Does Foreign Bank Entry Make Chinese Banks Stronger?
Yingkai Yin,Yahua Zhang,Xiaotian Tina Zhang,Fang Hu 연세대학교 동서문제연구원 2015 Global economic review Vol.44 No.3
China has encouraged its domestic banks to introduce foreign investment since the early 2000s. In the meantime, China has gradually fulfilled its World Trade Organisation (WTO) accession commitment to give foreign banks the same treatment as their Chinese counterparts in the last decade. This research has examined the effects of the two modes of foreign bank entry, namely, minority ownership participation, and setting up branches and subsidiaries, on the performance of Chinese banks. Our results suggest that there is no systematically significant impact of the minority ownership participation on the performance indicators of Chinese banks. However, it appears that the physical presence of foreign banks has been a significant driver for domestic banks to improve profitability and efficiency. Opening the country to foreign banks appears to have made Chinese banks stronger and more competitive.

Performance Analysis and Evaluation of Deployment in Small Cell Networks
( Kan Zheng ),( Yue Li ),( Yingkai Zhang ),( Zheng Jiang ),( Hang Long ) 한국인터넷정보학회 2015 KSII Transactions on Internet and Information Syst Vol.9 No.3
Small cells are deployed in Heterogeneous Networks (HetNet) to improve overall performance. These access points can provide high-rate mobile services at hotspots to users. In a Small Cell Network (SCN), the good deployment of small cells can guarantee the performance of users on the basis of average and cell edge spectrum efficiency. In this paper, the performance of small cell deployment is analyzed by using system-level simulations. The positions of small cells can be adjusted according to the deployment radius and angle. Moreover, different Inter-Cell Interference Coordination (ICIC) techniques are also studied, which can be implemented either in time domain or in frequency domain. The network performances are evaluated under different ICIC techniques when the locations of Small evolved Nodes (SeNBs) vary. Simulation results show that the average throughput and cell edge throughput can be greatly improved when small cells are properly deployed with the certain deployment radius and angle. Meanwhile, how to optimally configure the parameters to achieve the potential of the deployment is discussed when applying different ICIC techniques.
