Tax incentive and corporate financial performance: Evidence from income tax revenue sharing reform in China

How to stimulate corporate performance is a crucial issue of general concern in all countries. This paper examines how China’s Income Tax Revenue Sharing Reform in 2002 affects corporate financial performance. Unlike general tax policies that directly adjust the nominal tax rate or depreciation allowance, this reform indirectly affects the effective Enterprise Income Tax (EIT) rate by switching tax administration, thereby affecting corporate financial performance. We use a firm-level data-set from Annual Survey of Industrial Firms (ASIF), and test the impact by using a quasi-natural experimental design through regression discontinuity design (RDD). We find that after the reform, the effective EIT rate (ETR) of enterprises collected EIT by State Administration of Taxation (SAT) was 10% lower than that of enterprises collected EIT by the Local Administration of Taxation (LAT). If the ETR reduces by 1%, corporate financial performance, more specific, Return on Asset (ROA), increases by 1.7%. There are two available channels: increasing fixed asset investment (FAI), and alleviating external financial constraints. Additionally, the impact can be weakened for locally SOEs, large firms, firms with low SA index and those in less competitive industries.
