Explanations for the weak information acquisition ability of new generation migrant workers 新生代农民工信息获取能力弱的原因解释
Yao Yuan, Zhang Guang-sheng, Liu Wei
Job information is the basic resource for employment, job information acquisition ability directly affects the employment of new generation migrant workers. This paper analyzed job information acquisition ability through normal channels of new generation migrant workers from different types of the cities from both supply and demand aspects, used Demand-Identified Bivariate Probit Model to analyze factors that effect their information acquisition ability through the normal channels. The results show that: 1 the weak ability of information acquisition of new generation migrant workers not only relates to the information supply but also the demand of it; 2 frequent change of cities and jobs make their job information demand decrease; the ones with low technical level have strong information demand, while the supply is poor. Therefore, reducing their changes of cities during mobility, improving their occupational technology level and developing and satisfying their job information demand from normal channel is the fundamental way to improve their information acquisition ability and guarantee their employment.
岗位信息是就业的基本资源,岗位信息获取能力直接影响到新生代农民工的就业。本文从供给和需求两个方面分析了不同类型城市新生代农民工通过正常渠道获取工作信息的能力,运用需求识别双变量Probit模型分析了影响新生代农民工通过正常渠道获取工作信息能力的因素。研究结果表明:1新生代农民工信息获取能力弱,既关系到信息供给,也关系到信息需求;2 .城市和工作的频繁变化使其对工作信息的需求减少;技术水平低的企业信息需求旺盛,信息供给不足。因此,减少他们在流动过程中对城市的变化,提高他们的职业技术水平,从正常渠道开发和满足他们的职业信息需求,是提高他们信息获取能力,保障他们就业的根本途径。

Anew assumption in generation mechanism of emergency plan under the perspective of “scenario-task” “情景-任务”视角下应急预案生成机制的新假设
Yang Yi, Li Lin
This article puts forward an idea of generating emergency plan under the “scenario-task” perspective and clarifies the main content and key technology roadmap of the research starting from problems existing in the domestic emergency plan. Based on the summary of typical emergencies evolution, by means of making the research on the classification and grading of emergency scenarios and the constitution of scenario elements, the network analytical model of emergency scenario evolution is hierarchically formed. This model is made up of incentive layer, rule layer and events chain layer. At the same time, with national strategic task, regional coordination tasks and basic respond set up in the vertical direction, prevention, monitoring, response and recovery in the horizontal direction, we establish an emergency task structural matrix facing up to different kinds of scenario. It is discussed about the matching relationship between different levels of tasks and dynamic effect on the scenario evolution by the task performance. Then we seek the interaction mechanism between scenario evolution and task changes by analyzing the variable transformation between scenario, scenario element and task. The basic logic of emergency plan generation is revealed and the critical path of its dynamically generation is proposed from the aspects of emergency plan structural system, scenario and case database, task responsibility of emergency organization, emergency practice and plan evaluation.
本文提出了“场景-任务”视角下的应急预案生成思路,并从国内应急预案存在的问题出发,明确了研究的主要内容和关键技术路线图。在总结典型突发事件演变的基础上,通过对突发事件情景分类分级和情景要素构成的研究,分层次形成突发事件情景演变的网络分析模型。该模型由激励层、规则层和事件链层组成。同时,纵向设置国家战略任务、区域协调任务和基本响应任务,横向设置预防、监测、响应和恢复任务,建立面向不同情景的应急任务结构矩阵。讨论了不同层次任务之间的匹配关系以及任务绩效对场景演化的动态影响。然后通过分析情境、情境要素和任务之间的变量转换,寻求情境演化与任务变化之间的交互作用机制。从应急预案结构体系、情景与案例库、应急组织任务责任、应急实践和预案评估等方面揭示了应急预案生成的基本逻辑,提出了应急预案动态生成的关键路径。

