In the context of the overall slowdown in the growth of the industry, the sub industries of the machinery industry have been differentiated. According to the statistical data of the first five months, the container, bearing and valve, agricultural machinery, metallurgical mining equipment, motors, general instruments and meters, and boiler manufacturing industry continued to maintain a high boom, and the growth rate of the total accumulated profits remained above 40%; However, several sub industries, such as special instruments and meters, electronic measurement, measuring instruments and construction machinery, experienced a decline in sales revenue and a significant decline in profits; Against the background of declining overall prosperity of the machinery industry, the two sub industries of the railway transportation equipment and shipbuilding industry have turned from past losses to profits, and the industry shows obvious signs of recovery.
In the machinery industry, basic parts such as bearings, valves, general parts and components are the upstream industries of most mechanical equipment. The slowdown of macroeconomic or fixed asset investment will first lead to the slowdown of the demand for large-scale mechanical equipment, and then affect the upstream basic parts industry. Therefore, in general, The prosperity of basic parts lags behind that of mechanical equipment.

Against the background of the slowdown in the growth rate of the whole machinery industry, it is expected that the special equipment manufacturing industry, instrument manufacturing industry and transportation equipment manufacturing industry, which fell significantly in the first half of the year, will tend to be stable in the second half of the year; Affected by the lag effect, the general machinery manufacturing industry (including boilers, metal processing machinery, general equipment, bearings and valves, and other general parts and components) will decline more in the second half of the year, exceeding the industry average.
Some sub industries, such as container, bearing and valve, motor and general instrument manufacturing, whose prosperity is still high due to lagging and other reasons in the early stage, are cautious. It is expected that the above sub industries may reach the boom peak in the short term, and then there will be a certain degree of decline. However, sub industries such as construction machinery, which declined significantly in the early stage, may recover to a certain extent due to a smaller base. The railway transportation equipment and shipbuilding industry are expected to continue to maintain an upward trend.
