【摘要】：银企关系是学术界和实务界关注的焦点之一,然而,国内学者鲜有探讨银企关系数量的影响因素。本文使用我国A股上市公司2006-2013年的银企关系计数资料,利用零膨胀模型对企业建立银企关系规模的影响因素进行了分析。研究发现:规模大、资产负债率高、获利能力强的公司倾向于建立更多的银企关系;企业的长期负债率、第一大股东持股比例,是否是国有产权属性和企业的经营风险与银企关系的规模(数量)显著负相关;信贷合约的期限和信贷金额与银企关系的数量显著正相关;进一步比较了零膨胀模型与Poisson回归、负二项分布回归模型等计数模型,统计检验显示,零膨胀模型比较适合零值过多和过度离散的数据结构资料。
[Abstract]:The relationship between banks and enterprises is one of the focuses of academic and practical circles. However, domestic scholars seldom discuss the influence factors of the relationship between banks and enterprises. Based on the counting data of the relationship between banks and enterprises in China's A-share listed companies from 2006 to 2013, this paper analyzes the factors influencing the establishment of the relationship between banks and enterprises by using the zero-inflation model. The study found that companies with large scale, high asset-liability ratio and strong profitability tend to establish more bank-enterprise relationships, and the long-term debt ratio of enterprises, the proportion of the largest shareholders holding shares, Whether the property of state-owned property right and the risk of enterprise are negatively correlated with the scale (quantity) of the relationship between bank and enterprise, the term of credit contract and the amount of credit are positively correlated with the quantity of relationship between bank and enterprise. Further, the zero expansion model and Poisson regression are compared. The statistical test shows that the zero expansion model is more suitable for the data structure data with excessive zero value and excessive dispersion.
