2  MATERIALS AND METHODS 
2.1  Corporate Financialization 
In the research on the causes of enterprise 
financialization, there are mainly two viewpoints: 
"reservoir" theory and "investment substitution" 
theory. According to the "reservoir" theory, when 
enterprises invest idle funds into the financial 
industry, they can use financial derivatives to hedge 
trading risks and prevent the risk of capital chain 
breakage. In the face of future investment 
opportunities, they can withdraw large amounts of 
funds in time to reduce investment underinvestment 
(Stulz, 1996; Bessembinder, 1991). Due to the strong 
liquidity ability and low realization cost of financial 
products, financial products held by enterprises can 
play the role of funds, and can quickly replenish 
funds when enterprises need funds to achieve the 
"reservoir" effect.   
"Alternative investment" phenomenon appeared 
in the 1970s last century, America's economy 
contracted phenomenon, most of the entity enterprise 
losses, industrial investment yields down, enterprise 
in order to get more rewards, maximizing benefits, 
meet the requirement of maximize shareholder 
returns, and had to put resources into other areas 
(Stockhammer, 2006).   
2.2  Financing Constraints 
According to the definition of relevant scholars, 
financing constraint is due to the imperfect market 
mechanism and other problems, which leads to the 
higher external financing cost than the internal 
financing cost (Fazzari, 1988). More and more 
scholars have noticed that enterprises are faced with 
different degree of financing constraints and the 
problems brought by financing constraints have 
become a research hotspot. Some scholars have 
found that enterprises facing financing constraints 
will reduce innovation ability, hinder the process of 
upgrading of global value chain, restrict the 
participation of enterprises in export, and affect the 
investment and growth of great business 
(Schumpeter, 2003; Gorodnichenko, 2013; Stein, 
2003; Sun Lingyan and Cui Xijun, 2012). 
Some scholars have found that political 
association can alleviate the financing constraints of 
Chinese enterprises, and equity incentive can also 
reduce the negative impact of financing constraints 
(Yan Ruosen and Jiang Xiao, 2019; He Xiaoxing and 
Ye Zhan, 2017). However, the existing literature has 
not been able to provide sufficient evidence to 
support the question of whether corporate 
financialization can affect the financing constraints 
of enterprises. 
2.3  Research Hypothesis 
2.3.1  Corporate Financialization and 
Corporate Financing Constraints 
In the process of production and management, 
enterprises face the biggest problem is the problem 
of capital chain fracture. How to obtain a large 
amount of low-cost capital when the enterprise is in 
urgent need of capital is the key factor for the 
development and growth of enterprises. Some 
scholars have found that the flexibility of financial 
assets, compared with production investment, can 
enable enterprises to gain profits quickly in the short 
term and expand the cash flow of enterprises (Ran 
and Duchin, 2010). Enterprises will invest their idle 
funds in the financial industry to improve their 
financialization and gain more profits, avoid capital 
chain fracture caused by insufficient operating profit, 
avoid risks and increase their ability to respond to 
emergencies (Gehringer, 2013; Easley D, O'Hara M, 
2004). The main motivation of the improvement of 
corporate financialization is the "reservoir" effect, 
which can effectively alleviate the financing 
constraints of enterprises. Based on this, hypothesis 1 
is proposed in this paper: 
H1: The improvement of enterprise 
financialization can effectively alleviate the problem 
of enterprise financing constraint; 
2.3.2  Adjust Action of Property Right Nature 
Debt financing is the main financing channel in 
China. Due to policy, environment and other factors, 
state-owned banks play a dominant role in the 
financial system, and financial resources also flow 
more to state-owned enterprises. Non-state-owned 
enterprises are faced with more serious letter of 
credit policy in the process of applying for loans 
(Easley and O'Hara, 2004; Li Jian and Chen 
Chuanming, 2013). It is difficult for non-state-owned 
enterprises to obtain loans from financial institutions. 
In order to alleviate the problem of financing 
constraints, they will invest part of their funds in the 
financial industry, because the "reservoir" effect of 
financialization is stronger than the crowding out 
effect, which will broaden the financing channels of 
enterprises and improve their financing capacity (Wu 
and Zhang 2021). Based on this, hypothesis 2 is 
proposed in this paper:
