摘要
要素禀赋结构决定了中小企业是中国当前最优产业结构中的主要企业类型,中小企业存在融资约束也已然成为各界共识。然而遗憾的是,束缚中小企业发展的瓶颈至今没有突破。文章基于新结构经济学最优金融结构理论视角,以欧拉方程投资模型为基础,利用2006-2011年中小企业板上市公司数据和一阶差分GMM估计方法,系统考察了中小银行发展对于缓解中小企业融资约束的重要性。研究发现,银行中介与金融市场的比例构成、金融发展和贷款利率浮动这三个因素对中小企业融资约束具有重要影响的判断无法获得经验证据的支持,而中小银行发展则显著降低了企业投资对现金流的敏感性,有效缓解了中小企业融资约束。同时,稳健性检验表明,中小企业投资对现金流的敏感性源于融资约束而非代理冲突。文章的政策含义是,与推动总量上的金融发展及放松利率管制相比,以发展中小银行为核心内容的金融结构改革应在中国金融改革中占优先地位。

③我们在主成分分析中发现只有唯一的一个主成分的特征值大于1,方差比率为72.399%。我们将这个主成分的负荷系数除以其特征值的平方根获得权重系数。令X1、X2、X3和X4分别表示金融机构贷款/GDP、金融机构存款/GDP、股票市场市值/GDP以及股票市场成交额/GDP这四个原始指标的标准化形式,基于已获得的权重系数对这四个标准化指标进行加权平均,从而获得金融发展水平综合指数。具体而言,FD=0.468X1+0.549X2+0.506X3+0.472X4。
④为了检验工具变量的有效性,我们采用了m2检验、Sargan检验和Hansen检验,结果都支持选取的工具变量是有效的。
⑤国内一些文献为金融发展缓解企业融资约束提供了经验证据(朱红军等,2006;饶华春,2009;沈红波等,2010;解维敏和方红星,2011),但我们注意到这些文献并没有专门考察金融发展对缓解中小企业融资约束的作用。
⑥本文的研究结论与王东静等(2007)不一致。王东静等(2007)的研究存在的问题是,在比较取消贷款利率上限前后企业的负债水平时缺乏参照组。另外,他们的研究利用的是A股上市公司数据,所涉及的中小企业只是大企业中规模相对较小的企业。
