连续进化金融模型与全局渐进化稳定策略   总被引:2,自引:0,他引:2  
本文运用达尔文生物进化论思想研究连续交易金融市场选择的动态变化及一般均衡规律。本文发现并证明了:金融资产“赢利”的充要条件是该资产相对股息大于相对股价;投资比例等于股息分发比例的简单混合策略是全局渐近进化稳定策略;在均衡条件下,对应的金融资产价格等于该资产股息占总股息的比例的数学期望;市场变异或金融创新是有效市场形成的动力;全局渐近进化稳定策略业绩可能在某些时候不是最好的,但只要其初始财富大于零,最终将控制市场上的所有财富,而简单混合策略,可能在某个时候业绩优良,然而,在市场存在全局渐近进化稳定策略的条件下,只要其初始财富份额小于1,最终控制的财富趋向于零,从而被市场所淘汰。  相似文献

中央银行再贷款:泛化、反稳定性与道德风险   总被引:1,自引:1,他引:1  
中央银行再贷款是中国人民银行投放基础货币的重要渠道,是我国特有的一种货币政策工具。基于对新形势下中央银行再贷款制度变迁的分析,现行再贷款政策存在泛化、准财政化、反稳定性、衍生道德风险等问题,必须从制度上规范再贷款的运用,并适时建立金融稳定机制。  相似文献

New product development (NPD) has long been recognised as one of the corporate core functions. However, measuring new product success has remained elusive. This paper attempts to examine several conceptual issues underlining the measurement of new product success and the measurement practice adopted in Australian small and medium enterprises (SMEs). The sample included 276 SMEs from two most innovative industries: chemical and machinery industries. Results have indicated that four factors underline the commonly used success measurement: financial performance, objective market acceptance, subjective market acceptance, and product-level measures. These four factors are related to each other and can be used to well predict the overall measurement. The most frequently used specific measures in Australian SMEs are customer acceptance, customer satisfaction, product performance, and quality.  相似文献

The adoption of sophisticated supply chain innovations by trading partners in global channels of distribution is often limited by the institutional context of the international transaction. In particular, the regulatory, normative, and cultural-cognitive elements of institutional environments around the world can enhance or inhibit the ability of trading partners to craft the contractual, ownership, and social elements of institutional arrangements required by an innovation. Because supply chain innovations often require costly, new investments and activity sets, firms may be reluctant to participate in an innovation unless a new institutional arrangement can be crafted to provide adequate safeguards and guarantees. A conceptual model is developed to explain the role of institutions in the successful deployment of supply chain innovations in global marketing channels.  相似文献

中国政府对高新技术企业投入了大量补贴以激励它们创新,但是对补贴效果的研究并未达成一致结论。基于中关村3万多个高新技术企业2001-2012年的观察值,本文同时采用PSM与DID法对政府补贴的效果进行了研究,结果发现:第一,整体而言,政府补贴显著提高了创新经费支出、新产品销售收入和专利申请数量;第二,进一步将创新细分为自主创新和购买引进新技术之后发现,政府补贴存在“挤出效应”:被补贴企业的自主创新明显下降,而购买引进新技术显著增加;第三,政府补贴对企业的短期创新激励有显著的促进作用,但是对长期创新激励的促进作用不显著。本文对高新技术企业的补贴效果提供了实证绩效评估,所得出的结论有助于政府优化和调整激励创新政策。  相似文献

ABSTRACT

This study, utilizes an innovative methodological approach, fuzzy-set Qualitative Comparative Analysis (fsQCA), investigating the drivers of heterogeneous geographies characterizing English Local Economic Partnerships (LEPs). The fsQCA technique offers a novel configurational alternative to regression-based approaches investigating the effects of clustering in conjunction with firm-level innovation, university third-sector activity (TSA) and entrepreneurship, on LEPs innovation performance. The findings, offer contributions to the theories of industrial clusters and innovation, regional innovation systems, knowledge spillovers and entrepreneurial university innovation within LEPs. First, supporting fsQCAs, no individual variable generates either a positive/negative innovation outcome. Second, while all positive innovation recipes include presence of the cluster variable, for negative innovation recipes, only one does not identify absence of clustering as relevant. Given that the cluster variable does not appear in any recipes without at least one of the other variables suggests activity concentration does not exist in isolation to generate innovation outcomes without other localized conditions existing, e.g. firm-level innovation. Third, there is evidence for the non-cluster-based aspects of knowledge spillover theory of entrepreneurship with respect to university activity and the entrepreneurial university concept. Instead, roles of entrepreneurship and university TSA, while important, appear to be more peripheral and geographically context specific.  相似文献

We investigate how access to different types of resources affects the success of entrepreneurial start-up firms at early stages of development in small isolated economies by studying 12 start-ups based in New Zealand. We find that successful commercialization of innovations depends on the availability of complementary assets, and that capability-based resources, especially dynamic capabilities, have a greater impact on competitive advantage of start-ups than other intangible and tangible assets. For the start-ups in our study, alliances with partners are particularly important, and so the ability to form alliances is a key capability. Successful start-ups leverage their available resources to attract alliance partners in order to access necessary complementary resources. The start-ups in our study clearly demonstrated the ability to attract partners locally but struggled to do so internationally, thereby limiting their growth potential.  相似文献

The current study examines the effect of disinvestment (dilution of state ownership) and local political corruption on R&D spending in enterprises owned by the central government of India. Based on certain characteristic features of innovation as a strategy available to state-owned enterprises, I build two sets of hypotheses formalising the channels of how these variables may affect the possibility and amount of R&D. Data is drawn from multiple sources to compile a dataset that covers all manufacturing central government-owned enterprises in India over a period of ten years from 2007 to 2016. The study employs an instrumental variable technique to reduce the endogeneity between disinvestment and R&D decisions. We find that, while disinvestment and local political corruption have strong negative effects on whether a firm invests in R&D or not, it has no effect on the amount of R&D. In fact, the amount is driven by a host of firm-specific factors such as size, profit and proficiency of the share of skilled labor, managerial strength and non-unionisation of labor. We also find that the effects are strongly driven by the size of firms, special status awarded to firms and the ideology of the state where the enterprise operates.  相似文献

知识治理是知识管理理论发展的新阶段,在动态复杂的创新环境下,知识治理与创新的关系已成为学术界关注的热点话题。对高新技术企业进行问卷调查,探讨知识治理对协同创新绩效的影响并采用有调节的中介效应模型,分析知识转移和制度环境在其中的作用机制。结果表明,正式知识治理与非正式知识治理均会对知识转移产生正向影响;知识转移在知识治理与协同创新绩效关系中存在完全中介效应,即知识治理对协同创新绩效的正向效应是通过知识转移实现的;制度环境正向调节知识转移对协同创新绩效的影响,即在良好的制度环境下,知识转移的中介作用更强。  相似文献
