The data recently released by the National Bureau of Statistics shows that from January to April, investment in urban fixed assets was 2,229.4 billion yuan, up 25.5% from the same period of last year, and its growth rate was up from the first quarter. In April, the added value of industrial enterprises above designated size continued to grow by 17.4% year-on-year; total retail sales of consumer goods reached 667.3 billion yuan, a year-on-year increase of 15.5%.

For example, the central bank recently raised the reserve requirement ratio and interest rate of the renminbi again. It is expected that it will continue to maintain steady and rapid growth in the later period.
