摘　　要：小微企业是经济社会发展活力的微观基础,降低小微企业债务负担,推动小微企业可持续和高质量发展具有重要现实意义。税收优惠是国家支持小微企业发展的重要举措,但目前减税政策的效果如何尚不明晰。本文利用全国税收调查数据,基于小微企业所得税减半征收政策带来的冲击,使用群聚(bunching)方法考察了减税激励对小微企业债务规模和融资成本的影响。研究结果表明,所得税减半征收政策有效降低了小微企业的实际税负,部分企业通过操纵应纳税所得额享受到了税收减免,并使得操纵区间内的企业平均所得税负降低了6.83%。反事实估计减税的政策效应发现,企业所得税负每下降10%,则其流动负债会平均降低16.62%,流动负债占比降低1.65个百分点,同时企业利息支出下降21.9%,财务费用下降16.86%,这为减税政策缓解企业债务负担及化解杠杆风险提供了微观证据。在此基础上,本文还讨论了减税政策的动态效应及对企业生产效率的积极影响。本文研究结论表明,减税政策显著降低了小微企业税收负担,缓解了企业融资约束,这为国家进一步实施小微企业减税政策提供了经验支持。Small low-profit enterprises are an important foundation of the national economic development,and play a crucial role in absorbing employment,stimulating innovation,and promoting investment and consumption.Supporting the development of such enterprises is a key way to enhance economic vitality and realize high-quality economic development.However,financing difficulties,financing cost,and financing structure are the outstanding problems for such small low-profit enterprises because of their size and poor operational stability.Reducing these firms'debt burden has great practical significance in promoting sustainable,high-quality development.Tax preference is an important step to supporting the development of China's small low-profit enterprises.The Enterprise Income Tax system,which came into effect in 2008,sets the income tax rate for ordinary enterprises at 25%,whereas specified small low-profit enterprises enjoy the preferential tax rate of 20%.To further encourage the development of such enterprises,China implemented a policy of halving the income tax of smaller enterprises to a rate of 10%.This standard of halving the income tax increased the threshold from RMB30,000 in 2010 to RMB3 million in 2019,allowing more small enterprises to enjoy tax relief.However,it remains unclear whether the large-scale tax cut policy has improved the development environment and the development quality of these small low-profit enterprises.Small low-profit enterprises manipulate taxable income according to policy standards,which leads to the failure of the traditional causality identification strategy(DD/RD).Our study uses the National Tax Investigation Data from the Chinese State Administration of Tax(SAT),and applies the bunching method to construct a causality identification strategy.We estimate the counter-factual distribution and empirically examine the influence of tax reduction incentives on the debt size,debt structure,and financing cost of small low-profit enterprises.The study comes to the following conclusions.The half-
