probability closely matches the observed cumulative
probability. Therefore, it follows the normal
distribution. It can be found in Figure 2 that the
standardized residual scatter points are distributed
around the 0 value, roughly within a band-shaped
area, and there is no obvious trend. This means that
the variances of the random errors are homogeneous,
there is no heteroscedasticity problem, and the fit is
good.
4 CONCLUSION
This article obtains a series of research results
through statistical data analysis of Anhui Province’s
GDP and five impact indicators. After conducting
descriptive statistics on the data, it was found through
correlation analysis that there is strong correlation
and collinearity between the indicators. In order to
eliminate the impact of collinearity on the results, the
five indicators were dimensionally reduced through
factor analysis and finally two common factors were
obtained. These two public factors are named social
financial factors and social construction factors
respectively. Finally, by establishing a multiple linear
regression model, the binary linear regression
equation of standardized GDP with respect to the
above two factors was obtained. After testing, it can
be proved that the equation has a good fitting degree.
It can be seen from the obtained regression
equation that Anhui Province's GDP has a certain
positive linear correlation with social
macroeconomics, such as consumption, trade, and
social infrastructure, such as school and highway
construction. Therefore, in order to implement
economic construction as the center and promote
high-quality economic development in Anhui
Province, the following guiding opinions are put
forward for reference.
Deepen opening to the outside world and expand
foreign trade cooperation: Promote the in-depth
integration of Anhui Province with the international
market and strengthen economic and trade
cooperation with countries along the Belt and Road.
It is recommended to formulate more flexible trade
policies, attract foreign investment and technology
introduction, and improve the level of opening up to
the outside world. At the same time, we will
strengthen the development of cross-border e-
commerce and digital economy and improve the
efficiency of import and export.
Stimulate residents’ consumption vitality:
Stimulate residents' consumption by increasing
residents' income levels and improving employment
rates. Encourage the development of cultural tourism,
health care and other consumer fields, and cultivate
new consumption growth points. In addition, promote
consumer confidence, strengthen brand building, and
improve product and service quality.
Increase public budget investment: Increase
government financial investment, especially in the
fields of education, medical care, science and
technology and other social undertakings. Increase
support for innovative enterprises and scientific
research institutions to promote technological
innovation and industrial upgrading. At the same
time, the fiscal expenditure structure should be
optimized to ensure the effectiveness and
sustainability of capital investment.
Accelerate the construction of transportation
infrastructure and improve the connectivity of the
province: Improve infrastructure levels and shorten
transportation time between urban and rural areas and
between provinces. Accelerate the planning and
construction of transportation infrastructure such as
highways and railways, promote smooth logistics,
and promote coordinated development of industries.
This will help reduce logistics costs, improve
production efficiency, and enhance Anhui Province’s
competitiveness in the global value chain.
Optimize the education system and promote talent
cultivation: Increase investment in higher education
and improve the overall level of educational
resources. At the same time, enterprises are
encouraged to cooperate with universities to
strengthen the integration of industry, education,
research and application, and improve the practicality
and employment rate of higher education. Cultivate
more high-quality talents, provide intellectual support
for upgrading the economic structure, and build an
innovation highland.
