直接融資的經濟增長效應研究
發(fā)布時間：2018-07-24 17:30
【摘要】：隨著我國經濟體制改革的逐步深入和資本市場的快速發(fā)展,我國直接融資也獲得了相應的發(fā)展,但是與間接融資相比,我國直接融資在融資結構中所占的比重仍然嚴重偏低,尤其是與發(fā)達國家和新興資本市場國家直接融資的發(fā)展情況相比,我國直接融資還存在著巨大的差距。與此同時,我國經濟經過多年的高速發(fā)展,已經達到了一個較高的水平,為了保證經濟的持續(xù)穩(wěn)定增長,金融體系的深化改革是必不可少的。故本文試圖通過對直接融資的經濟增長效應進行系統(tǒng)的分析,從而為我國金融體系的改革發(fā)展提供些許理論支持,以實現經濟的持續(xù)穩(wěn)定增長。 首先本文對直接融資影響經濟增長的作用機制進行了探析。在對直接融資的經濟功能進行總結的基礎上,結合內生增長理論,初步探析了直接融資促進經濟增長的作用渠道——資本積累和技術進步。緊接著,通過對普通的內生增長模型進行改進,用理論模型證明了直接融資能夠通過資本積累渠道促進經濟增長。同時,構建了一個引入“提供直接融資服務的金融部門”的技術創(chuàng)新內生增長模型,通過對穩(wěn)態(tài)經濟增長率的求解,證明了直接融資能夠通過技術進步渠道促進穩(wěn)態(tài)經濟增長率的提升。 由于直接融資和間接融資具有相似的經濟功能,他們影響經濟增長的作用機制也比較一致。所以僅僅從作用機制方面來研究直接融資的經濟增長效應,顯然還不夠深入和徹底。 故本文基于直接融資與間接融資比較的角度,探析了直接融資相對于間接融資對經濟增長所具有的優(yōu)勢和劣勢。首先,我們從直接融資和間接融資所需耗費的社會資源不同出發(fā),對金融內生增長模型進行改進,通過對均衡狀態(tài)進行分析,得知：直接融資相對于間接融資對長期經濟增長具有一定的優(yōu)勢,提高直接融資在融資結構中的占比,可以減少金融部門對社會資源的消耗,增加生產資本的總量,最終提升穩(wěn)態(tài)經濟增長率。 更進一步,為了使理論研究與現實更加接近,我們從信息不對稱的角度探析了直接融資相對于間接融資對經濟增長所具有的優(yōu)勢和劣勢。通過構建了一個基于信息不對稱的“競爭性經濟系統(tǒng)”的簡單模型,并對不同信息條件下均衡狀態(tài)的分析,得知：直接融資的發(fā)展會因減少了全社會代理成本的支出而使得全社會的凈產出獲得增長,當直接融資的發(fā)展相對落后時,適當的發(fā)展直接融資,提高直接融資在融資結構中的占比,有利于經濟的增長。 緊接著,對我國直接融資的發(fā)展狀況進行了分析,并以此為基礎使用我國的相關經濟數據,運用多種實證方法對本文的理論分析結論進行實證分析。 對于直接融資通過資本積累渠道促進經濟增長的理論觀點的檢驗,本文首先對影響我國經濟增長的因素進行了實證分析,然后再對直接融資與資本積累的關系進行實證檢驗。檢驗結果表明：直接融資通過資本積累渠道促進經濟增長,這樣一種傳導機制在我國是存在的。 對于直接融資通過技術進步渠道促進經濟增長的理論觀點的檢驗,我們先借鑒先前學者的統(tǒng)計方法,測算出我國1981-2010年間的技術進步率,并對技術進步對經濟增長貢獻份額的分析,然后再對直接融資與技術進步率之間的關系進行實證檢驗。檢驗結果表明：21世紀以來,“直接融資通過技術進步渠道促進經濟增長”的作用機制已經在我國初步有效運行。 關于直接融資相對于間接融資對經濟增長具有一定優(yōu)勢的理論觀點的檢驗,我們使用我國1986—2010年間的相關數據,對我國融資結構變化和經濟增長率之間的關系進行了實證檢驗。實證檢驗結果表明：現階段我國適度提高直接融資在融資總額中的比重將有助于經濟增長率的提升。 最后,依據本文的研究成果對我國直接融資的發(fā)展提出了若干政策建議。 總之,本文通過對直接融資的經濟增長效應進行初步的系統(tǒng)研究表明,現階段發(fā)展直接融資,擴大直接融資在我國融資結構中的比重,對我國的經濟增長是大有裨益的。
[Abstract]:With the gradual deepening of the reform of our economic system and the rapid development of the capital market, the direct financing of our country has also obtained the corresponding development, but compared with the indirect financing, the proportion of direct financing in the financing structure of our country is still seriously low, especially the development of direct financing with the developed countries and the countries of the emerging capital market. In contrast, China's direct financing still has a huge gap. At the same time, China's economy has reached a high level after many years of rapid development. In order to ensure sustained and stable economic growth, the deepening of the reform of the financial system is essential. Therefore, this paper tries to make a systematic Study on the economic growth effect of direct financing. The analysis will provide some theoretical support for the reform and development of China's financial system so as to achieve sustained and stable economic growth.
