越南自革新开放以来。积极主动融入国际经济,注重吸引外国的直接投资,外国的资本也为越南的发展注入了新的活力,加速越南工业化和现代化国家的进程。中国和日本一直都是越南主要的投资来源国,两国对越南的投资也有明显的成效,同时存在着时代的特点。本文试图通过两国在1991年以来对越南投资的比较,全面分析两国对越南投资的现状,呈现更多两国对越南投资的新特点,并且通过比较发掘两国在对越南投资中的优劣,寻求存在异同和优劣的原因,针对两国的投资特点进一步完善越南引入外资的政策,达到充分利用外资并且优化外资投资结构的目的。在研究内容方面,本文对中国和日本在越南的投资主要从投资规模及区域、投资偏好及影响、投资趋势及态度等全方位进行,在梳理1991年以来两国对越南投资的各方面数据和资料中比较异同。比较分析中日两国对越南投资得出的结论是:一是中国对越南的投资规模还有较大的发展空间;二是日本投资结构较中国更不够合理,对第二产业的投资占比较大,缺乏投资质量;三是中日两国对投资选择有着不同的偏向,主要受地方政策、地理条件和投资偏好的影响;四是在越南对中国和日本投资态度以及两国发展趋势的比较中可进一步规划投资战略。总之,越南应根据投资现状与发展趋势对中日的投资寻求更为健康、合理的投资策略,有效利用中日对越的外资投资,促进越南经济特别的对外经济的良性发展。

Imperfect Channel State Information of AF and DF Energy Harvesting Cooperative Networks

China Communications 2016年第10期13卷 11-19页

Wireless information and powered transfer networks(WIPT) has recently been implemented in 5th generation wireless networks. In this paper, we consider half-duplex relaying system in which the energy constrained relay node collects energy via radio frequency(RF) signals from the surrounding resources. Regarding energy harvesting protocol, we propose power time switching-based relaying(PTSR) architecture for both amplify-and-forward(AF) and decode-and-forward(DF). Especially, we reveal the analytical expressions of achievable throughput, ergodic capacity and energy-efficient in case of imperfect channel state information(CSI) for both AF and DF network. Through numerical analysis, we analyse the throughput performance, energy-efficient and ergodic capacity for different parameters, including power splitting ratio and energy harvesting time. Moreover, we also depict the performance comparison between AF and DF network with perfect and imperfect CSI. The results in numerical analysis reveal that the result of AF relaying network is less significant than DF relaying network in the various scenarios.
