Small and medium-sized enterprises (SMEs) were an important part of China's economy, but they faced challenges to growth due to financing difficulties. Government subsidies are considered as a potential way to address this problem. This study aims to assess the effectiveness of the Chinese government's subsidy program aimed at improving the accessibility of financing for SMEs. We analyze a comprehensive dataset of Chinese firms' subsidy programs from 2011 to 2020. We classify subsidies into unconditional and conditional categories and use fixed-effects regression models to control for the effects of time and between-group variation to more accurately assess the effectiveness of government subsidies. In addition, we use a PSM-DID model to reduce the effect of selectivity bias to more accurately estimate the causal effect of subsidies on financing strategies. We also use a mediated effects model to help understand the mechanisms by which different types of subsidies affect financing strategies. The results show that government subsidies can significantly improve SMEs' financing ability, but different types of subsidies produce subtle differences. Conditional subsidies support debt financing mainly through incentives, while unconditional subsidies help SMEs improve their equity financing ability through information effects. Furthermore, we find that over-reliance on a single subsidy type may reduce its effectiveness, suggesting a complex relationship between government intervention and SME financing. Thus, well-designed policies are crucial for promoting SMEs and fostering economic growth.
中小企业是中国经济的重要组成部分,但由于融资困难,它们面临着增长挑战。政府补贴被视为解决这一问题的潜在途径。本研究旨在评估中国政府旨在提高中小企业融资可及性的补贴计划的有效性。我们分析了2011年至2020年中国企业补贴计划的综合数据集。我们将补贴分为无条件补贴和有条件补贴两类,并使用固定效应回归模型来控制时间效应和组间差异,以更准确地评估政府补贴的有效性。此外,我们使用倾向得分匹配法-双重差分模型来减少选择性偏差的影响,以更准确地估计补贴对融资策略的因果效应。我们还使用中介效应模型来帮助理解不同类型补贴影响融资策略的机制。结果表明,政府补贴可以显著提高中小企业的融资能力,但不同类型的补贴会产生细微差异。有条件补贴主要通过激励措施支持债务融资,而无条件补贴则通过信息效应帮助中小企业提高股权融资能力。此外,我们发现过度依赖单一补贴类型可能会降低其有效性,这表明政府干预与中小企业融资之间存在复杂的关系。因此,精心设计的政策对于促进中小企业发展和推动经济增长至关重要。
