The effect of corporate governance on debt financing cost of listed companies

In recent years,bank credit business is booming with the increasing borrowing intention of China’s listed companies,and debt financing has become the major approach among listed companies’financing strategies.As a series of institutional arrangements about rights,responsibilities and benefits between different shareholders,corporate governance mechanism has a significant influence on the cost of debt financing.This paper employs variable coefficient panel data model to investigate the relationship of the listed company’s debt financing costs and corporate governance mechanism in terms of structural characteristics and time series characteristics.The results show that optimizing the structure of both Board of Directors and Board of Supervisors,establishing a reasonable management incentive system and reducing the concentration of ownership properly can directly contribute to a lower company’s debt financing costs.Meanwhile,property rights have an interactive influence on corporate governance from four aspects,which indirectly effect in company’s debt financing costs.     

Science Letters: A new quantitative model of ecological compensation based on ecosystem capital in Zhejiang Province, China

Ecological compensation is becoming one of key and multidiscipline issues in the field of resources and environmental management. Considering the change relation between gross domestic product (GDP) and ecological capital (EC) based on remote sensing estimation, we construct a new quantitative estimate model for ecological compensation, using county as study unit, and determine standard value so as to evaluate ecological compensation from 2001 to 2004 in Zhejiang Province, China. Spatial differences of the ecological compensation were significant among all the counties or districts. This model fills up the gap in the field of quantitative evaluation of regional ecological compensation and provides a feasible way to reconcile the conflicts among benefits in the economic, social, and ecological sectors.

Ni-Si合金材料与Ni-Si/C复合阳极材料的结构和电化学性能研究

采用大气熔炼-机械球磨二步法制备一系列Ni-Si合金材料和Ni-Si/C复合材料,并运用X射线衍射XRD、场发射扫描电子显微镜FE-SEM和恒电流充放电等测试方法对Ni-Si合金材料和Ni-Si/C复合阳极材料的结构和电化学性能进行了研究.结果表明,Ni-Si合金材料的放电比容量随着Si含量的增加呈上升趋势,但第1周材料充放电的库仑效率下降;采用炭包覆法制备的Ni-Si/C复合阳极材料与Ni-Si合金材料相比,其电化学循环性能大幅度提升,Ni-Si/C复合阳极材料第10周放电比容量保持分数是Ni-Si合金材料的6倍左右,这是因为机械球磨使炭粉均匀地分布在合金颗粒之间,提高了复合阳极材料的导电性.     

Standard molar enthalpy of formation of uniform CdMoO4 nano-octahedra

Controllable synthesis of uniform and single-crystalline CdMoO4 nano-octahedra has been successfully realized at large-scale by a facile reverse-microemulsion route at room temperature. The structures, compositions and morphologies of the as-prepared products were characterized in detail by X-ray powder diffraction (XRD), field-emission scanning electron microscopy (FE-SEM) and transmission electron microscopy (TEM), respectively. According to the thermochemical cycle, the relationship between the standard molar enthalpy of formation of nano-CdMoO4 and bulk CdMoO4 was proposed for the first time. In combination with micro-calorimetry, the standard molar enthalpies of formation at 298.15 K of as-ynthesized CdMoO4 nano-octahedra were ob-tained.
