开放式创新驱动制造业绿色转型了吗——一个有调节的中介效应模型

“双碳”目标和能源转型战略背景下,能否以及如何通过开放式创新驱动制造业绿色转型意义重大。根据2013—2020年中国内地30个省份面板数据,构建有调节的中介效应双向固定效应模型,探究开放式创新对制造业绿色转型绩效的影响效果及实现路径。结果表明,开放式创新通过提升技术研发能力、优化能源消费结构显著影响并提升制造业绿色转型绩效,其作用效果受到市场结构调节。异质性分析发现,双向开放式创新对制造业绿色转型绩效的作用存在差异,内向型开放式创新的驱动作用强于外向型开放式创新。研究可为中国制造业扩大创新优势、加速绿色转型提供政策参考与经验借鉴。     

交易成本经济学、组织失灵与管理会计研究

本文讨论了交易成本经济学中的制度、层级与企业边界等范畴对管理会计研究的基础作用,阐释了组织失灵理论的一些重要观点与管理会计研究的关系;认为管理会计是组织制度的一部分,交易成本经济学和组织失灵理论为分析管理会计的经济性质,进而为从制度与机制设计的角度认识管理会计系统的性质、功能与研究方法论等重要基础理论问题提供新的视野和机会。     

境外战略投资者引进对中国银行业监管的影响

引进境外战略投资者是中国商业银行改革的重要举措,然而加入WTO后外资银行的扩张行为给中国金融业带来了巨大压力。分析战略投资者的战略动机和行为表明,银行业控制权博弈对一国金融安全有重要影响。在现有开放条件下外资银行很难威胁到中国金融安全,但由于目前部分战略投资在中国区已表露出扩张雄心,应加强监管以维护中国核心金融利益。     

"油荒"的迷雾与启示

2007年9-12月,全国各个省市出现以柴油为主的成品油供应短缺现象.此次"油荒"的直接导火索是国际市场油价上涨;柴油收率及柴汽比均有下降,加之部分地方炼厂减产,是此次"油荒"出现的主要原因;占我国柴油消费量一半以上的非车用油消费受阻且价格长期失控,致使此次"油荒"波及范围之广、影响之大,前所未有."油荒"的出现是我国柴油供应长期紧张、成品油价格管理长期"畸形"的集中体现,它使我国长期存在的隐性石油市场浮出水面,证明政府对石油价格和资源配置的强势干预政策已经无法应对中国社会经济的市场化进程,必须进行改革."油荒"带给我们几点启示:一是减少燃料油进口、为合格的地方炼厂提供充足的原油,提高其装置能力利用率以补充市场成品油供应;二是运用税收工具而不是政府直接定价调控石油市场和消费;三是要实现石油价格市场化,就必须使现行市场结构逐渐向有限竞争并最终向充分竞争过渡.     

The diversification effects of volatility-related assets

We examine whether investors can improve their investment opportunity sets through the addition of volatility-related assets into various groupings of benchmark portfolios. By first analyzing the weekly returns of three VIX-related assets over the period 1996-2008 and then applying mean-variance spanning tests, we find that adding VIX-related assets does lead to a statistically significant enlargement of the investment opportunity set for investors. Our empirical findings are robust and have two implications. First, there is scope for the further development of financial products relating to volatility indexes. Second, hedge fund managers can utilize VIX futures contracts or VIX-squared portfolios to enhance their equity portfolio performance, as measured by the Sharpe ratio.

Energy Saving and Tourism Sustainability: Solar Control Window Film in Hotel Rooms

This paper investigates solar control film as an energy saver in the fast growing hotel sector in southern China. It investigates claims made for this low-cost retrofitted material in hotel rooms, calibrating reductions in solar gain in summer. It provides reliable and independent data about the performance and economic viability of solar control film in real hotel environments. The study found that, by limiting solar gain, the film helps limit tourism's impact on global warming and climate change. The paper also foreshadows new technical glazing developments.     

Cost structure and technological change of local public transport: the Kaohsiung City Bus case

This study has developed a translog cost function for the Kaohsiung City Bus (KCB) to analyse its cost structure and economic characteristics, based on monthly data over the time period from January 1996 to December 2000. The empirical results reveal that economies of density in the provision of bus services in Kaohsiung do prevail. The estimated marginal cost, which is less than the average cost but greater than the current bus fare, indicates that the subsidy is necessary. Due to the existence of returns to density (RTD), the KCB could obtain cost-saving benefits by extending its output scale. The KCB production technology is also not neutral. The effects of technological change on the KCB costs suggest that over the period 1996–2000 technological progress did lead to cost saving; the pure productivity growth rate increased from 0.45% in 1998 to 3% in 2000.     

Factors influencing the intentions of passengers regarding full service and low cost carriers: A note

This study investigates discrepancy in factors affecting passengers' intensions regarding using full service and low cost carriers. A conceptual model, that originally focused on the former, is adopted and slightly revised according to the service properties of low cost carriers. To validate the revised model, a questionnaire survey on passengers of Spring Airlines, the first low cost airline in China, was conducted. The results indicate differences in attitudes towards full service and low cost carriers. Service perception is a latent variable with the most significant influence on intentions about using full service carriers, but exhibits less effect on intentions regarding low cost operators. Conversely, service value exerts the greatest effect on intentions for possible low cost passengers.     

Negative affectivity and workplace deviance: the moderating role of ethical climate

This study investigates (1) the relationship between employees’ trait of negative affectivity (NA) and workplace deviance and (2) the moderating role of ethical climate in the above relationship. Data was collected from 310 employees in 40 Taiwanese companies, and hierarchical linear modeling was used to test the hypotheses. Results show that NA was positively related to workplace deviance. In addition, the rules climate weakened the relationship between NA and workplace deviance, and both the instrumental climate and the caring climate strengthened the relationship between NA and workplace deviance. Managerial implications and future research directions are also discussed.
