高校创业教育是一种新的教育理念与模式,目前还处在不断发展阶段,还没有形成一个独立的学科体系和完备的教学模式。高校要设立专门的创业组织机构。创业教育对课程教学的开放性和灵活性、整体性和系统性、实践性要求更高。因此,要以创业所需基本知识为基础,以培养创业精神为核心,以锻炼创业能力为关键,不断完善“平台+模块”的课程体系建设,突出“活动+实训”实践课程环节,建立健全科学的创业教育课程评价体系。 相似文献

Previous research shows that knowledge integration mechanisms (KIMs) mediate the cross‐functional collaboration‐product innovation performance relationship; however, this mediating effect seems to be rather weak. This study, in contrast, develops a moderated mediation (MOME) model to argue that such a mediating effect is moderated by product innovativeness. A sample comprised of 106 manufacturing firms is utilized in the analyses. A moderated‐mediation approach shows that the mediating effect of KIMs in the linkage between cross‐functional collaboration and product innovation performance varies by different perspectives of product innovativeness. From an industry (macro‐level) perspective, product innovativeness positively moderates the mediating effect of KIMs on product innovation performance; in contrast, such a moderating effect is not significant under a firm (micro‐level) perspective.

This paper considers the implementation of a nonstationary, heterogeneous Markov model for the analysis of a binary dependent variable in a time series of independent cross sections. The model, previously considered by M offitt (1993), offers the opportunity to estimate entry and exit transition probabilities and to examine the effects of time-constant and time-varying covariates on the hazards. We show how ML estimates of the parameters can be obtained by Fisher's method-of-scoring and how to estimate both fixed and time-varying covariate effects. The model is exemplified with an analysis of the labor force participation decision of Dutch women using data from the Socio-economic Panel (SEP) study conducted in the Netherlands between 1986 and 1995. We treat the panel data as independent cross sections and compare the employment status sequences predicted by the model with the observed sequences in the panel. Some open problems concerning the application of the model are also discussed. 相似文献

The government of New Zealand is currently building a nation-wide fibre-optics network, a project known as the Ultra-Fast Broadband (UFB) initiative. The UFB network will cover 75 percent of New Zealanders over 10 years and will cost NZD $1.5 billion to the New Zealand government. The technical and economic characteristics of the new network will have a deep impact on the current landscape of the telecommunications markets. Institutional arrangements are in place for the development of the New Zealand's UFB: a government-owned agency, Crown Fibre Holdings (CFH); private investors who jointly with CFH own the Local Fibre Companies (LFCs) which will operate the UFB; and Retail Service Providers (RSP) that will provide end-user services by purchasing wholesale services to the LFCs. Relying on a normative economics approach that uses recent advances in the theory of platform-based markets with cross-network effects – also known as theory of two-sided platforms – the paper proposes a novel view of the way markets over the UFB will unfold. On one hand, the theory is used to explain the rationale behind regulatory decisions already made and their effect on the development of UFB-based markets for contents and services. Such analysis is followed, on the other hand, by the introduction of a simple taxonomy for the RSPs which provides the framework to argue about the most likely scenarios for service deployment and competition to develop over the UFB. The analytical framework reveals that the UFB ecosystem will be fraught with cross-network externalities which are the basis for regulatory decisions already adopted and the source of particular forms of strategic behavior adopted by the UFB-based market innovators. 相似文献

企业面对更多的挑战,要适应环境的变化,才能战胜挑战。国内外一些企业开始寻求一些新的管理方法,IPD就是其中之一,本文仅选取了IPD中一个核心—共用技术平台思想,用战略理论和观点,来分析其价值,以及在共用技术平台开发中的管理问题。初步阐释这种在国内还比较新的管理方式,希望能够让更多的学者和管理者能够关注并丰富这一理论。 相似文献

This study investigates whether relaxation of firms' financial constraints is an important outcome of the US cross‐listing mechanism. We use the association between investment spending and cash flow to test for the presence and importance of firms' financing constraints. Consistent with the bonding hypothesis, the results suggest that US exchange and private placement cross‐listings significantly alleviate firms' financing constraints. In addition, the financial benefits associated with exchange listings are larger than those associated with private listings, while on the other hand, over‐the‐counter programs do not improve capital allocation. The study also shows that US exchange cross‐listing benefits have not been eroded by the enactment of the Sarbanes‐Oxley (SOX) Act in 2002. Copyright © 2014 ASAC.
