基于SGMM模型的融资结构与公司创新关系：理论分析 与实证检验

The Relationship Between the Financing Structure and the Corporate Innovation Based on SGMM Model: Theoretical Analysis and Empirical Test

摘要:

验证我国目前融资结构调整与公司创新的非线性关系。构建2种融资模式下的创新收益模型，同时基于CSMAR数据库中2007—2011年上市公司样本统计数据，采用系统广义矩估计（SGMM）方法，针对公司创新投入、产出与融资结构的关系进行实证研究。回归结果显示，融资结构与公司创新的关系曲线呈显著的倒U型，我国的融资结构比值明显低于最佳的“拐点值”，融资结构的市场导向有利于公司创新。