A study to develop the instructions for setting discount rate in PFI model suitability assessment in Taiwan 台湾地区PFI模式适宜性评估贴现率设定指引之研究
Chou Hui-yu
Since 1994, Taiwanese private sector participation in public works projects have been conducted with build-operate-transfer (BOT) models that must be self-liquidating. To expand the scope of private funding for public works and service investment plans, the Taiwanese government proposed the introduction of private finance initiative (PFI) models in 2012. Consequently, Taiwan will encounter issues concerning the selection of traditional government self-financed, BOT, and PFI models for future public works investments. In response to the future introduction of policies related to PFI models in Taiwan, this study developed setting standards for discount rates, a key parameter required for assessing the suitability of PFI models. The theoretical framework is based on the Capital Asset Pricing Model. The parameter data used in trial calculations were collected from the historical case data recorded in the Public Construction Bid Management Information System of the Public Construction Commission, Executive Yuan, and employed in further analyses and imputations. The results indicate that of the six primary categories of public works examined in this study, railway works exhibit the highest risk, with an estimated systemic risk coefficient β of 0.9 and a recommended discount rate of 8.9%. Conversely, mass rapid transit system works exhibit the lowest risk, with an estimated systemic risk coefficient β of 0.3 and a recommended discount rate of 5.3%.
自1994年以来,台湾私营部门参与公共工程项目一直采用建设-运营-转让(BOT)模式,必须自行清算。为了扩大公共工程和服务投资计划的私人资金范围,台湾政府于2012年提出引入私人融资倡议(PFI)模式。因此,在未来的公共工程投资中,台湾将会遇到选择传统的政府自筹资金、BOT和PFI模式的问题。为因应未来台湾将推出与PFI模式相关的政策,本研究制定了贴现率的设定标准,贴现率是评估PFI模式适宜性所需的关键参数。理论框架以资本资产定价模型为基础。试算所使用的参数资料,采自行政院工建委员会“工建招标管理资讯系统”之历史案例资料,并用于进一步分析与推算。结果表明,在本研究考察的六个主要公共工程类别中,铁路工程表现出最高的风险,估计系统风险系数β为0.9,建议贴现率为8.9%。相反,快速轨道交通系统的工程表现出最低的风险,估计系统风险系数β为0.3,建议贴现率为5.3%。

Strategic transformation of Shanzhai firms: Evidence from the Chinese case 山寨企业的战略转型:来自中国案例的证据
Xuefeng Liu, Yanhui Wu
Last several years have seen the great growth of the Shanzhai mobile phone firms, and it is more surprising that these firms achieve such performance under the background of the global financial crisis. However, in order to acquire long term competitive advantages, Shanzhai mobile phone firms must make strategic transformation. This research tries to explain the emergence and growth of Shanzhai mobile phone firms from theoretical views of modularity and disruptive innovation. The research results suggest that technological modularity facilitates the evolution of industrial value chain, which greatly lower the threshold for local small firms' entry and promotes disruptive innovations. Shanzhai mobile phone firms start from low-end disruption and by accumulating technology and market knowledge through resource integration, some of these firms can work their way up to eventually achieve independent innovation and their own brands, becoming major players in the market. Based on the Tianyu case study, this paper explores the theoretical model about how Shanzhai mobile phone firms carry out strategic transformation, and then discusses relevant policy implications.
在过去的几年里,山寨手机公司取得了巨大的增长,更令人惊讶的是,这些公司在全球金融危机的背景下取得了这样的成绩。然而,为了获得长期的竞争优势,山寨手机企业必须进行战略转型。本研究试图从模块化和破坏性创新的理论视角来解释山寨手机企业的产生和成长。研究结果表明,技术模块化促进了产业价值链的演化,大大降低了本地小企业的进入门槛,促进了颠覆性创新。山寨手机企业从低端颠覆起家,通过资源整合积累技术和市场知识,其中一些企业最终可以实现自主创新,拥有自己的品牌,成为市场的主要参与者。本文以天宇案例为基础,探讨了山寨手机企业如何进行战略转型的理论模型,并探讨了相关的政策启示。

