浅议我国资产评估管理体制的重构

20世纪80年代末,随着国有企业的重组改制、产权交易和中外合资、合作等经济活动的不断增多,资产评估作为为产权交易、合资合作等经济活动提供价值咨询服务的社会中介行业便应运而生.十多年来,资产评估积极参与改革,服务改革,已成为我国经济建设中不可或缺的公证性社会中介服务行业.随着我国加入WTO,我国资产评估行业既面临着前所未有的发展机遇,同时也承受着巨大的挑战,在评估理论上有很多问题需要深入研究,在评估实践操作上还亟待总结规范,尤其是评估管理体制更是存在着许多错综复杂的问题需要解决.     

Political hazards and entry modes of Chinese investments in Africa

Africa has achieved the fastest growth rate of inward foreign direct investment (FDI) recently. Yet heightened political hazards present substantial challenges to foreign firms in Africa. This study examines the entry strategies that firms may take to mitigate such hazards by exploring the relationship between political hazards and entry mode choices in Africa. We further consider how an investing firm’s host country experience and foreign aid provided by its home country government to host countries in Africa can influence this relationship. In a sample of listed Chinese firms’ investments in Africa from 2000 to 2014, we find that Chinese firms tend to use the joint venture mode when political hazards are high in an African country. This relationship is weakened when they accumulate host country experience and when the Chinese government’s foreign aid to an African country increases. Our findings point to firm-level strategies to mitigate political hazards as well as instruments available to home country governments to help their multinational firms operating in host countries characterized by unstable political environments.

城市基础设施经营机制的改革--市场化

我国城市基础市政公用设施供给不足,另一方面建设资金严重匮乏,投资结构不尽合理,制约了它的发展.城市基础设施经营机制的改革--市场化势在必行.市场化意味着城市基础设施产品和服务可以由政府以外的经济主体来投资建设和经营,并向公众提供.但是政府要对其进入条件、价格合理性、产品的技术质量等进行适当的干预.

水杨酸和茉莉酸甲酯对喜树种子中次生代谢产物含量的影响

水杨酸和茉莉酸甲酯均使萌发喜树种子喜树碱含量在初期下降,后期上升;但其衍生物10-羟基喜树碱在第1天迅速上升,但随后几天水杨酸处理组一直低于对照,茉莉酸甲酯处理组相对对照呈波动变化,且高浓度茉莉酸甲酯处理下波动幅度更大。种子中总酚和总黄酮含量均呈逐渐下降趋势,但不同处理未发现明显差异。     

Limit theorems for reflected Ornstein–Uhlenbeck processes

This paper studies one‐dimensional Ornstein–Uhlenbeck (OU) processes, with the distinguishing feature that they are reflected on a single boundary (put at level 0) or two boundaries (put at levels 0 and d > 0). In the literature, they are referred to as reflected OU (ROU) and doubly reflected OU (DROU), respectively. For both cases, we explicitly determine the decay rates of the (transient) probability to reach a given extreme level. The methodology relies on sample‐path large deviations, so that we also identify the associated most likely paths. For DROU, we also consider the ‘idleness process’ L_t and the ‘loss process’ U_t, which are the minimal non‐decreasing processes, which make the OU process remain ≥ 0 and ≤ d, respectively. We derive central limit theorems (CLTs) for U_t and L_t, using techniques from stochastic integration and the martingale CLT.
