Current studies mainly discuss the effect of overseas industrial parks from the perspective of institutional and cultural difference, multi-scale coupling, as well as key partnerships, while little attention has been paid to the comprehensive analysis of overseas industrial parks. Based on a theoretical framework, this paper explores the overall effect of China's overseas industrial parks from the geo-effects perspective by using field interviews and a case study approach. The research shows that:(1) the geo-effects reveal the over effect of overseas industrial parks from the multiple and complementary dimensions of geopolitics, geo-economics, geo-society and geo-culture;(2) the Cambodia Sihanoukville Special Economic Zone, as a flagship BRI project, has produced the prominent and positive geo-effects;(3) the institutional-economic-cultural-environmental adaptability of overseas industrial parks is becoming important. Overseas industrial parks must be rooted in the politics, economy, society, and culture of host country;embedded in local social networks;balance the rights and interests of all stakeholders;and form the community of interests, community of destiny, and community of responsibility with political mutual trust, economic integration, cultural inclusiveness, and social harmony. The paper not only deepens the understanding about the overall effect of overseas industrial parks, but also provides decision support and theoretical reference for government policy makers and the overseas investment of enterprises.展开更多

The phylogenetic relationships were analyzed based on three kinds of methods (maximum-likelihood, maximum-parsimony, and neighbor-joining), and the three topologies gained were basically similar. The results have showed that (1) a monophyletic Podocopida was supported strongly; (2) the phylogenetic relationships of four suborders were (Darwinulocopina plus (Bairdiocopina plus (Cytherocopina plus Cypridocopina))), which indicated that a close relationship between Cytherocopina and Cypridocopina, and Darwinulocopina had separated early from the main podocopinan; (3) Cypridocopinan formed a monophyletic group, among which the phylogenetic relationship of three superfamilies was (Cypridoidea plus (Macrocypridoidea plus Pontocypridoidea)).展开更多

Its formation and sediments record may be directly affected by the structural dynamics and the uplift of the Tibet Plateau. For this reason, we studied the mineral characteristics of the Maogou formation of Miocene sediments using X-ray diffraction (XRD) and scanning electron microscopy (SEM). The XRD results showed that quartz, chlorite, illite, calcite, plagioclase, orthoclase, kaolinite, and trace palygorskite are present throughout the sequence of the cross-section in Linxia basin. In contrast, gypsum and ankerite occur occasionally in the upper portion of the Miocene deposits. The content of calcite varied with layers in the profile and was relatively concentrated in mudstone. Chlorite and illite were observed transforming into palygorskite under SEM observation. Based on the mineral characteristics and the change of mineral composition, especially the clay minerals, it could be inferred that an arid environment prevailed in the region with warm and cold intervals during Miocene time.展开更多
