国际金融危机后,金融改革虽然提高了全球金融体系的抗风险能力,但是其对企业产出增长的负面影响一直没有完全消除,仍在影响全球经济增长的力度及可持续性。本文运用2006~2016年中国A股上市公司年度数据,以创新投入能给企业带来增长为出发点,通过引入三种不同的企业融资方以及企业对创新研发的投入情况,探讨金融摩擦是如何通过融资传递到企业全要素生产率增长之中的。研究发现:(1)在中国,债权融资和股权融资的增长对全要素生产率的增长有显著影响,而内源融资增长不显著;(2)金融摩擦对生产率增长的传递方式主要是债权融资。随着金融危机的爆发,金融摩擦的增大导致生产率对债权融资的负效应更为敏感,企业生产率更易受到重创,生产率的下降反过来又会影响企业的再借贷,企业很容易陷入持续低迷增长的困境之中。

Alongside recent advances and booming applications of DNA sequencing technologies, a great number of complete genome sequences for animal species are available to researchers. Hundreds of animals have been involved in whole genome se- quencing, and at least 87 non-human animal species＇ complete or draft genome sequences have been published since 1998. Based on these technological advances and the subsequent accumulation of large quantity of genomic data, evolutionary genomics has become one of the most rapidly advancing disciplines in biology. Scientists now can perform a number of comparative and evolu- tionary genomic studies for animals, to identify conserved genes or other functional elements among species, genomic elements that confer animals their own specific characteristics and new phenotypes for adaptation. This review deals with the current ge- nomic and evolutionary research on non-human animals, and displays a comprehensive landscape of genomes and the evolution- ary genomics of non-human animals. It is very helpful to a better understanding of the biology and evolution of the myriad forms within the animal kingdom [Current Zoology 59 （1）： 87-98, 2013].

The measurement-result-conditioned evolution of a system(e.g., an atom) with spontaneous emissions of photons is described by the quantum trajectory(QT) theory. In this work we generalize the associated QT theory from an infinitely wide bandwidth Markovian environment to the finite bandwidth non-Markovian environment. In particular, we generalize the treatment for an arbitrary spectrum, which is not restricted by the specific Lorentzian case. We rigorously prove the general existence of a perfect scaling behavior jointly defined by the bandwidth of the environment and the time interval between successive photon *** a couple of examples, we obtain analytic results to facilitate the QT simulations based on the Monte-Carlo algorithm. For the case where the analytical result is not available, a numerical scheme is proposed for practical simulations.
