创新要素配置在投入产出两个环节中生成大量不完全技术信息,投入产出效率随机变动更加明显。从投入产出数据集合中提炼共同因子,与不可观测变量构成预测器,建立因子增广向量自回归模型(FAVAR),分析随机变动方差构成,测度投入产出效率随机变动程度。随机变动效应包括水平效应、稳定性效应和规模效应。投入产出效率自回归扰动项表示随机变动程度,将其细分为共同因子,计算预测器方差及其与投入产出效率的协方差。基于669家上市公司月度、季度、半年度和年度技术研发数据,比较分析投入产出效率随机变动程度及形成原因,引入脉冲响应法分析变量方差构成与变动特征,提出相关政策建议。 相似文献

研究目标:测算中国分行业的能源回弹效应与综合能耗系数。研究方法:通过编制含能源实物流量的价值型能源投入产出可比价序列表,测算出能源回弹效应与综合能耗系数,结合行业综合能耗情况分析了能源回弹效应的行业异质性。研究发现:各行业在能耗方面表现迥异,能源回弹效应也存在典型的行业异质性;中国整体经济能源回弹程度并不高,能效改善可以有效节约能源,但整体经济低能源回弹的表象也掩盖了部分行业能源效率无改善和高能耗行业高能源回弹的事实。研究创新:从系统与结构的视角审视了行业的综合能耗情况,并给出了一种基于能源投入产出表的能源回弹效应计算方法。研究价值:有助于提出整体经济结构优化与节能减排的行业政策。 相似文献

In this conceptual article, the authors propose a framework for how progressive human rights outcomes may be obtained in the context of bidding, planning and implementing major sport events (MSEs) through the implementation of four pathways, including good governance, the democratic participation of stakeholders, the formalisation of human rights agendas and the deployment of sensitive urban development. The authors argue that there is a need for adherence to internationally recognised standards, such as the Universal Declaration of Human Rights and the United Nations Guiding Principles on Business and Human Rights if rhetorical statements from MSE awarding bodies and host organisers are to be accountable to a wider set of actors. If researchers and practitioners want to address some of the critical issues related to human rights and MSEs, it is imperative that key actors working in the rights sphere are involved in shaping the research agenda and monitoring its implementation. Academics need to take a proactive approach aimed at achieving both theoretically grounded and practically relevant solutions, with engagement occurring over an extended period of time. This approach, avowedly political and concerned with genuine action, is a key way in which MSE stakeholders can be held to account for their actions in regard to human rights. 相似文献

The creation of the Asian Infrastructure Investment Bank (AIIB)was welcomed by the World Bank but opposed by the Obamaadministration. The paper explains China’s positive relationshipwith the Bank and the Organization for Economic Cooperation andDevelopment (OECD) in terms of the mission of the Bank, sharedby the OECD, to develop and deepen the global economy. The AIIBand the related Belt and Road initiative promise to do this throughinvestment in infrastructure and connectivity in and around thepoorly integrated Eurasian landmass. But while the current Chineseleadership has supported an inclusive global economy based uponfree trade and supported by multilateral institutions, China’s controlof resources outside the multilateral framework and adherence topractices that challenge liberal principles prompt suspicions thatthese commitments are either disingenuous or anyway subjectto reversal. In itself, therefore, the AIIB provides no conclusiveevidence either way on China’s future course. 相似文献

ABSTRACTWe propose a new approach for tracing the so-called ‘value-added-(re)distribution-important coefficients’ (in short the VARDI coefficients) in a world input–output model. From the perspective of a selected group of economies, VARDI coefficients may be defined as those elements in world input–output matrix in the case of which a small change in their levels leads to the maximization of a share of this group of economies in value added in global value chains. Due to the rapid development of the World Input Output Database, this approach may be easily applied in empirical research to different groups of countries and sectors in world IO models. In an illustrative empirical case study, we use the new approach in order to answer a question regarding what the main directions of the future macroeconomic policy of the U.S. could be in order to ensure the maximization of the country’s share in global value added. 相似文献

This study develops the AIEDA tourism advertising effects model and examines this model by tourism destination types and advertising formats in a field experiment. The AIEDA model extends the traditional AIDA model in the advertising field and additionally considers the unique features of tourism products. It includes five hierarchical stages: Attention→ Interest→Evaluation (Perceived Usefulness→ Perceived Credibility) → Desire →Action. Findings of experimental research indicate that destination type and advertising format have main effects and interaction effects on tourism advertising effects. In addition, this study discovered that, for natural and cultural destinations, video ads yielded similar or more positive advertising effects than virtual reality ads, whereas print was the least effective advertising format. 相似文献

现有关于网络环境下开放式创新的研究大都聚焦于内向型开放式创新,对于外向型开放式创新的关注不足。为更加真实地展现创新网络中知识创新、创新输出的整体行为机制,基于小世界网络仿真建模方法,从创新输出企业视角,探究创新输出与创新网络、创新绩效之间的内在关系。结果发现:网络关系强度、创新开放度与网络整体知识水平呈正相关关系,而个体网络规模与网络整体知识水平呈非线性相关关系;网络关系强度与网络知识水平分布均匀性呈正相关关系,创新开放度、个体网络规模与网络知识水平分布均匀性均呈非线性相关关系;当企业创新能力较强、解吸能力较弱时,网络整体知识水平和网络知识分布差异较大。创新输出企业可以结合网络结构和网络关系,优化创新网络、主体能力与创新开放度,制定开放策略,从而实现获取创新收益与保持自身竞争优势的双重平衡。 相似文献

Although the literature underlines the importance of finance in international trade, no prior study has examined the causal links between market power in banking and export performance. Using a world sample over the 1997-2010 period, and accounting for both observed and unobserved country heterogeneity, we find a positive effect of bank market power on exports, especially in high-income countries. We also document that this export-enhancing effect is more potent in informationally opaque markets. Our findings accord with information hypothesis which suggests that market power in banking induces stronger bank-firm relationships which can generate benefits for both borrowers and lenders. Policy interventions should, therefore, promote the supply of relationship lending as a means to mitigate informational asymmetries in the export market. 相似文献

AbstractUsing a hand-collected dataset, we examine share trading activity over the period 1882–1920 for the North British and Mercantile Insurance Company, one of the largest UK companies of the time. Our main finding is that the steady flow of rentiers into the shareholding constituency of this company stymied share trading activity. Another important finding is that share trading still occurred during the closure of the stock exchange in 1914, but on a much-reduced scale. We also find that there was a substantial boom in share trading and in insurance stock prices after World War I. 相似文献
