区域知识产权保护发展的空间格局及结构体系研究

以我国各省知识产权保护制度为研究对象，创新性地将探索性空间数据分析方法与社会网络分析方法相结合，基于地理邻近视角，验证了区域知识产权保护的空间相关性、空间集聚特征和空间溢出效应。同时，突破地理近邻效应的局限，解析区域知识产权保护的空间关联特征。结果表明：我国各省知识产权保护具有全局自相关性，相似地区间存在空间集聚效应，不同发展程度地区的空间关联性质不同；网络化后的区域知识产权保护各节点间联系紧密、网络结构稳定，并且可以确定核心行动者和边缘行动者角色；长三角、珠三角、环渤海等较发达地区与其它地区之间存在较多溢出关系。     

Close relationship with the supervisor may impede employee creativity by suppressing vertical task conflict

Leader‐member exchange as a form of supportive leadership is expected to foster employee creativity. However, empirical evidence suggested this relationship is complex. This study attempts to address this complexity by proposing and testing a curvilinear mechanism, which attenuates the overall positive effect of LMX on creativity by transmitting a curvilinear indirect effect via vertical task conflict. Results drawn from a sample of 276 supervisor–subordinate dyads provided support for the hypothesized curvilinear indirect effect. Specifically, LMX was found to negatively influence employee creativity by suppressing vertical task conflict for subordinates in high‐quality LMX relationships, while the indirect effect was not significant for subordinates in low‐quality LMX relationships.     

International trade of GMO-related agricultural products

This paper examines the international trade of a variety of genetically modified (GM) food products over a 27-year period (1984–2011) with data from the United Nations using the tools of social network analysis. The results indicate that each of the different crops have a distinctive pattern of trade that has changed over time due to a number of different factors. Also, trade in agricultural commodities became more diversified over time, dominated less by the United States and other nations central in the trade networks and trade in the individual GM crops was stable over time. Countries maintained their trading partners for specific crops, despite the adoption of the genetically modified varieties. The economic implications of these results are discussed for specific countries.     

Board directors with foreign experience and stock price crash risk: Evidence from China

This study examines the impact of board directors with foreign experience (BDFEs) on stock price crash risk. We find that BDFEs help reduce crash risk. This association is robust to a series of robustness checks, including a firm fixed effects model, controlling for possibly omitted variables, and instrumental variable estimations. Moreover, we find that the negative association between BDFEs and crash risk is more pronounced for firms with more agency problems, weaker corporate governance, and less overall transparency. Our findings suggest that the characteristics of board directors matter in determining stock price crash risk.     

The Effects of Search-Related and Purchase-Related Mobile App Additions on Retailers’ Shareholder Wealth: The Roles of Firm Size,Product Category,and Customer Segment

Mobile channel additions have been shown to increase consumer-brand relationships, brand satisfaction towards and overall purchasing from a retailer, but what is less apparent is whether shareholders are fully rewarded for retailers’ mobile channel additions. Results from an event study on 115 announcements relating to mobile app additions of publicly traded U.S. retail firms between 2009 and 2016 indicate that the stock market responds generally positively to mobile app additions, but specifically to the two mobile app addition types. Stock market responses to search-related and purchase-related app additions are moderated by firm size, product category, and target customer age. For announcements of search-related apps, the market responds more positively to product retailers than to service retailers, and to small firms than large ones. For announcements of purchase-related apps, the market responds less positively to firms that target younger customers than firms who do not especially target them.     

我国炼油工业应实行改造与新建并举的方针

目前我国炼油工业的生产能力，特别是加工中东含硫油的能力严重不足，为适应国民经济发展的需要，扩大炼油能力十分必要，根据测算，2010年我国炼油工业的加工量应达到3亿吨，2020年达到4．5亿吨，若按开工率90％计，则2010年我国炼油能力应达到3．3亿吨，2020年达到5亿吨，因此，从现在开始的10年内，需新增炼油能力1亿吨左右，在下一个10年，即2010至2020年，还需新增能力1．5亿吨，根据我国国情，因地制宜，充分利用现有装置潜力通过技术改造来发展炼油工业是十分必要的，但是大型，先进，一体化是我国炼油工业今后发展的主要方向，兴建新厂可采用先进的工艺技术和新的管理机制，取得较高的经济效益，因此，我国炼油工业的发展实行技术改造与兴建新厂并举的“两条腿走路”的方针。     

市场制度与诚信

市场制度的基础条件之一是诚信,而市场制度又会对诚信产生一定的破坏作用.因此,抑制诚信缺失,除了需要市场经济自身不断的完善,还必须使用非市场的力量,并且采用灵活的政治和经济政策,以维持必要的社会诚信水平.

利率市场化对商业银行的七大影响

所谓利率市场化是指中央银行放松对商业银行利率的直接控制，把利率的决定权交给市场，由市场资金供求状况决定市场利率．市场主体可以在市场利率的基础上，根据不同金融交易和各自的特点自由决定利率。利率市场化要求政府放弃对利率的直接行政干预．但并不排除国家的宏观间接调控．即中央银行通过制定和调整再贴现率、再贷款率及公开市场买卖有价证券等间接调控手段形成资金利率。     

中小企业板的推出对我国创业投资的影响

2004年5月，中小企业板在深交所获准设立，一时间，围绕中小企业板对创业投资运作影响的讨论空前热烈。笔者认为，要研究中小企业板对创业投资的影响，就必须从创业板和创业投资的内在机理出发，来研究中小企业板的制度安排是否能保证二者形成良性互动，关键的就是要研究中小企业板在制度上离一个成熟的创业板有多远。目前，学者和业内人士普遍对中小企业板的作用不甚乐观，而近一年来的实践也似乎验证了这一观点，因此，加强中小企业板的制度建设，使之尽快过渡为创业板，已经成了管理者的当务之急。
