基于径向基神经网络的非寿险公司财务预警研究

选取我国保险行业中40家非寿险公司2006~2008年的混合非平衡面板数据作为研究样本,采用径向基神经网络模型从偿付能力、盈利能力、成长能力三个角度对非寿险公司财务预警进行研究。实证表明,此模型可以为管理层的财务预警提供更有有效的信息,并且在我国保险业具有样本量小,有效数据少的情况下,有着良好的运用前景。     

中小企业网络联保贷款优势的一种理论解释

本文从降低交易成本的理论角度出发,分析了网络联保贷款的优势。认为在引入网络公司后,网络联保贷款能进一步降低信息不对称,信用约束机制能更有效地抵制机会主义行为,实质性地降低贷款的交易成本,从而促进了中小企业融资。并且就完善网络联保贷款制度提出相关的建议。     

网络时代视域下提高党建育人功能性探析

目前网络发展日益迅速,给中国社会发展带来深刻影响,也给党的育人工作提出了新的挑战。本文从网络时代提高人民思想层次的必要性和党如何利用网络开展育人工作两方面进行了分析。     

基于SMAC的无线传感网络组网方式

无线传感网络(WSN)具有十分广阔的应用前景,但以往的自组织组网方法仍有一些不足。本文首先对比分析以往的组网方法,根据无线传感网络的特点,提出了一种基于SMAC的自组织组网方法,最后与SMAC方法进行了实验对比。实验表明这种方法提高了网络资源的利用率,使网络链接的时间明显缩短,同时也减少了能耗。     

认知资本视角下项目沟通网络动态评价与调整

当前基于静态评价项目沟通网络提出的网络调整策略方式,与该网络在协同创新项目中的动态演化特点不符。认知资本是沟通的基础,且认知资本随项目推进而变化的特点与沟通网络动态性相一致,故从认知资本视角对沟通网络进行动态分析。首先,从初始网络构造、网络演化过程、演化结果评价、网络演化算法4个方面设计沟通网络演化模型。然后,以工业技术研究院协同创新项目为例,对比分析不同的网络调整策略及其效果。结果发现,劣势节点策略不仅未改善网络演化结果,反而使结果变差,表明网络局部最优不代表整体最优;优势节点策略效果较好,其中节点结构改善策略优于节点能力提高策略,表明在沟通网络演化过程中结构系统性影响强于节点个体影响。     

Diversification of cable television firms into broadband products

This research provides a new perspective to investigate the broadband diffusion in eight states of the U.S. by studying the two-stage entry decisions, namely, upgrading and subsequent product decisions, by the cable television system operators, one of the early dominant players in the broadband market, and examines the role of competition, market characteristics and firm heterogeneity in the cable company's decisions in a dynamic setting. Comparing the empirical results of the decision models of both stages can give new insights into the dynamics of broadband diffusion. The empirical results show that the subsequent product decision is affected more by the demand determinants, while the upgrading decision is affected more by the cost determinants. The results also indicate that policies which aim to reduce the entry cost such as a low city fee can largely encourage firms to upgrade the network, while subsequent policies that help boost the demand can help firms diversify into new digital services early. The effectiveness of competition policy in the broadband diffusion is confirmed in both stages. Strategic responses by cable firms to the presence of RBOCs are more noticeable in the second-staged product decision than in the first-staged upgrading decision.     

Intellectual structure of strategic management research in the hospitality management field: A co-citation analysis

This study investigates the intellectual structure of strategic management (SM) research in the hospitality industry through co-citation analysis. This study analyzes the evolution of SM research from related SM articles inclusively published in hospitality- and tourism-focused journals as well as business- and management-focused journals from 1971 to 2016. This study is the first to map the intellectual structure of SM research in the hospitality industry to analyze the changes in the influence of the most significant studies, journals, and disciplines/fields as well as the relationships among the subfields on SM research in the hospitality industry. This study suggests that marketing is a dominant subfield in SM research within the hospitality industry. In addition, the resource-based view is a dominant approach in the field, although the positioning school was dominant during the field’s early stages.     

Optimal freeware quality in the presence of network externalities: an evolutionary game theoretical approach

New software products often face difficulty in achieving market penetration. A potential remedy is to offer a freeware version of the software to encourage initial adoption and establish a larger user base for the software, thereby increasing the commercial version's value to adopters in future periods. However, to avoid complete cannibalization of the commercial version, the freeware version's quality must be sufficiently low and the price of the commercial version must not be too high. We model the effect of these two decision variables, price and freeware quality, on the adoption of software using static and evolutionary game theory.     

Assessing and planning resilience in tourism

This research note reflects the lack of work on tourism governance and resilience with regard to interrelated impacts of global environmental change. For tourism management, assessing and planning resilience is of growing importance since change processes and their interrelations have become more complex in a globalized, accelerated world, placing tourism under pressure to respond and adapt to various factors. Adaptation and transformation processes to changing environmental, social and economic conditions require initiatives by various tourism actors with different functions in the tourism supply chain, and on different scales of governance, to be able to assess, plan and manage resilience over time. Resilience as a concept has much explanatory power that requires more attention in tourism research, both from a quantitative network governance and a more qualitatively informed research perspective.
