Mechanical and electrical products are a strong support for China's export economy. With the acceleration of the industry reshuffle in recent years, in order to improve their own strength and expand the international market faster, domestic mechanical and electrical enterprises will accelerate the integration with foreign enterprises through a variety of means to improve product quality and competitiveness. Under the situation of accelerating the speed of international integration, foreign-funded enterprises are upgrading products faster and faster, new products and new technologies keep emerging, and their strength is getting stronger and stronger. However, domestic enterprises are overwhelmed by the disordered competition in the domestic market. Some enterprises that do not adapt to the market competition will launch the market competition through different channels. Therefore, the two-level situation of mechanical and electrical enterprises will become increasingly fierce, and the mechanical and electrical giants will emerge day by day.

Although the export of mechanical and electrical equipment is growing well, according to the survey of enterprises by China Chamber of Commerce for Import and Export of Mechanical and Electrical equipment, the cost of enterprises is rising, the pressure is increasing, and the profit is declining. Most enterprises believe that the main factors leading to the cost increase since last year are the price rise of raw materials, the rapid appreciation of RMB and the rise of labor price, and the growth rate is higher than the expectations of enterprises, especially the appreciation rate of RMB since this year is much higher than the expectations of enterprises. At the same time, export tax rebate and interest rate rise are also important factors affecting the increase of enterprise costs.

With the change of international and domestic situation, the development of China's strategic emerging industries is facing great challenges. Construction machinery industry as a strategic emerging industry, rapid development in recent years, construction machinery industry market is also becoming mature, electric push rod enterprise competition, promote the reform of the industry from time to time, but there are still several constraints, need to break through. Lack of core technology, many core technology depends on foreign countries, this is our construction machinery industry, especially the development of high-end equipment manufacturing industry meets the biggest bottleneck. First of all, we must adhere to independent innovation, take the road of maintaining and developing national brands, and break out our own world in the competition with foreign brands.

The electric push rod type cantilever crane has initially formed the R&D and manufacturing system of main engine products, basic technology and functional components at the international frontier level. China's equipment manufacturing industry should focus on industrial optimization and upgrading, shift from production to service, consolidate the industrial base, solve the problem of lagging development of basic components, foster emerging industries, and improve the capacity for independent innovation. From large to strong "national high-end equipment manufacturing industry development concept, at the same time, our construction machinery industry only exert the cluster effect and brand effect, to walk out of a unique international road. It indicates that the intellectual property barriers of foreign leading enterprises in the field of hoisting machinery have been gradually conquered by Chinese independent intellectual property rights. Domestic construction machinery enterprises have broken the monopoly of foreign crawler cranes for 3000t class, and domestic super-large tonnage crawler cranes have been published. Standing on the forefront of the global hoisting machinery industry, at the same time, this also marks the level of Chinese construction machinery research and development into a new height.
