汇率波动对企业生产率的影响 ——基于中国工业企业数据的实证分析

目前学界对汇率波动对企业生产率影响的大多数研究文献在研究方法上都是假定完全竞争市场这一前提而忽略了对市场竞争结构的考虑。有鉴于此,将HHI衡量的市场结构因素纳入到实际汇率波动对企业生产率作用机制的分析中,并且运用面板数据分别对从事出口和不从事出口的企业进行实证分析,结果发现：（1）汇率升值对所有类型企业的生产率的直接影响均显著为负;（2）汇率升值会通过进口竞争效应显著提高国内竞争程度较弱的行业中非出口企业的生产率;（3）汇率升值会通过出口市场冲击显著降低国内出口企业的生产率,并且这种负面影响与企业所处行业的市场集中度和企业出口依存度正相关。

Synchronization of hybrid-coupled heterogeneous networks: Pinning control and impulsive control schemes

In this paper, the synchronization control problem is considered for the delayed hybrid-coupled heterogeneous networks, i.e., complex networks with nonidentical dynamical nodes. Some effective control schemes are designed under which the whole network is globally asymptotically synchronized to an arbitrary objective trajectory. By imposing the open-loop control on the whole network together with the feedback control only on a small fraction of the nodes, an easy-to-verify sufficient condition is derived to guarantee the asymptotic synchronization of the complex network under study. Furthermore, to decrease the feedback control gains, the idea of adaptive control scheme is combined together, and the verified conditions are further weakened. Finally, by introducing the impulses to the open-loop network and using the improved Halanay inequality, other novel synchronization criteria are developed for the complex network. Comparisons of the obtained theoretical results as well as the detail pinning schemes are also given. Numerical examples of the undirected scale-free network and the directed small-world network are illustrated to demonstrate the applicability and efficiency of the proposed theoretical results.     

Academic scientists’ affiliation with university research centers: Selection dynamics

University research centers have been institutionalized as a part of the science policy repertoire committed to strategic use of science and technology. Based on a representative sample of academic scientists and engineers in American research universities, this study investigates the selection dynamics, attempting to unfold the determinants of department-affiliated faculty members to be center affiliates. The findings suggest that university research centers select their affiliates on the basis of individual scientific and technical human capital. Scientists from prestigious departments are more likely to be center affiliates, so are prolific scientists, former postdoctoral scholars and the elder cohorts. In the meantime, university research centers are able to overcome the incentive incongruity with academic departments, as is evidenced by a higher likelihood among junior scientists to secure center connections. Dedicated to diversity and equity, university research centers provide a level playing field for women, minority and foreign-born scientists. The study concludes with a discussion of the scientific and technical human capital theory and policy implications in the science enterprise.     

企业国际化经营专利风险因素——基于专利属性的实证研究

从专利属性的视角出发,分析企业未来遭遇海外专利侵权诉讼的风险因素。以专利授权为分割点,将专利属性划分为品质属性和价值属性,运用权利要求数量、后向引用和专利家族三个变量描述专利品质属性,运用专利权维持、专利授权后审查、向前引用、专利权交易和专利权融资担保等变量来描述价值属性,进而分析专利品质属性、专利价值属性与专利侵权诉讼的关联;以中国企业在美国市场的专利侵权涉案专利为对象开展实证研究。结果表明:专利未来发生侵权的可能性,不仅与专利授权时的品质属性相关,同时与授权后专利运行中形成的新的价值属性相关;上述属性上的差异,可以帮助企业识别出市场上高风险专利,进而预测企业未来发生专利侵权诉讼的可能性。研究成果对于中国企业国际化经营中实施专利清查和专利风险预警有积极作用。
