In terms of delineating sphere of urban influence, existing studies have been focused on static study by using single year data or single method, resulting in a lack of time-series longitudinal analysis or comprehensive analysis based on multiple methods This study emphasizes on comparing two methods from both the theoretical and empirical perspective. Both gravity model and improwd field model are applied to the selected study area for measurements and comparison, to explore their strengths and weaknesses. A research framework for comprehensive analysis on delineating sphere of urban influence is proposed. In the end, the differences of deli：aeating methods are illustrated and the feasibility of comprehensive analysis is discussed. Recommendations are provided for selecting appropriate methods for delineating sphere of urban influence or developing regional hierarchy system plans and urban spatial structure schemes.展开更多

The aim is to summarise the policy tendencies of the international organisations （NATO and EU） towards Russia and to present some analytical thoughts on current Euro-Atlantic strategies. Proposed is a different way of thinking based on the ＂congagement＂ approach.展开更多

In South Asia, most of the countries embraced the idea except India. There is no doubt that OBOR is likely to have farreaching implications on South Asian politics, economy and security. China has been engaging in the region through various economic and development projects for last two decades. This has raised serious security and strategic concerns in India. China＇s growing bilateral trade investments and development-oriented connectivity projects in India＇s neighbourhood have been popularly dubbed as China＇s ＇String of Pearl Strategy＇ aimed to contract India＇s sphere of influence in the region. There is a deficit of trust between emerging India and rising China over their interests and intentions. Many observers, however, view OBOR as a game changer at least in South Asia, where this would necessitate re-alignment and re-balancing. But, how does India perceive this project is a matter of serious concern that would shape the nature of implications on South Asia？ In this context, this article examines the impact of OBOR on South Asia Region from sub-regional perspectives and it explores how China can play a constructive role by reconciling its grand strategy with national interests of South Asian countries in order to minimise the adverse impact of OBOR [especially China-Pakistan Economic Corridor （CPEC）] on the peace and security of the region through effective CBMs.展开更多