OPF: A novel framework for fuzzy portfolio selection OPF:一种新的模糊投资组合选择框架
Sri Cheng, C. Wei
In this paper, we propose a novel framework - the Observer Pattern Framework (OPF) - which could better reflect the complex securities market. The core of the OPF is observer collecting relevant information from two different perspectives, namely, stock price statistics and force comparison between buyer and seller. Further, based on a practical example, we not only define observer equations and their characteristic relation, but also present numerical equations of theoretical model. Finally, the application of the OPF to the fuzzy portfolio selection problem is discussed.
在本文中,我们提出了一个新的框架——观察者模式框架(OPF),它能更好地反映复杂的证券市场。OPF的核心是观察者从两个不同的角度收集相关信息,即股票价格统计和买卖双方的力量比较。在此基础上,结合实例,定义了观测器方程及其特征关系,并给出了理论模型的数值方程。最后,讨论了OPF算法在模糊投资组合问题中的应用。

Top management team managerial discretion, strategic flexibility, and firm growth performance: Evidence from China's listed small and medium-sized enterprises 高层管理团队管理自由裁量权、战略灵活性与企业成长绩效:来自中国上市中小企业的证据
Li Yuan, Wang Xue-lian, Liu Bing
Under settings of China's economic transition period, strategic flexibility is the crucial capability to allow the Chinese small and medium-sized enterprises (SMEs) to proact or respond timely and effectively to quickly changing conditions. Starting from the perspective of top management team (TMT) and its members' leadership sources, this paper explored the impact of TMT managerial discretion on strategic flexibility of SMEs, based on the resource based view. Using the sample of 165 China's listed SMEs, the empirical research identified TMT managerial discretion derived from task environment and TMT managerial discretion derived from organization as key influential factors of strategic flexibility of SMEs. However, the impact of TMT managerial discretion derived from team power-base on strategic flexibility of SMEs was not significant. The empirical results also revealed that strategic flexibility has positive effect on firm growth performance of SMEs.
在中国经济转型期的背景下,战略灵活性是中国中小企业能够及时有效地应对快速变化的环境的关键能力。本文从高管团队及其成员的领导来源视角出发,基于资源基础的观点,探讨了高管团队管理自由裁量权对中小企业战略灵活性的影响。以165家中国上市中小企业为样本,实证研究发现,任务环境的TMT管理自由裁量权和组织的TMT管理自由裁量权是影响中小企业战略灵活性的关键因素。而基于团队权力基础的TMT管理自由裁量权对中小企业战略灵活性的影响不显著。实证结果还显示,战略灵活性对中小企业成长绩效有正向影响。

Study on coordinating mode of intergovernmental relations in water resources management of river basins: Based on water resources integrated management in river basin 流域水资源管理中政府间关系协调模式研究——基于流域水资源综合管理
Z. Qiang
Shortage of water resources and aggravation of water environment have become important factors of restricting Chinese economic and social development. Faced with severe water crisis, it is the certain selection that realizes an integrated management of overall river basin to abide by natural law of water resources circle. Due to lag of the political system reform and imperfection of related systems, interrelation among multitudinous river basin management organizations is complexity and chaos; contradictions- among central and local governments, among different local governments- have seriously hindered improvement of water resources management efficiency and effective protection of water environment. To solve these problems, we can construct intergovernmental contradictions' coordination mode with restruction of river basin management organizations' function at the core, so as to reduce contradictions among multitudinous river basin management organizations, increase management efficiency of water resources, and achieve effective protection and sustainable development of water environment.
水资源短缺和水环境恶化已成为制约中国经济社会发展的重要因素。面对严峻的水危机,遵循水资源循环的自然规律,是实现整体流域一体化管理的必然选择。由于政治体制改革的滞后和相关制度的不完善,众多流域管理组织之间的相互关系复杂而混乱;中央与地方、地方与地方之间的矛盾严重阻碍了水资源管理效率的提高和水环境的有效保护。为解决这些问题,可以构建以流域管理组织职能重构为核心的政府间矛盾协调模式,减少众多流域管理组织之间的矛盾,提高水资源管理效率,实现水环境的有效保护和可持续发展。
