What is investment banking? According to the CEO of Morgan Stanley, Gaemon, accepted definition of what the investment banking at present is that: Investment bank is an important financial intermediary in capital market and the main function of which is to provide financial services for capital demanders and capital suppliers  . Investment banking can be roughly divided into two parts that for the primary market that is the issuance and underwriting of securities and for the secondary market that is the broken dealer operations after the issuance.
Investment banking and commercial banks are inextricably linked in the modern market economy  . Firstly, the relationship between the capital market that targeted by investment banks and the currency market that targeted by commercial banks is tight and secondly investment banks and commercial banks are all intermediaries in the financial market, but investment banks are just intermediaries for investors and fundraisers in the capital market, while commercial banks are for depositors and accommodators in the currency market. Besides, we should also note that different parties will have different rights and obligation in investment banking and commercial banking business. The investment banking department of each securities traders is a link between investors and financiers in the investment banking business and earns commissions, so it will generate rights and obligations directly between investors and financiers. On the contrary, commercial banks play an intermediary role in the indirect market which mainly serves between depositors and accommodators, so commercial banks are both the supplier and the demander of funds and finally there is no direct relationship of rights and obligations between depositors and accommodators  .
The investment banking can be traced back to the 1980s and there were many trusts and investment companies appeared, which have played the role of investment banks in some ways and began to undertake most of the investment banking business though they are not proper investment banks. In the mid-to-late 1980s, China had established a large number of securities companies which started late, but developed rapidly, though there are still some problems such as the relatively smaller capital, the relatively lower specialization degree and inadequate innovation and other problems  . The State Council issued the Decision of the State Council on Reform of the Financial System in 1993, which clarifies the principle, the divided operation and management that implemented by Chinese trust companies, insurance companies, securities companies and commercial banks to control financial risks within the acceptable range. The Law of the People’s Republic of China on Commercial Banks establishes the principle of separate banking operation in the form of law, which passed in 1995. This series of reforms are not properly separated operation or mixed operation in developed countries, but only a transitional stage. Now, the investment banking in our country has shown signs of transforming into the mainstream model of international banks that transformed from the traditional business of deposit and loan and settlement as the main to the new business of intermediary services. Although we have made satisfactory progress and achievements, there are still some problems such as lack of experience, unitary service and lack of innovation compared with international investment banking  .
The investment banking of commercial banks in China can be traced back to 2002 that the Investment Banking Department was first established by the Industrial and Commercial Bank of China, which is the earliest and largest investment banking department of commercial banks with most complete and perfect service in China, and has formed a significant brand effect  .

Therefore, the practitioners of investment banking of commercial banks need to be very familiar with the latest national policies and economic situation.
2) The Industry Regulation Risks
The main legal basis for the operation of Chinese investment banking is the Securities Law. Therefore, the practitioners investment banking of commercial banks must effectively avoid the possible legal risks.
3) The External Market Risks
A variety of economic factors will have a numerous effect on investment banking, such as interest rate fluctuation risk, stock price fluctuation risk, exchange rate fluctuation risk, commodity trading risk and basic risk and etc. The practitioners of investment banking should closely monitor these macro and micro economic factors and minimize the possible adverse impact on investment banking.

6. Problems in Current Investment Banking of Chinese Commercial Banks
1) The Rigid Structure
Although the investment banking of Chinese commercial banks has made great progress and achievements, the main business is still to take deposits and make loans to earn interest margins. In order to make the investment banking business get more attention and achieve great development in commercial banks, it is necessary to change the business system of Chinese commercial banks essentially, especially in changing the dominant situation that taking deposits and making loans.
2) Inadequate Capability in Business Management
The supporting rules and regulations of investment banking, a new business in Chinese commercial banking systems, are still in the early construction stage，which should be the same with the securities companies’ that establish a complete system covering contracting，undertaking and underwriting and promote the business standards of relevant practitioners.
3) The Serious Phenomenon of Part-time Jobs
The headquarters of major commercial banks have special investment banking departments and relevant persons in charge, but it is limited in the branches. According to the previous survey report that many customer managers are part-time investment banking management in branches  . In order to achieve the scale development of investment banking in commercial banks, it is necessary for each branch to have a president and a section chief in investment banking to avoid the part-time phenomenon as far as possible.
4) Insufficient Response Management of Investment Banking
The risk of investment banking is special and complex that the disposal procedures are relatively more, besides the necessary legal proceedings, the disposal of collateral should also be carried out and if the result is so serious that may also lead to the reputation risk.
5) Imperfect Internal Mechanism
The current risk control measures of Chinese commercial banks are not perfect and even can not cover the needs of their corresponding products at all. As everyone knows that the development and implementation of investment banking need to pass a strict approval process, otherwise it will cause serious risks out of control. Therefore, it is necessary to establish a sound internal control system and strengthen the power and responsibility system.

Chinese investment banking incentive mechanism, whether it is in the investment banking department of securities companies or the investment banking department of commercial banks, are not fully execute in accordance with the international general investment banking incentive mechanism  . If the staff reward and punishment mechanism is not perfect, it is difficult to motivate employees and achieve the sound development of performance.

Since the second half of 2014, the global economic situation has gradually declined and investment banking business has been greatly impacted that the growth of Chinese economic situation is not obvious. Although China has launched a 4 trillion yuan stimulus plan, the negative effects of its sequelae are becoming more and more obvious and the adverse effects of these macroeconomic factors will have a great shock on the investment banking of commercial banks  .
7. Suggestions for Commercial Banks to Develop Investment Business
1) Changing the business thinking of commercial banks and the existing business structure of “Taking Deposits and Make Loans”. Then with the maturity of Chinese capital market, a number of commercial banks continue to upgrade and transform their industries and the simply taking deposits and making loans can not only be helpful with the new profit growth points for enterprises, but also increase the operational risk of commercial banks. Therefore, it is necessary to change the dominant business situation of “taking deposits and making loans”.
2) Establishing a sound risk transmission and isolation mechanism. The “firewall” system must exist widely in every aspect of investment banking. The most important link in the “firewall” system is the examination and approval of a reasonable system and investment desperation system, and the bank must do a good job of monitoring the rights.
3) Establishing and improving the internal control system. The financial advisory business and equity financing business account for a considerable proportion among the existing investment banking of Chinese commercial banks  . It is necessary for the two core investment banking businesses to establish sound internal control measures to reduce operational risks to a controllable range.
4) It is necessary to improve the professionalism and ethics of relevant practitioners and practitioners of investment banks should constantly learn new laws and regulations and the development experience of foreign and domestic counterparts and constantly improve their own professional skills.
5) The laws and regulations on the investment banking of commercial banks should be perfect  . The main legal basis of investment banking of Chinese commercial banks at present is the Securities Law, but lacks of guidance documents for specific businesses. Therefore, it is necessary to implement legal documents to various departments and even to various types of business to improve the loopholes of the law regulations.
6) It is necessary to strengthen the innovation of business types and product types. In terms of market innovation, we should not only keep the traditional PPP business, but also pay attention to the investment business Pre-IPO and PE. In terms of customer innovation, we should attach importance to government customers and listed and proposed listing customers. In terms of product innovation, banks can expand actively managing fund business and combined fund management business. In terms of business model innovation, it is necessary to link up with the asset management business in the industry.
