企业物流服务组织模式与决策动因的对应分析

企业物流服务组织中的主要模式一般包括物流外包、物流自营以及部分外包部分自营。在现实中,由于受到复杂主、客观环境因素的影响,企业在进行物流服务模式的选择时必须考虑诸多因素,以形成合理的、具有针对性的决策方案。因此,研究企业物流服务组织模式与决策动因之间的关系非常重要。本文通过对物流服务需求方实体企业的抽样调查分析,从企业所在系统和环境因素入手来挖掘企业决定其物流组织模式的主要动因,运用对应分析方法对不同物流服务模式与决策动因之间的关系进行研究,从而为企业的物流决策行为提供借鉴。     

中国对外直接投资的发展趋势与政策展望

中国已是世界上对外直接投资最大的发展中国家,也是全球第五大对外直接投资大国。中国对外直接投资与发达国家和发展中国家过去的投资模式不同,而是遵循一种价值链延伸型的发展趋势。中国的对外投资政策,已经朝着符合中国对外直接投资发展趋势的方向改变,但是,不管是战略层面,还是核准与管理制度层面,以及促进政策方面,要有效地支持中国当前和未来相当长一段时期内的价值链延伸型为主的对外直接投资,还需做出一些调整。

居民收入差距与财政政策的关联度

改革开放以来,我国城乡经济获得较大的发展,城乡居民的收入水平有了很大的提高,城乡关系也得到了逐步改善,但城乡居民收入差距过大问题依然存在。财政是政府发挥作用的重要方式和手段,有其不可替代的功能,在缩小城乡居民收入差距、促进农民增收过程中担负着重要使命。建议加大财政对农业的总量投入,优化财政支农资金结构,加大财政对农村公共品供给的投入,完善现行财政管理体制。     

Behavior patterns of investment strategies under Roy’s safety-first principle

The safety-first principle is a natural motivational factor in decision making, and is closely related to certain popular heuristics such as satisficing. We provide a systematic analysis of optimal portfolio choice under Roy’s safety-first principle by examining and comparing the behavior patterns of three popular investment strategies: the optimal constant-rebalanced portfolio, dynamic-rebalanced portfolio and buy-and-hold strategies. Our results indicate the importance of a match between the investment strategy, the investment goal, and the investment horizon. We also develop a geometric approach to investigate the relationships among the safety-first, expected utility, and mean-variance models and offer an explanation for the long-standing debate concerning different patterns of time-diversification effects.     

融入策划思想的规划思路探讨——以同里景区控制性规划为例

经济全球化的大背景下,投资体制、资源和利益分配体制都快速的摆脱原来计划经济的轨道,越来越受市场规律的引导和制约,在投资渠道越来越多元的今天,建设程序也有了很大的不同,这些变革都要求我们在规划过程中打破原来以物质空问规划为重心的规划方式,全方位的革新规划的技术方法和思路.为了在规划过程中真正理解规划实施的最重要因素"市场需求",我们尝试在同里景区控制性规划中借鉴市场营销等方面的理论,引入市场策划的思想,力求让规划成果兼顾投资方利益以及公共利益,使之在实施过程中具有更高的可行性和可操作性.

Computing DSGE models with recursive preferences and stochastic volatility

This paper compares different solution methods for computing the equilibrium of dynamic stochastic general equilibrium (DSGE) models with recursive preferences such as those in Epstein and Zin, 1989, Epstein and Zin, 1991 and stochastic volatility. Models with these two features have recently become popular, but we know little about the best ways to implement them numerically. To fill this gap, we solve the stochastic neoclassical growth model with recursive preferences and stochastic volatility using four different approaches: second- and third-order perturbation, Chebyshev polynomials, and value function iteration. We document the performance of the methods in terms of computing time, implementation complexity, and accuracy. Our main finding is that perturbations are competitive in terms of accuracy with Chebyshev polynomials and value function iteration while being several orders of magnitude faster to run. Therefore, we conclude that perturbation methods are an attractive approach for computing this class of problems.     

Bank ownership,privatization, and performance: Evidence from a transition country

This paper combines the static effect of ownership and the dynamic effect of privatization on bank performance in China over 1995–2010, reporting a significantly higher performance by private intermediaries – joint stock commercial banks and city commercial banks – relative to state-owned commercial banks. However, publicly traded banks, subject to multiple monitoring and vetting in capital markets, perform better regardless of ownership status. The privatization of banks has improved performance with respect to revenue inflow and efficiency gains in the short- or long-run (initial public offerings). The positive long-run effect is more relevant and significant for banking institutions with minority foreign ownership. Moreover, this paper innovatively estimates interest income efficiency and non-interest income efficiency at the same time. The results suggest that Chinese banks are much more efficient in generating interest income than raising non-interest revenue, although the latter aspect has improved significantly during the sample period.
