货币危机频繁爆发的原因及对策——兼论我国金融体系改革

商业银行股份制改造已进入实质性阶段,以此为契机,中国金融体系改革也面临着前所未有的机遇与挑战。在经济、金融自由化的今天,我国将要面临的风险与外部冲击必然会增多。在此背景下重提货币危机,有着较为重大的理论与现实意义。     

The Effects of Attributes on the Repeat Sales Pattern of Residential Property in Hong Kong

There has been copious research work on the development of house price models and the construction of house price indices. However, results in some studies revealed that the accuracy of such indices could be subject to selection bias when using only information from a sample of sold properties to estimate value movements for the entire housing stock. In particular, estimated house price appreciation is usually systematically higher among properties that change hands more frequently. It therefore suggests that the determination of important factors affecting the transaction frequency or intensity of a housing unit should be a more fundamental research question. This paper examines the possible factors that determine the popularity of residential unit by means of a repeated sales pattern. The Poisson regression model and event history analysis techniques are employed to assess the effect of attributes on transaction frequency and intensity. The event history analyses technique can take account of transaction-specific as well as time-dependent covariates, and therefore is recommended for analyzing repeated sales data in a real estate market. All transaction records during the period 1993–2000 from the Land Registry of one of the most popular residential estates in Hong Kong were used to illustrate the method. Unlike a response to favorable transaction price, good quality units do not necessarily inherently display a high transaction frequency. Rather, units of average quality are more likely to be transactionally active.     

关于企业集团合并申报纳税的思考

随着“两法合并”步伐的加快,有关企业集团合并申报纳税的相关问题,税企双方均应予以重点关注,本文拟从实践角度对这一问题加以探讨。合并申报纳税的发展状况近年来随着国际竞争的加剧,呈现出以所得税政策适应企业组织结构调整的趋势,其中一个重要特征就是打破了传统会计主体与     

高管过度自信、研发投入跳跃与企业绩效——来自中国上市公司的经验证据

基于间断平衡理论和高阶梯队理论，以2007-2017年中国沪深两市902家制造企业为样本，实证分析研发投入跳跃对企业绩效的影响以及高管过度自信的调节作用。结果显示：研发投入正向跳跃和负向跳跃均有助于提升企业绩效，高管过度自信正向调节研发投入跳跃与企业绩效间的关系。引入高管过度自信这一重要高管特征作为调节变量，有助于重新认识管理者心理偏差对企业创新行为和绩效的影响，较好地弥补了研发投入跳跃对企业绩效影响机制的研究空缺，丰富了创新间断平衡理论研究。研究表明，企业应重视高管心理特征的影响并结合自身实际情况，合理选择研发投入策略以改善企业绩效。     

REAL OPTIONS WITH COMPETITION AND REGIME SWITCHING

In this paper, we examine irreversible investment decisions in duopoly games with a variable economic climate. Integrating timing flexibility, competition, and changes in the economic environment in the form of a cash flow process with regime switching, the problem is formulated as a stopping‐time game under Stackelberg leader‐follower competition, in which both players determine their respective optimal market entry time. By extending the variational inequality approach, we solve for the free boundaries and obtain optimal investment strategies for each player. Despite the lack of regularity in the leader's obstacle and the cash flow regime uncertainty, the regime‐dependent optimal policies for both the leader and the follower are obtained. In addition, we perform comprehensive numerical experiments to demonstrate the properties of solutions and to gain insights into the implications of regime switching.     

围绕产业链部署创新链——论科技创新与产业创新的深度融合

当代国际竞争突出表现为全球价值链竞争。创新发展的关键是推动产业迈上全球价值链中高端。突破口就是围绕产业链部署创新链，把科技创新落到产业发展上。我国产业迈上全球价值链中高端主要有两个方向：一是建立以我国拥有的核心高端技术为主导的全球价值链，二是从全球价值链中低端环节向中高端环节攀升。这两个方向实际上指明了围绕产业链部署创新链的方向。在产业链上部署创新链，关键是在相应的产业链环节上创新处于国际前沿的核心技术。产业创新链的基本功能是有效衔接知识创新和技术创新两大体系。产学研协同创新更适合产业创新链的构建。

Policy Dimensions of Progressive Institutional Change: Lessons from China’s Construction of a Socialist Market Economy

Abstract:

Through a comprehensive review of the progressive institutional change (PIC) literature, I first discuss four possible trajectories of PIC by considering the forces of societal reaction that might frame the path, as well as the scale and scope of the changes. Thus, I pose four questions that need to be asked when related policies are formulated for PIC. To illustrate this method, I scrutinize the evidence from the construction of a socialist market economy by the Chinese government since the 1980s and argue that related policies have successfully promoted PIC from three dimensions: (1) curbing potential conflicts with power groups; (2) promoting a sense of awareness among stakeholders; and (3) minimizing disturbances to the community. Actually, the related changes demonstrate a dynamic “displacement process” for PICs. Despite the success of this sociosystem, it is found that the sustaining of PIC which requires policy factors that enhance instrumental efficiency in the Chinese context will serve as a challenge to the Chinese government ahead.     

中国“一带一路”战略定位的三个问题

"一带一路"战略在大方向基本清晰的情况下,在战略定位上仍然存在着三个有待进一步厘清的问题,包括:"一带一路"是全球战略还是区域战略?"一带一路"应以多重双边伙伴关系为基础还是应以跨区域整合为基础?"一带一路"战略应以西北方向为优先还是应以东南方向为优先?对这三个问题的诠释对于"一带一路"战略的推进有着极为重要的意义。这一战略虽然表现出了一定的全球战略的特征,但在本质上还是区域性的;其的推进必须以多重双边伙伴关系为基础。就目前的具体政治形势与经济形势来看,"一带一路"战略开拓西北面临更大的不确定性。     

基于粒子群算法下的交叉口信号配时优化

为了合理地优化交叉口信号配时,通过分析交叉口的评价指标,建立了以车辆的平均延误、停车次数最小、交叉口整体通行能力最大、各相位有效绿灯时间和交叉口周期时长作为约束条件的数学模型。并通过改进前人研究基础上的动态加权系数,将多目标的非线性优化问题转化为单一目标的非线性规划问题,为了得出更科学稳定的解,提出了改善粒子群算法系统稳定性的2种方法,并将其与粒子群算法结合起来。然后以Matlab为求解工具,结合临邑市某一交叉口实例进行求解分析。最后的结果表明,在使用改进后的粒子群算法进行优化后交叉口通行能力较之现状提升了9%,延误下降了28%,停车次数下降了9%,且各项优化结果均优于Webster,改进后的算法在程序中运行300代,到216代才开始收敛,而未改进的算法稳定性较差,优化结果和收敛曲线则随着实验次数的变化而变化,最后的结论证明了该算法和模型的可靠性。
