智慧专业化视角下区域资源集聚与区域创新驱动发展

传统发展动力逐渐式微，创新驱动成为区域经济发展的新引擎。走创新驱动发展道路，需要新的经济理论解释、构建并指导各区域经济增长方式和发展模式转型。智慧专业化是一种新兴经济理论，能够较好解释区域创新驱动发展的内在动力。智慧专业化有效支撑区域资源集聚与区域创新驱动发展相关性研究，从资源内存性和外向性、资源技术和经济属性以及资源支持程度3个方面，论述区域创新驱动发展的动力来源与动力持续性，进而解释区域创新驱动发展资源集聚对区域创新驱动发展绩效的影响。     

Managing security risks for inter-organisational information systems: a multiagent collaborative model

Information sharing across organisations is critical to effectively managing the security risks of inter-organisational information systems. Nevertheless, few previous studies on information systems security have focused on inter-organisational information sharing, and none have studied the sharing of inferred beliefs versus factual observations. In this article, a multiagent collaborative model (MACM) is proposed as a practical solution to assess the risk level of each allied organisation’s information system and support proactive security treatment by sharing beliefs on event probabilities as well as factual observations. In MACM, for each allied organisation’s information system, we design four types of agents: inspection agent, analysis agent, control agent, and communication agent. By sharing soft findings (beliefs) in addition to hard findings (factual observations) among the organisations, each organisation’s analysis agent is capable of dynamically predicting its security risk level using a Bayesian network. A real-world implementation illustrates how our model can be used to manage security risks in distributed information systems and that sharing soft findings leads to lower expected loss from security risks.

国际资金循环测度的统计方法及应用

研究目标：本文研究如何测量国际资金循环（Global Flow of Funds，GFF），试图整合国际金融相关数据源，创建GFF统计矩阵。研究方法：讨论了GFF的基本概念，确定了国际资金循环的统计范围。按照2008SNA所提倡的From Whom to Whom 的统计基准，建立了GFF的统计框架，据此框架整合了国际金融组织之间的数据系统关系和现有的国际金融统计数据源。研究发现：利用相关统计创建了GFF矩阵模型表，试编了一个包含中国在内的由11个国家所构成的“国家×国家”的GFF统计矩阵表。研究创新：创建了GFF矩阵表，展开了以中国为主要观测对象的国际跨境资本比较分析。研究价值：建立了观测GFF统计，开辟了新的分析视野，客观揭示了中国在GFF中的状况及现存的主要问题。

Optimal investment-consumption-insurance with random parameters

This paper discusses an optimal investment, consumption, and life insurance purchase problem for a wage earner in a complete market with Brownian information. Specifically, we assume that the parameters governing the market model and the wage earner, including the interest rate, appreciation rate, volatility, force of mortality, premium-insurance ratio, income and discount rate, are all random processes adapted to the Brownian motion filtration. Our modeling framework is very general, which allows these random parameters to be unbounded, non-Markovian functionals of the underlying Brownian motion. Suppose that the wage earner’s preference is described by a power utility. The wage earner’s problem is then to choose an optimal investment-consumption-insurance strategy so as to maximize the expected, discounted utilities from intertemporal consumption, legacy and terminal wealth over an uncertain lifetime horizon. We use a novel approach, which combines the Hamilton–Jacobi–Bellman equation and backward stochastic differential equation (BSDE) to solve this problem. In general, we give explicit expressions for the optimal investment-consumption-insurance strategy and the value function in terms of the solutions to two BSDEs. To illustrate our results, we provide closed-form solutions to the problem with stochastic income, stochastic mortality, and stochastic appreciation rate, respectively.     

The effect of human resource practices on perceived organizational support in the People’s Republic of China

Using a sample of workers and managers employed by a hotel located in Southeastern People’s Republic of China, we investigated the relationship between various human resource management practices and the perceived organizational support (POS) experienced by the employees. We then investigated the effects of POS on employee satisfaction. Our data suggest that hiring practices, training, and compensation practices predict POS. These results are consistent with previous research. We also found that POS influences worker satisfaction and acts as a mediator between select HR practices and satisfaction. This study contributes to the literature by replicating Western-based findings with a Chinese sample and illustrating that the attitudes of Chinese employees can be influenced through the use of HR practices.     

基于会计结算的第三方物流企业风险防范问题的研究
