First, the green credit policy has a significant
financing penalty effect. Green finance measures
require commercial banks to strictly control the
direction and scale of credit and curb the lending
space for polluting projects, Thus, heavy polluting
enterprises face higher financing threshold and
financing cost (Liu, et al., 2019; Chen, 2019).
According to Su Dongwei and Lian Lili (Lian 2018),
the financing decisions of enterprises are greatly
affected by the supply of financial markets. The
increase of credit threshold has significantly reduced
the long-term debt financing of heavily polluting
enterprises. On the one hand, under financing
constraints, heavily polluting enterprises lack funds
to carry out projects, so they may change from
prospectors to defenders and adopt a more
conservative enterprise strategy. On the other hand,
considering the obvious capital oriented mechanism
in the green credit policy, heavily polluting
enterprises may tend to change their development
mode and find a new way out (Wang, 2021, Wang,
2021), so they may choose a more radical enterprise
strategy and change from defender to prospectors.
Second, the green credit policy has an investment
restriction effect on heavily polluting enterprises.
Under the green financial measures, the financial
asset allocation of heavily polluting enterprises is
interfered by the government and the market, and the
financing cost of non green projects increases.
Therefore, the inefficient investment of enterprises,
especially over investment, has decreased
significantly (Wu, et al., 2012). In addition, the green
credit policy requires heavily polluting enterprises to
reduce pollutant emissions and improve their
environmental governance capacity. Under the
condition of limited financial resources,
environmental governance investment must have a
"crowding out effect" on productive investment in the
short term (Wang, etc. 2021). The investment of
heavy polluting enterprises is limited, and the
enterprise strategy may tend to be conservative.
However, from the perspective of transformation and
development, facing the dilemma of double
restrictions on financing and investment, heavy
polluting enterprises may increase green investment
in order to find a new development outlet (Wang, etc.,
2021), making the enterprise strategy from
conservative to radical.
Third, the green credit policy will bring greater
public pressure and moral condemnation to heavily
polluting enterprises. In addition to reducing the debt
financing of heavily polluting enterprises, public
opinion will also affect the investment and financing
behavior and enterprise strategy of enterprises
through supervision mechanism and reputation
mechanism (Zhu, Tan, 2020). On the one hand,
public opinion pressure forces heavily polluting
enterprises to strengthen environmental governance,
improve the level of environmental information
disclosure and reduce inefficient investment (Zhan,
2021). In this case, the corporate strategy may tend to
be conservative , making the corporate change
from prospectors to defenders. On the other hand, the
social reputation mechanism will promote enterprises
to establish a corporate image in line with the concept
of green development. Heavily polluting enterprises
may increase green investment, seek strategic
transformation and adopt more radical strategies to
change from defender to prospectors.
Based on the above analysis, this paper puts
forward the following assumptions:
Hypothesis H1a: Green credit policy will turn
heavy polluting enterprises from prospectors to
defenders.
Hypothesis H1b: Green credit policy will turn
heavy polluting enterprises from defender to
prospectors.
2.2 Intermediary Effect of Financing
Constraints
Firstly, the green credit policy has reduced the total
amount of funds and financing channels of heavily
polluting enterprises to a certain extent, making
enterprises face more severe financing constraints.
From the perspective of banking financial
institutions, under the strict green financial measures,
commercial banks are bound to strictly control the
credit gateway of heavily polluting enterprises and
improve their loan threshold. Banks use credit
supervision means to strictly control the credit
approval process for enterprises with high energy
consumption and high pollution, Raise the financing
threshold and cost of enterprises (allet, 2015; Zhu,
Tan, 2020). From the perspective of the whole capital
market, green credit guides social funds from the
polluting field to the green field. Under this policy
guidance, the willingness of external creditors to
provide debt capital for heavily polluting enterprises
is weakened (Wu, et al., 2012), investors will reduce
their investment in polluting enterprises, so the debt
financing level of heavily polluting enterprises will
decline. Secondly, the aggravation of the financing
constraint level of enterprises will change the
strategic choice of enterprises. Specifically, there are
two possible changes. On the one hand, after the
implementation of the green credit policy, heavily
polluting enterprises facing financing constraints lack
