The impact of tax business environment on regional innovation: Evidence from China
1. Meaning & Introduction
Tax Business Environment refers to the overall structure of tax laws, policies, administration, and services that firms face when engaging in economic activity. It includes tax rates, complexity of procedures, digitalization of tax services, transparency, incentives for R&D, and ease of compliance. A favorable tax business environment reduces burden and uncertainty for enterprises, while a poor one increases costs, risk, and inefficiency.
In the context of China’s innovation-driven development strategy, the tax business environment is crucial. China has pursued reforms such as “Decentralization, Management and Service” to optimize the tax environment, aiming to make tax compliance easier, reduce transaction costs, and support enterprise growth and innovation. MDPI
Regional Innovation refers to the capacity of geographic areas (provinces, cities, clusters) to produce new products, technologies, patents, and processes. Innovation capability drives economic growth, employment, competitiveness, and long-term productivity.
2. Advantages of a Favorable Tax Business Environment for Regional Innovation
2.1 Boosting Innovation Efficiency
Optimizing the tax business environment has been shown to enhance enterprise innovation efficiency — the ability to convert inputs (R&D, talent, capital) into outputs (patents, new products). Empirical evidence from China’s pilot tax reforms shows that reforms significantly improved innovation efficiency in listed firms. MDPI
Mechanisms include:
-
Alleviating Financing Constraints: Better tax systems (e.g., smarter tax credit data sharing) help banks assess creditworthiness, widening access to funding. MDPI
-
Reducing Transaction Costs: Streamlined, digital tax procedures cut bureaucratic delays and compliance costs, freeing resources for innovation. MDPI
-
Digitalization Stimulus: Digital, intelligent tax services encourage firms to adopt digital technologies, fostering innovation ecosystems. MDPI
2.2 Promoting Investment and Entrepreneurship
Tax incentives and favorable environments improve the investment structure and attract capital into high-tech and innovative sectors. Research shows that tax incentives significantly enhance innovation and entrepreneurship outcomes across Chinese cities, partly by improving overall business conditions and encouraging fiscal expenditure toward science & technology.

2.3 Spillover and Regional Effects
A strong tax business environment in one region spills over to neighboring regions, reducing regional disparity and enhancing innovation capacity across clusters. Spatial interaction effects were documented in studies showing links between tax conditions and neighboring innovation performance. ScienceDirect
3. Disadvantages of Tax Business Environment on Regional Innovation
3.1 Distortions from Tax Structures
Some research finds that certain tax categories, like corporate income tax or high value-added taxes, may hinder innovation if they raise the overall tax burden or distort resource allocation. For example, corporate income taxes can reduce incentive for R&D investment by reducing net returns. MDPI
3.2 Uneven Benefits
Tax incentives often benefit larger and more innovation-endowed companies more (e.g., high-tech or capital-rich firms), leaving small and less-resourced firms behind. This can widen regional disparities if not properly designed. MDPI
3.3 Increased Tax Avoidance Behavior
Generous innovation tax incentives can sometimes lead to unintended consequences such as increased tax avoidance strategies, where firms artificially adjust financials to maximize benefits, ultimately reducing tax revenue without proportional innovation gains. ScienceDirect
4. Challenges in Linking Tax Business Environment to Innovation
4.1 Measuring Impact Clearly
Innovation outcomes are influenced by many factors beyond tax policy (e.g., human capital, infrastructure, financial markets). Isolating the direct effect of tax environment from other institutional factors remains challenging for empirical research.
4.2 Regional Imbalances
China’s vast regional diversity means that tax incentives may work very differently across provinces/cities (e.g., coastal vs central/western regions). Evidence suggests reforms have heterogeneous effects depending on local economic conditions, firm structures, and industry composition. MDPI
4.3 Unintended Consequences
Poorly targeted tax incentives can create rent-seeking behavior or distort investment towards tax planning mechanisms instead of productive innovation. Moreover, overly complex tax systems may still burden smaller entrepreneurs.
4.4 Fiscal Constraints
Lowering taxes to promote innovation reduces short-term government revenue, which can constrain public investment in R&D infrastructure and education unless compensated by broader fiscal reform.
5. In-Depth Analysis: Mechanisms Linking Tax Business Environment and Innovation
Below are core mechanisms identified in Chinese evidence:
5.1 Investment and Resource Allocation
A well-designed tax business environment steers capital toward innovation by lowering effective costs and improving expected returns. For example, easing financing constraints increases funds available for R&D, while reduced bureaucratic costs improve operational efficiency. MDPI
5.2 Structural Reform and Digitalization
China’s “Decentralization, Management and Service” reform not only simplified tax procedures but also integrated digital platforms that expedite information exchange between tax authorities, banks, and enterprises — facilitating smarter credit decisions and encouraging digital transformation. MDPI
5.3 Spatial Spillovers
Regions with more advanced tax business environments often attract talent, capital, and innovation clusters. These clusters generate technological spillovers to neighboring areas, reducing regional innovation gaps and reinforcing innovation ecosystems. ScienceDirect
5.4 Interactions with Other Policies
Tax reforms do not operate in isolation. Their effects interact with industrial policies, direct R&D subsidies, and broader business climate factors. For example, tax incentives are more effective when combined with robust science & technology fiscal support and streamlined administrative services. IDEAS/RePEc
6. Conclusion & Summary
In summary:
-
A favorable tax business environment in China promotes regional innovation by reducing barriers, incentivizing investment, and encouraging efficiency. MDPI
-
Key advantages include improved financing, lower transaction costs, digital transformation, and spillover effects that boost inter-region innovation capability. ScienceDirect
-
However, disadvantages like tax distortions, uneven benefits, and unintended avoidance behaviors pose challenges. ScienceDirect
-
Addressing measurement challenges, regional heterogeneity, and fiscal sustainability remain important for policy design.
Policy Implications: For tax policy to effectively nurture regional innovation, China should:
-
Continue simplifying and digitalizing tax procedures,
-
Tailor incentives to support SMEs and lagging regions,
-
Balance tax incentives with direct investment in R&D,
-
Monitor and mitigate avoidance strategies that undermine objectives.
This balanced approach can help strengthen China’s innovation ecosystems while maintaining fiscal health and equitable development.
