"Three rate" refers to the monetary policy interest rate, exchange rate and deposit reserve ratio. Because our country is in a special historical period of market economy stage, interest rate and exchange rate market-oriented reform is seriously lagging behind in overall economic development, and the market-oriented reforms in the financial sector is the most important country in economic reform must be careful but should actively promote links, because of the unreasonable allocation of financial resources will lead to the most serious misallocation of resources and economic development inefficiencies. Therefore, under the current complex domestic and international economic environment, China's "three rate" trend, global attention, especially in the exchange rate, or test the political wisdom of the difficult international game. RRR and three nonslip outdoor ramp floor economic variables raised the deposit reserve rate is mainly dependent on three economic variables, namely the current period foreign exchange newly added passive delivery amount, the amount of money due the open market and economic growth. From the new delivery point of view, although in March this year, China is seeing a trade deficit of $ 7.24 billion, but foreign exchange may also continue to increase, mainly because of trade settlement and customs declaration date is not synchronized. Moreover, a slight deficit a month and does not indicate a trend of change, as the world economic recovery and China's export growth is expected in the next month there will be more than ten billion US dollars of trade surplus, foreign exchange accounted attendant money growth, the central bank will increase liquidity pressure recovery. Therefore, we expect the central bank will continue to use open market operations and raising the deposit reserve ratio to recover mobility. Then from the point of view of economic growth is expected in the first quarter GDP grew more than 12%; the rapid rise in the first quarter of this year despite the GDP in the first quarter last year, largely due to lower GDP growth base and long-term effect of policies to stimulate domestic demand led, the next three quarters GDP is likely to decline gradually small margin, but the growth rate of 12% should indeed arouse the laminated wood plastic board Portugal attention of the government administration; moreover, the main driving force of economic growth comes from investment in fixed assets, and the most effective way to reduce the investment is By raising the reserve ratio of commercial banks to reduce loans available for investment projects. Practice also shows that China's economy, a higher-than-expected GDP growth is often accompanied by the arrival of control policies and measures.
