The Shanghai Composite Index hit 4,000 Wednesday, as other major indexes climbed to new highs. Generally speaking, the bull market of 2015 is beneficial for economic development, according to Xu Hongcai, head of the department of information at the China Center for International Economic Exchanges.

Although it has been predicted that China's GDP will come in under 7 percent in the first quarter, the stock market continues to thrive.

Many new investors have entered the market since March. Experts said that the pressure of economic restructuring can be relieved by the stock market.

The economy is more different than it was the last time the index reached 4,000 in 2007.

Economic growth has slowed, yet investors remain confident, believing the recently implemented reforms will drive share prices higher.

Xu said that there are many hot spots in the stock market now, such as the "One Belt, One Road" project, State-owned enterprises' reform, rapid development of the services sector and the Free Trade Agreement.

At the same time, many people are also concerned about the future trend in stocks, as in whether they will rise or fall.

Industry analysts believe there is bound to be a correction in a strong market, so they have warned investors to prepare themselves.
