Since the reform and opening up, China’s economic level has witnessed rapid growth, while the financial industry is gradually growing. This paper mainly explore the relationship between the development of China’s financial industry and the economic situation. To measure the economic growth by GDP; to measure the development of domestic financial industry by financial development indicators such as currency and quasi-currency, gold reserve, foreign exchange reserve, the number of domestic listed companies (A, B shares), total stock issuance capital, total stock market value, stock turnover, etc. Using the relevant data from 1992 to 2017, this paper explores the relationship between the two by means of multiple regression model and principal component analysis. The research shows that with the increase of money supply and the number of listed companies, as well as the expansion of the total size of the stock market, China’s economic development has improved significantly and accordingly put forward relevant suggestions.

Over the past 40 years of reform and opening up, China’s economy has undergone tremendous changes and made tremendous achievements. At the same time, the financial industry has undergone tremendous changes, especially China’s economy has shown miraculous double-digit growth and finance has also made breakthrough development after China’s accession to the World Trade Organization (WTO). The development of financial industry has also made China’s economy develop rapidly, but, it has brought a variety of drawbacks. After the international financial crisis in particular, the world’s major economies have realized that the real economy is the important basis for the survival of human society and began to pay attention to strengthening support for the development of the real economy. Simultaneously, as China’s current financial system is becoming larger and larger, the financial industry is dominated by traditional indirect financing, the proportion of direct financing is low and the financial efficiency still needs to be improved.

At present, China is in the period of economic restructuring under the new normal. It is very important to deepen the reform of financial system and enhance the function of financial industry serving the real economy. As a newly industrialized country, they should pay more attention to the development of real economy. The development of real economy plays a key role in China’s economic stability, social stability and the realization of the goal of building a well-off society in an all-round way. Therefore, the development of real economy is the primary goal of economic development in the world, especially in China and also the necessary condition for healthy economic development. Through the analysis of domestic economic development, this paper will further introduce financial industry development indicators and explore the relationship between financial industry development and economic progress, with a view to promoting the further development of China’s economy.

From the beginning to today, financial industry has formed a mature financial environment and market, producing complete financial products. Financial industry or financial products play an increasingly important role in China’s economic development and their impact is also growing. At the same time, with the development of society and the enrichment of economic growth theory, scholars have explored the role of financial development in economic growth.

Since Levine (1993) [

China and makes an empirical analysis on the relationship between the average growth rate of per capita GDP and the average growth rate of financial assets in stock market and banks. Han Yanchun (2003) [

The above studies have adopted many indicators related to the development of the financial industry, from a more detailed and reasonable point of view to define the development of the financial industry. These literature can be roughly summarized as follows: First, economic growth cannot be separated from the support of funds; Second, the sound development of financial industry can provide financial support for economic growth and improve utilization efficiency; Third, the relationship between financial development and economic growth is a two-way constraint and complementary.

In the past ten years, the proportion of financial industry in China has continuously exceeded that of most developed economies. Compared with the developed and developing countries which are in the same stage of economic development in history, China’s financial industry accounts for a relatively high proportion at this stage. Therefore, when studying the impact of the development of China’s financial industry on economic growth, we should take full account of China’s national conditions and select more appropriate indicators in the model.

This paper will measure economic growth by gross domestic product y. The development of domestic financial industry will be measured by monetary and quasi-currency x 1 , gold reserve x 2 , foreign exchange reserve x 3 , the number of domestic listed companies (A, B shares) x 4 , total stock issuance capital x 5 , total stock market value x 6 , stock turnover x 7 .

Establish the following models:

y = β 0 + β 1 x 1 + β 2 x 2 + β 3 x 3 + β 4 x 4 + β 5 x 5 + β 6 x 6 + β 7 x 7 + u . (1)

We use the annual data of the relevant indicators from 1992 to 2017 to analyze the contribution rate of the above seven financial development indicators to China’s economic growth and the significant degree of their impact.

This paper studies the problems in the field of economy and finance. At this time, most of the time series observations are not generated by stationary processes. Therefore, first of all, we need to test the stationarity. Using ADF unit root test, we can see that all variables are second-order monolithic and there will be no pseudo-regression.

The stationarity test shows that all variables are second-order monolithic, which satisfies the precondition of Granger causality test. After Granger causality test, we know that there is Granger causality between dependent GDP and independent currency and quasi-currency, gold reserve, the number of Listed Companies in China, foreign exchange reserve, total issuance capital, total stock market value and stock turnover. Among them, except the one-way causal relationship between the total issuance of shares and GDP, the other variables and GDP are causal each other.

