城市蔓延真的抑制城市创新空间集聚吗

利用我国地级市面板数据，分别基于创新效率、知识溢出、就业匹配3种机制，解析城市蔓延对城市创新空间集聚的影响效应。研究发现：城市蔓延普遍对城市创新空间集聚产生负向全局处理效应，但经过创新效率、就业匹配以及知识溢出机制的调节后，该负向效应可以得到缓解甚至扭转。当城市蔓延导致城市就业密度、基础设施或工资水平下降时，则可能加剧这种负向效应；相对其它城市，东部地区或规模较大城市的城市蔓延会对创新空间集聚发挥提升效应。     

Sustaining Competitive Advantage Through Corporate Environmental Performance

This research investigates the relationship between a firm's environmental efforts and the sustainability of its competitive advantage by analyzing the effects of change in firm environmental performance on the persistence of profitability growth. We find that environmental resources allow a firm with superior financial performance to sustain its competitive advantage, and also complement the efforts of a poorly performing firm to hasten recovery from inferior financial performance. Our findings further indicate that firms attain such positive effects through enhanced profit margins resulting from improved environmental performance. Additionally, we observe that a corporate strategy of improving environmental performance demonstrates management's responsibility to maximize the shareholder wealth of a well‐performing firm. The results provide valuable insights to align environmental activities towards developing unique resources for sustaining the competitive advantage. The study provides an empirical support for creating economic value by benefiting the environment. Copyright © 2016 John Wiley & Sons, Ltd and ERP Environment     

In-flight physical surroundings: quality,satisfaction, and traveller loyalty in the emerging low-cost flight market

The purpose of our research was to investigate the relationships among overall service quality, customer satisfaction, and behavioural intentions by considering the moderating impact of in-flight ambient conditions (air quality, temperature, odour, and noise) in the low-cost airline industry. A survey was conducted on international flights. Results of the structural equation modelling from a sample of 402 passengers indicated that quality and satisfaction are significant drivers of intentions; and satisfaction acted as a significant mediators. Additionally, supporting the moderating impact of ambience, findings from the tests for metric invariance revealed that the effect of satisfaction on intentions was stronger for the high air quality, temperature, odour, and noise groups than for the low groups; and the strength of the relationship between quality and intentions was greater in the high noise group than in the low noise group. Our results will help practitioners/researchers develop effective strategies/theories for passenger satisfaction and retention.

对杠杆收购应用于油气上游行业的探讨

杠杆收购是仅以少量自有资金,主要依靠债务资本收购目标公司股权的一种收购方式.杠杆收购对于筹资企业和金融机构都有明显的优势和吸引力.要成功实施杠杆收购,企业必须经营稳定、负债较少、现金流稳健.杠杆收购的资金来源包括优先债、次级债和自有资金.私募股权基金以其高效的投资方法和运作模式,对杠杆收购的发展起到了关键的推动作用,已成为杠杆收购活动的主体.私募股权基金对于油气上游项目进行股权投资和杠杆收购,应从资源评估出发,充分考虑资源国的财税条款等因素,在此基础上建立经济评价模型,综合分析被收购企业的未来经营和盈利情况.杠杆收购的核心是对被收购企业的负债能力进行细致的测算,进而设计合理的资本结构,尤其是负债结构.杠杆收购方式使得私募股权基金以较少的自有资金,通过融债方式收购较大的企业,并可能实现丰厚回报.在收购过程中,风险的控制和防范十分必要.
