金融发展、银行关联与民营企业贷款研究

依据2010~2012年957个民营上市公司的面板数据，考量金融发展、银行关联与民营企业贷款之间的关系。结果发现，在金融发展不均衡的背景下，民营企业会通过银行关联来获得更多的贷款数额，特别是在金融发展水平相对较低的地区，银行关联对民营企业贷款的影响更加显著。因此，金融市场监管者应进一步深化金融体制改革，加快落后地区金融市场化的进程，拓宽民营企业融资渠道，降低民营企业融资成本。     

Advancing research on urban greenspace experiences and perceptions in disadvantaged communities: A social housing perspective

Empirical assessments of the experiences and perceptions of urban green space (UGS) in a social housing context are scant. Studying UGS perception in these contexts is important to understand how people experience and derive benefits from UGS in disadvantaged communities. This short communication provides interdisciplinary and methodological guidance on how to conduct empirical assessment of UGS experience and perception in social housing neighborhoods. For conducting these types of studies, we suggest researchers go beyond simply calculating UGS abundance around communities and consider assessing UGS experiences and perceptions. We suggest designing studies that account for the mixed nature of many social housing communities and that develop useful UGS perception measures that can be associated with wellbeing and community indicators. Finally, we also recommend: (1) designing studies at the local scale and developing strong relationsihps with the social housing communities before and while conducting these studies; (2) considering safety as a key component of UGS perception measures; (3) considering the association between UGS perception measures and wellbeing and community experience indicators to strengthen existing models of UGS benefit provision.     

投资者保护、大股东持股比例与现金持有量

以2005～2011年沪深两市A股391家上市公司为样本研究投资者保护、大股东持股比例和现金持有量的关系，研究结果表明，大股东持股比例与现金持有量间呈倒“U”型关系。进一步按照投资者保护程度的高低对样本进行分组，研究发现，当大股东持股比例小于48%时，投资者保护程度高的组，大股东持股比例和现金持有量呈显著正相关关系；当大股东持股比例大于48%时，投资者保护程度高的组，大股东持股比例和现金持有量呈显著负相关关系。