First of all, this paper analyses the effect mechanism of direct financing on economic growth. On the basis of summarizing the economic function of direct financing and combining the endogenous growth theory, this paper preliminarily analyses the role channel of direct financing to promote economic growth - capital accumulation and technology step. Through the theoretical model, it proves that direct financing can promote economic growth through the capital accumulation channel. At the same time, a new endogenous growth model which introduces the "financial sector providing direct financing services" is constructed. Through the solution of the steady state economic growth rate, it is proved that direct financing can be promoted through the technological progress channel. The increase in the growth rate of steady state economy.
Since direct financing and indirect financing have similar economic functions, the mechanism of their impact on economic growth is also consistent. Therefore, it is obviously not enough and thorough to study the economic growth effect of direct financing only from the mechanism of action.
Therefore, based on the comparison of direct financing and indirect financing, this paper analyzes the advantages and disadvantages of direct financing relative to indirect financing. Firstly, we improve the endogenous growth model from the different social resources that the direct financing and indirect financing need to consume, and analyze the equilibrium state. We know that direct financing has a certain advantage over the long-term economic growth compared with the indirect financing, and increases the proportion of direct financing in the financing structure. It can reduce the consumption of the financial sector to the social resources, increase the total amount of production capital, and ultimately improve the steady state economic growth rate.
Further, in order to make the theoretical research closer to the reality, we analyze the advantages and disadvantages of direct financing relative to indirect financing from the perspective of information asymmetry. A simple model of "competitive economic system" based on information asymmetry is constructed and balanced under different information conditions. The development of direct financing will increase the net output of the whole society by reducing the cost of the whole society. When the development of direct financing is relatively backward, direct financing is properly developed, and the proportion of direct financing in the financing structure is improved, which is beneficial to the economic growth.
Then, it analyzes the development of direct financing in China, and uses the relevant economic data of our country on this basis, and uses a variety of empirical methods to make an empirical analysis of the theoretical analysis conclusions of this paper.
For the theoretical analysis of direct financing through capital accumulation channels to promote economic growth, this paper first empirically analyses the factors that affect China's economic growth, and then empirically tests the relationship between direct financing and capital accumulation. The results show that direct financing promotes economic growth through capital accumulation channels. Such a transmission mechanism exists in our country.
For the theory of direct financing through the technical progress channel to promote economic growth, we use previous scholars' statistical methods to calculate the rate of technological progress in China in the past 1981-2010 years, and analyze the contribution of technological progress to economic growth, and then the relationship between direct financing and the rate of technological progress is carried out. The test results show that since twenty-first Century, the mechanism of "direct financing through technological progress channels to promote economic growth" has been in a preliminary and effective operation in China.
On the theoretical point of view that direct financing has a certain advantage over indirect financing for economic growth, we use relevant data from 1986 to 2010 in China to test the relationship between the change of financing structure and the economic growth rate in China. The results of empirical test show that China is moderately raising direct financing at the present stage. The proportion of total financing will help increase the rate of economic growth.
Finally, based on the research results, we put forward some policy recommendations for the development of direct financing in China.
In a word, through a preliminary and systematic study of the economic growth effect of direct financing, this paper shows that developing direct financing at the present stage and expanding the proportion of direct financing in China's financing structure are of great benefit to the economic growth of our country.