After multiple linear regression of the above data, the following results are obtained:

y = 36072.76 + 0.354 x 1 − 10.671 x 2 + 1.242 x 3 + 25.342 x 4 + 2.369 x 5 − 0.0005 x 6 − 0.013 x 7 .

t = (19.279) (−2.757) (2.404) (3.669) (2.744) (−0.016) (0.012)

R 2 = 0.999, R ¯ 2 = 0.999, F = 5511.686, DW = 1.89.

From the above multiple regression models, it can be seen that the goodness of fit R 2 is very close to 1, the fitting degree of the model is good, and the explanatory ability of the explanatory variables is strong; Then, F = 5511.686, the integrity of the regression model is significant and the model construction is reasonable x 6 and x 7 failed to pass the t test and the variables x 2 and x 6 were negatively correlated with GDP, so the economic significance expression was unreasonable, so they failed to pass the test in the economic sense. The above problems show that there are serious multi-collinearity in the multivariate linear regression model, which needs to be revised. Therefore, the principal component analysis method is used to further modify the regression model and get the principal component regression model.

The KMO test value of the samples processed by SPSS is 0.788, more than 0.5. The significant P value (Sig) of Bartlett spherical test results in each year is 0.0050 and the chi-square distribution value is large, which is suitable for principal component analysis.

According to the results of

According to the results of

F 1 = 0.41 Z x 1 + 0.396 Z x 2 + 0. 395 Z x 3 + 0. 398 Z x 4 + 0. 412 Z x 5 + 0.397 Z x 6 − 0.179 Z x 7 .

F 2 = 0.091 Z x 1 + 0.153 Z x 2 − 0.096 Z x 3 + 0.207 Z x 4 − 0.014 Z x 5 + 0.086 Z x 6 + 0.953 Z x 7 .

According to the principal component expression, the standardized explanatory variables of each year are brought in and the principal component scores of each year are calculated. According to the annual score of principal component and the standardized y, the principal component regression model is obtained:

Y = 0.413 F 1 + 0.059 F 2 .

t = (51.299) (2.884)

R 2 = 0.99, DW = 1.55.

From the results, the goodness-of-fit of regression model is 0.99 and the t-test values of F 1 and F 2 are significant. Moreover, using DW = 1.55 to test the autocorrelation of the model, we can conclude that the model does not have autocorrelation. Using White test to test the heteroscedasticity of the model, the results show that the model does not have heteroscedasticity, which also shows that the selection of principal components is reasonable.

Two principal component expressions are substituted into the principal component regression model, and the normalized regression model is obtained:

Y = 0.175 Z x 1 + 0.173 Z x 2 + 0.158 Z x 3 + 0.177 Z x 4 + 0.17 Z x 5 + 0.169 Z x 6 + 0.018 Z x 7 .

The final regression model has reasonable economic significance, Variable t-test is passed, multiple collinearity between variables is basically eliminated and the regression model established by principal component method is reasonable.

According to the above regression model, when other factors remain unchanged, the gross domestic product will increase by 0.175, 0.173, 0.158, 0.177, 0.17, 0.169 and 0.018 units for each unit increase in currency and quasi-currency, gold reserve, foreign exchange reserve, the number of domestic listed companies (A and B shares), total issuance of shares, total market value of stocks and volume of stock transactions. The coefficient value of domestic listed companies (A, B shares) has the greatest impact on GDP. With the increase of the number of domestic listed companies, the company’s earnings also increase and its contribution to GDP is also growing. In addition, money, quasi-currency and gold reserve contribute a lot to GDP.As a circulation tool, money is an indispensable element of national economic growth. The increase of money, quasi-money supply and gold reserve plays an important role in stimulating the increase of GDP. The total stock price is also an important factor affecting GDP. With the increase of the total stock price, the gross domestic product also increases. Of course, with the increase of the total stock price, the stock derivative securities and option prices in the financial market also contribute to the increase of the gross domestic product.

Based on the above results, the conclusions are as follows:

1) Economic growth is inseparable from the growth of money supply.

2) The number of listed companies has a significant impact on improving a country’s economic level.

3) Stock and its derivatives markets have a great impact on the economic environment.

1) Encouraging Financial Institutions to Participate in Economic Construction.

The government should encourage financial institutions to take an active part in economic construction by evaluating or establishing a sound regulatory mechanism; make use of financial institutions to collect idle funds; give full play to the advantages of financial institutions in collecting funds; concentrate funds on the market; solve the demand for funds for market development and promote economic development [

2) Promoting Domestic Economic Development with the Development of Financial Industry.

The development of financial industry can improve the scale and technology level of material capital accumulation, thereby improving the level of material capital accumulation [

3) Strengthen the Supervision and Restriction of Finance.

In recent years, China’s financial industry has developed rapidly and a large number of funds have poured into the financial market. The government must strengthen the control of fictitious economy to ensure the healthy and stable development of economy [
