The Chinese government has provided various forms of assistance to the Tibet Autonomous Region and has substantially improved their facilities, which has had a positive influence on the development of tourism in Tibet. The present study investigated how assistance to Tibet (AT) coordinates with tourism development (TD) by exploring the patterns and influencing factors of AT and TD using statistical data from 74 prefectural units from 1991 to 2015. The findings led to several conclusions: (1) AT displayed strong and constant coupling interactions with TD, and the coupling coordination degree increased from moderately unbalanced development (MUD) to barely balanced development (BBD). However, the coupling coordination degree remains low (MUD) in most prefectural units; (2) in 2015, the degree of coupling coordination displayed a “core-periphery” spatial pattern (i.e., low in center and high in the periphery), which highly coincides with the patterns of AT (x) and TD (y), and should thus be improved further; and (3) both AT factors and TD factors have significant effects on the spatial differentiation of coupling coordination degree but not on the coupling degree. This study expands research on coupling coordination and AT and provides scientific guidance for further coordinating AT and TD.
e purpose of this paper was to systematically investigate the influence of acid rain environments on the seismic behaviour of a reinforced concrete (RC) column. Six RC column specimens with shear span ratios of 2.84 were tested under low cyclic reversed loads after being subjected to accelerated corrosion tests in an artificial climate. e corrosion level and stirrup ratio were used as the control variables. e corrosion ratios of the longitudinal rebars ranged from 0 to 13.17%, and the corrosion ratios of the stirrups varied from 0 to 6.75%. e seismic behaviours of the column specimens were analysed with respect to visual damage, failure mode, hysteresis behaviour, load-carrying capacity, deformation capacity, stiffness degradation, and energy dissipation behaviour. e test results showed that the appearance characteristics of the six column specimens exhibited varying degrees of visual damage as a result of the simulated acid rain exposure. All six specimens were dominated by similar flexural-shear failures under low cyclic reversed loads, regardless of the distinctions in the corrosion levels or stirrup ratios. For the specimens with the same ratios of stirrup, as the corrosion level increased, the load-carrying capacity, deformation capacity, stiffness, and energy dissipation capacity were continuously decreased. For the specimens with the same levels of corrosion, the higher the stirrup ratio was, the stronger the restraint effect of the stirrups on the concrete, and the seismic behaviours of the specimens were obviously improved.
Existing studies on the global expansion of banks have been mostly based on the experience of the banks from more developed economies, while little is known about the geographies of internationalization of banks from less developed countries. The expansion of Chinese banks, with state‐owned commercial banks in the lead, has been accelerating since the Belt and Road Initiative (BRI) was proposed in 2013. This study contributes to existing research by providing new evidence and explanations based on the case of expansion of Chinese banks along the BRI routes. Chinese banks started to expand from Hong Kong and Macao, then expanded to Southeast Asia and the Arabian Peninsula, and finally reached Central Asia and other regions. The branches of Chinese banks are mainly clustered in Southeast Asian countries rather than other regions. Similar to their Western counterparts, Chinese bank branches are inclined to agglomerate in international or regional financial hubs. The regression analysis shows that two factors are crucial in explaining the spatial distribution of Chinese banks along the routes of the BRI. First, Chinese banks are likely to follow their customers, namely, state‐owned firms from the non‐financial sectors making direct investments in overseas regions. Second, Chinese banks are more inclined to open branches in countries that have good geopolitical relations with China reflecting the challenging international environment for Chinese banks to seek global expansion.
