段原生晕地球化学特征及深部找矿远景评价

甘肃文县阳山金矿是产于勉略缝合带内的超大型卡林-类卡林型金矿床.为探讨矿区深部找矿潜力和成矿远景评价,文章对葛条湾-安坝矿段30号勘探线剖面的成矿及伴生元素原生晕地球化学特征进行研究,结果表明:该矿段原生晕的轴(垂)向分带序列自上而下为:Pb—Co—Cu—Zn—Mn—Bi—Mo—Sb—Au—As—Ag.矿体中部原生晕具...     

时空演变视角下海南游艇旅游发展影响因素研究

为促进海南游艇旅游转型升级与空间布局优化，推动海南海洋经济高质量可持续发展，本文基于2013年、2017年、2021年海南游艇俱乐部、游艇会及游艇码头数据，利用标准差椭圆分析、平均最近邻指数、核密度分析、重心迁移模型对海南游艇旅游的时空演化特征进行研究，并利用近邻分析法、相关性分析法和政策文本分析法，从旅游资源禀赋、自然地理环境、区位交通条件、政策保障机制等四个维度剖析和阐释海南游艇旅游时空演化特征的影响因素。研究发现：（1）海南游艇旅游核心场所持续增加;（2）海南游艇旅游发展呈显著的空间聚集特征，聚集程度先上升后下降;（3）海南游艇旅游呈东北-西南走向迁移布局;（4）海南游艇旅游模式逐渐由“三亚-海口双核心”向“三亚单核心”演变;（5）自然地理环境和旅游资源禀赋是影响海南游艇旅游时空格局形成的基础性因素，区位交通条件是其时空演化特征的驱动性因素，政策支持是其时空演化形态的导向性因素。最后，对海南游艇旅游可持续发展提出四个方面的对策建议，以积极推动具有世界影响力的中国特色自由贸易港建设。
