技术转移是将社会科技资源转化为实体经济效益的重要途径。当前,我国研究型大学技术转移渠道不畅、技术转移绩效不高、大学科技成果成功产业化“最后一公里”问题凸显。基于现实需求和研究缺口,构建组织模块化对研究型大学技术转移绩效影响的理论模型。在此基础上,收集我国38所研究型大学样本数据,采用SPSS24.0和AMOS软件进行结构方程路径分析,论证和检验组织模块化对于研究型大学技术转移绩效的影响机制。结果表明:组织模块化对研究型大学技术转移绩效具有显著正向影响;技术创新能力在组织模块化与技术转移绩效之间起显著中介作用;知识共享的调节作用主要体现在组织模块化独立性、响应性与技术创新能力之间的关系上,其对组织模块分工性与技术创新能力关系的影响作用不显著。 相似文献

This paper reviews the changes in Shuanghui’s operations after the Smithfield acquisition as well as transformations in China’s pork industries. As income grows and diets change, there has been an increasing demand for high-quality pork and more processed pork products. However, China’s swine and pork industries are still at an early stage of development as evidenced by the low market concentration, intensive use of labour, a proliferation of intermediaries, and low levels of technology. Bounded by the established consumer preferences for freshness and the status quo in the midstream and upstream segments, Shuanghui is in a slow process of upgrading its domestic operations with Smithfield’s leading brands, import of chilled and frozen pork, advanced technologies, and the vertically integrated business model after this acquisition. In particular, it remains unclear whether Shuanghui can follow Smithfield’s experience to establish stable and safe hog supplies by multiplying self-owned hog farms, maintain and expand its current contracts with large-scale commercial hog farms, or rely more on global sourcing of pork primarily from the U.S. 相似文献

This study attempts to broaden our understanding of the value relevance of environmental performance by providing empirical evidence on the moderating role of financial environmental reporting. Previous studies find that firms' environmental performance can be both positively and negatively associated with market value. Such contradictory findings can be attributed to the fact that environmental performance is associated with future economic benefits and costs. This study suggests that firms with recognized environmental provisions on their balance sheets enable investors to disentangle these opposite effects either by signaling strong future financial performance or by enhancing the reliability of environmental performance information. Regardless of the mechanism by which this moderation effect is invoked, it is hypothesized that capital market participants place a positive and significantly higher value on the environmental performance ratings of firms with recognized environmental provisions than on the ratings of firms without environmental provisions. Utilizing a sample of 692 firm-year observations of French listed firms and employing a linear price-level model that associates the market value of a firm's equity with its environmental performance, I provide empirical evidence to corroborate this thesis. In addition to contributing to the academic debate on the market valuation implications of environmental performance, this study intends to provide useful insights from a country that can be considered a pioneer of environmental reporting legislation; hence, it provides valuable lessons for other jurisdictions that are in the process of developing their sustainability reporting regulations. Finally, the findings of this study support the calls for more integrated reporting showing that the interaction of financial and non-financial information has market valuation implications. 相似文献

The omni-channel shopping phenomenon creates major challenges for brick-and-mortar stores to remain relevant and appeal to customers. A way to counteract these challenges is to offer customers a journey where in-store experiences enable them to encounter numerous physical and virtual touchpoints evoked by affective, cognitive, physical, relational, sensorial and symbolic responses. This study ascertained the customer journey activated by the experiences causing value and resulting in intentions to revisit a retailer specializing in outdoor apparel. Our web-based survey collected 300 valid responses for analyses. The statistical analyses confirmed a positive relationship between the customer in-shop experience factors and the shopping trip value experienced, which in turn mediated the relationship with intention to repatronage. Some conclusions are made and various suggestions for future research are recommended. 相似文献

This paper explores the importance of incorporating the financial leverage effect in the stochastic volatility models when pricing options. For the illustrative purpose, we first conduct the simulation experiment by using the Markov Chain Monte Carlo (MCMC) sampling method. We then make an empirical analysis by applying the volatility models to the real return data of the Hang Seng index during the period from January 1, 2013 to December 31, 2017. Our results highlight the accuracy of the stochastic volatility models with leverage in option pricing when leverage is high. In addition, the leverage effect becomes more significant as the maturity of options increases. Moreover, leverage affects the pricing of in-the-money options more than that of at-the-money and out-of-money options. Our study is therefore useful for both asset pricing and portfolio investment in the Hong Kong market where volatility is an inherent nature of the economy. 相似文献

Important changes have happened to the upstream segment of the coffee sector in Ethiopia - Africa’s biggest - in the last decade, as illustrated by the increasing adoption of improved production, harvest, and post-harvest practices. Upstream marketing has also improved and there have been large investments in processing capacity, shown by the extended coverage of wet mills. These improved practices are shown to be associated with positive impacts on coffee productivity and prices. Changes appear to be linked with multiple factors including local market reform, greater presence of public extension agents, high international prices, and a push for certification by international buyers. On the other hand, a combination of production (lack of improved seedlings, weather and disease shocks) as well as institutional issues (saving constraints and lack of vertical integration and traceability) have seemingly impeded more widespread uptake of improved practices and therefore better farm performance. The study illustrates the significant complexity in obtaining transformation at the farm level in these settings. 相似文献

供应链管理作为一种新型的企业关系管理模式在现代市场竞争中为企业生存与发展提供了一种工具。本文针对协作型企业供应链管理进行了研究。协作型企业供应链由于其业务联系上的紧密性与其他供应链有所不同,在生产计划制定上强调生产计划的一致性与协调性,核心企业与供应企业在生产计划制定方面的信息共享;在销售管理上强调企业与销售商集成式管理。 相似文献

The performance of service industries in Canada has been lower than that of good industries over the last four decades, with noticeable exceptions such as for railways and telecommunication carriers. Service industries were less economically (and technically) efficient in that they generated less output value (quantity) per hour worked (level and growth) or per combined unit of labour and capital (multifactor productivity growth) than good industries. The relative output price of services declined slightly over time compared with goods. At the disaggregated level, changing relative output prices were substantial and proved to be an important factor explaining the relative satisfactory economic performance of many service industries despite their low technical performance. Nevertheless, the output share of service industries increased over that period, sustained, mainly, by the growing recourse of all firms to outsourcing of services. 相似文献

The objective of this paper is to determine the best predictor of equity market crashes by focusing particularly on volatility and market liquidity. In finance, volatility has traditionally been regarded as the best measure of market risk. However, this paper shows that the forecast value of market liquidity, in particular our modified calculated market depth, predicts equity market crashes much more accurately than does the forecast values of EGARCH or Implied Volatility. 相似文献
