future cash inflow (Yu Minggui et al.). In this paper,
the volatility of enterprise profit is used as the
measurement index of enterprise risk taking. First, it
is necessary to adjust the annual ROA (profit before
interest and tax/total assets at the end of the year) of
each company with the average value of all listed
companies in the whole industry. To be specific, the
ROA of each company is subtracted from the average
value of the industry, and the difference is named
ROA_ADJ. Then, three years is taken as an
observation period. The standard deviation of ROA of
each listed company after industry adjustment during
the observation period was calculated to measure the
Risk level of the enterprise. Formula is:

2. Explanatory variable: political correlation gap
(PCD).
In the previous studies on political correlation, the
measurement index mainly takes two forms: dummy
variable method and assignment method.
Because this article needs to be calculated,
chairman and CEO of specific political correlation
distance, so first assignment method is used to define
the chairman and CEO of political association,
concrete is divided into 6: served as the central unit 5,
the provincial units of 4, municipal units 3, county,
district units to 2, the villages and towns and the
following is 1, no political association of 0.
In the case of the same person serving in more
than one institution, the highest institution was taken
to calculate the difference between the two, and the
absolute value was taken as the specific political
correlation distance.
In addition, the non-zero values are all one, and
zero is not changed, as a measure of whether there is
a political correlation gap.
3. Control variables
Referring to a large number of previous studies on
enterprise risk taking, this paper sets the following
control variables: Roa (profit before interest and tax);
SIZE equals the natural logarithm of the company's
total assets at the end of the period. LEV, capital
structure, is equal to the ratio of ending total liabilities
to ending total assets; AGE is the number of years a
company has been listed, which is equal to the natural
log of the number of years a company has been listed
plus one. Ownership means that Ownership is equal
to the shareholding ratio of the largest shareholder at
the end of the year; Growth refers to the Growth of
the enterprise, which is equal to the annual Growth
rate of the enterprise's operating revenue.
In order to verify the hypothesis in this paper, the
following model is set according to Yu Minggui et al.
(2013):
πΉπππ= π·

4 EMPIRICAL RESULTS AND
ANALYSIS
(1) Descriptive analysis
According to the final data results, in China's
listed manufacturing industry, the proportion of
companies with political association distance
between CEO and chairman is 46.23%, which
indicates that more than half of the companies have
the same level of political association between
chairman and CEO. The maximum value of
enterprise risk taking is 0.44, and the minimum value
is 0.0005. It can be seen that different manufacturing
companies have relatively large differences in risk
taking. From the perspective of ownership structure,
the average shareholding ratio of the first shareholder
is 0.31, which shows that the equity of listed
manufacturing companies in China is still highly
concentrated. From the perspective of company size,
the maximum value of the processed data on the total
assets of the company is 25.47 and the minimum
value is 20.01. It can be seen that there is an obvious
gap in the size of the design sample companies in this
research. In terms of the company's capital structure,
the maximum value is 0.838, and the minimum value
is 0.009. It can be seen that the asset-liability ratio of
listed manufacturing companies in China has a
significant difference, and its average value is 0.34,
which is very similar to previous research literature
(Yu Minggui et al., 2013) and is at a The table shows
the regression analysis of political relationship
distance and enterprise risk taking.
(2) Distance between enterprise risk taking and
political association
After adding all control variables and annual
dummy variables, the regression coefficient is -
0.0062, and is significantly negative at 5% level,
indicating that the political correlation gap between
CEO and chairman can significantly reduce the level
of risk-taking of enterprises, that is, companies are
more prone to give up those projects with high return
and high risk when facing investment decisions.
Hypothesis H1 is supported.
To political level correlation distance and the
enterprise risk for regression, test results show that in
the control variables and the annual virtual variables,
regression coefficient is 0.0022, and a significant at
1% level is negative, it further proves the hypothesis
H1, ask clear political relevance gap, the greater the
inhibition of risk bearing level of the enterprise, the .
