智慧专业化视角下区域资源集聚与区域创新驱动发展

传统发展动力逐渐式微，创新驱动成为区域经济发展的新引擎。走创新驱动发展道路，需要新的经济理论解释、构建并指导各区域经济增长方式和发展模式转型。智慧专业化是一种新兴经济理论，能够较好解释区域创新驱动发展的内在动力。智慧专业化有效支撑区域资源集聚与区域创新驱动发展相关性研究，从资源内存性和外向性、资源技术和经济属性以及资源支持程度3个方面，论述区域创新驱动发展的动力来源与动力持续性，进而解释区域创新驱动发展资源集聚对区域创新驱动发展绩效的影响。     

国企民营化与企业创新效率：促进还是抑制?

文章基于混合所有制改革的背景，从创新效率的视角考察了微观创新主体民营化前后创新行为的变化。研究发现，民营化抑制了企业的创新效率，企业的专利数量显著减少，这种影响在缺乏原国有大股东制衡、无系族的上市公司以及外部产权保护较弱的地区更加显著，而且相对于创业型企业，民营化企业的创新效率更低。进一步研究发现，民营化抑制企业创新效率的一个重要途径是关联交易显著增加、投资显著减少，民营化后非国有大股东更多地表现出掏空动机，减少了创新活动，降低了创新效率。文章的研究结论为理解民营化企业的效率提供了新视角，有助于我们正确认识和理解新兴转轨经济体的民营化行为，而且对于监管层如何推进混合所有制改革具有重要的政策启示。     

Industry competition in China: an external governance mechanism or an external incentive

We focus on the impact of industry competition on earnings management in listed companies in China. Empirical analysis reveals the following: (1) When competition within an industry is relatively low, it lowers the extent of earnings management; (2) when competition is relatively high, earnings management is promoted.; (3) within an industry, the more intense the competition, the more companies manipulate earnings when in an inferior competitive position; and (4) state‐owned enterprises that are at a competitive disadvantage within an industry rely more on real earnings management strategies, whereas these effects are insignificant in private firms.     

房地产抵押品价值变动的实体经济效应

在我国较密集的房地产调控背景之下,定量测算房地产抵押品价值变动对实体经济的影响幅度具有重要意义.文章采用前沿方法深入考察了房地产抵押品价值变动对公司投融资决策的影响,并在此基础上对房价调控政策对社会总投资的潜在影响进行了估算.研究发现:(1)我国存在显著的抵押品效应,公司房地产抵押品价值每上升1元,资本支出随之增加约5.7分;无论是控制公司固定效应,还是使用替代指标或子样本分析,抵押品效应均稳健成立.(2)宏观层面上,房地产抵押品价值1％的上升将引起总投资增加约466.3亿元.(3)对资金来源的探究显示,抵押品升值提高了公司的贷款获得,尤其是短期贷款的获得.(4)抵押品效应与公司的融资约束正相关,但与所在地区金融市场化水平无明显关系.基于研究结论,建议政府在进行调控时不宜对房价过度打压,而应引导房价保持与居民消费价格相当的增长速度,减少房价过度波动,维持房地产市场长期平稳健康发展.     

2014年大陆桥运输情况分析

2014年,世界经济尤其是欧盟们经济持续低迷、我国国内经济发展增速放缓已处于"新常态"发展。大陆桥国际运输较往年呈现出一派欣欣向荣的景象,虽然国际过境运输量有所下滑,但整体情况尤其是中欧班列发展迅猛。这主要得益于我国以及亚欧国家对丝绸之路经济带建设的重视和积极参与。2014年,世界经济尤其是欧盟们经济持续低迷、我国国内经济发展增速放缓已处于"新常态"发展。因此,2014年我国交通运输经济运行虽然总体发展平稳,但增速趋稳。港口生产有所放

The information content of option-implied volatility for credit default swap valuation

Credit default swaps (CDS) are similar to out-of-the-money put options in that both offer a low cost and effective protection against downside risk. This study investigates whether put option-implied volatility is an important determinant of CDS spreads. Using a large sample of firms with both CDS and options data, we find that individual firms’ put option-implied volatility dominates historical volatility in explaining the time-series variation in CDS spreads. To understand this result, we show that implied volatility is a more efficient forecast for future realized volatility than historical volatility. More importantly, the volatility risk premium embedded in option prices covaries with the CDS spread. These findings complement existing empirical evidence based on market-level data.
