economic impact of information system reform is
quite large, which reduced the non-performing loan
ratio of banks by nearly 40% (Saibal Ghosh, 2019).
Therefore, bank regulators can consider establishing
a credit investigation system as a macro-prudential
supervision over the growth of non-performing loans
(Wahyoe, et al., 2017).
To sum up, information asymmetry can lead to
adverse selection, moral hazard and credit mismatch
in the credit market. By establishing a credit
investigation system to share credit information,
banks can enhance their ability to select investors
from different risk categories, reduce adverse
selection of borrowers and promote the increase of
credit scale. At the same time, the reputation
constraint mechanism can improve the default cost,
reduce credit risk, and solve the financing difficulties
of small and micro enterprises.
3 MODEL SETTING
3.1 Research Hypothesis
If a social credit system, including the credit
investigation system, has established a shared credit
information collection, and with the continuous
improvement of this system, the availability of
corporate credit information and even more
characteristic information continues to increase, then
adverse selection The problem will be alleviated.
With a relatively complete social credit system, it is
easier for venture investors to screen start-ups and
make investment decisions. This means that the
improvement of the social credit system also means
that the default cost of start-ups will increase, and the
problem of moral hazard will also be alleviated.
Therefore, this article makes the following
assumptions:
H1: The higher the degree of Changsha’s social
credit system, the larger the scale of venture capital.
3.2 Sample Selection and Data Sources
Considering the representativeness of the sample
cities’ regional geographic location and venture
capital scale, as well as the availability and
completeness of data, this article chooses Changsha
as the analysis object. All the investment events of all
venture capital institutions in the sample cities from
2010 to 2019, the per capita GDP data of the sample
cities from 2010 to 2019, and the proportion of the
output value of the secondary and tertiary industries
in GDP are all taken from the wind database. The City
Business Credit Environment Index (CEI) is mainly
taken from the “CEI Blue Book”. For years with
missing data, the mean value of two consecutive
years is used as an interpolation substitute. In
particular, due to the lack of data in 2014, data of
2013 is the average of previous years, and the 2014’s
is the average of 2013 and 2015.
3.3 Variable Definition and Model
Setting
According to the research purpose and related
literature, this paper chooses the ratio of venture
capital investment to the national total venture capital
investment to measure the scale of entrepreneurship.
This article chooses city’s commercial credit
index as the measure of the level of social credit
system construction. The Urban Commercial Credit
Index is jointly compiled by the Integrity Research
Center of the Chinese Academy of Management
Science and other institutions. It is based on the
theory of social credit system, urban credit system,
and enterprise credit management theory. It provides
financial credit instruments, commercial credit sales,
and enterprise comprehensive evaluation of factors.
Finally get the social credit score of each city and
rank it. The social credit score ranges from 1 to 100.
The higher the score, the higher the construction level
of the city’s social credit system. Existing research
results show that CEI is a reliable indicator to
measure the degree of perfection of the city’s credit
system and the results of its operation. Considering
that the changes in the social credit system may not
have an immediate impact on the decision-making of
venture investors, this article chooses the first-order
lag and second-order lag of CEI as explanatory
variables.
The model established in this paper is as follows:
112 23

Where,
y

is the explained variable, which
measures the scale of venture capital investment.

are explanatory variables, which
measures the degree of perfection of a city's social
credit system.
t

is control variable. We
choose GDP per capita (ten thousand yuan), the
proportion of secondary industry output
value in GDP,
and the proportion of tertiary industry output value in
GDP to exclude the influence of local economic
development level and industrial structure on venture
capital scale.
All of variable names, symbols and definitions in
