For the spring industry, the supply of low-grade ordinary springs exceeds the demand for a long time, and the supply of high-grade products (high strength, high stress, dissimilar parts and special materials) exceeds the demand. The output of China's spring industry has become saturated. According to experts' statistics, the annual production of springs in China has reached 4 billion pieces. There are 21 categories and more than 1600 varieties of various spring products, mainly including valve springs, suspension springs, diaphragm springs, shock-absorbing springs, hydraulic springs, oil pump springs, disc springs, high-temperature springs, snap springs, tension springs, torsion springs, compression springs, scroll springs and heterosexual springs. During the "Eighth Five Year Plan" and "Ninth Five Year Plan", the spring industry developed rapidly, especially in Shanghai, Tianjin, Guangzhou, Shandong, Changchun, Chongqing and other regions. Other regions also developed to varying degrees, which is generally better than other industries. Automobiles, motorcycles, mopeds, internal combustion engines, electric appliances, instruments, etc. need to be developed. The development of these industries will drive the development of the spring industry. In the face of the macroeconomic situation, the contradictions of low product quality, loose organizational structure and weak development capacity formed by the industry over a long period of time have become more prominent. From the deep-seated perspective, it is mainly the problems in the market, system and mechanism. The industrial insight researcher believes that with the transformation of the national economy from the seller's market to the buyer's market, some deep-seated contradictions, especially the structural contradictions accumulated over the years, have become increasingly prominent. At present, the irrational industrial structure is manifested as follows: the production capacity of some industries is excessive, and the product structure is unreasonable; Unreasonable technical structure and low level of main industrial equipment; The enterprise organization is small and scattered, lacks competitive strength and advantages, and the regional structure is similar, which fails to reflect comparative advantages and cooperative benefits.
