The products of dry-type transformer cooling fan industry belong to a part of general machines. After participating in WTO construction, the impact on the products of machines, including the impact on the products of dry-type transformer cooling fan. The impact on the mechanical equipment of dry-type transformer cooling fan is mainly divided into the following three environments.

        1. Production of labor-intensive products or products of low cost, with a cost industry. The products of such industries, due to the competitiveness formed in the market, will expand exports after participating in the WTO structure, and the market opening will not pose a threat to these industries at all.

        2. Resources and intensive or relatively intensive industries are respectively affected by different degrees, resulting in different enterprises and multinational companies having joint stock or mutual assistance with Chinese enterprises, If the product price of its production is somewhat (i.e. lower than the selling price of the low import tariff of the import product in China), after the opening of the market in China, unless there are new strong competitors coming in, there will not be much impact in general; on the contrary, because the joint-stock enterprises still enjoy "national treatment" in terms of tax revenue, and the import tariff of the key components for production will be lower, which will further lower the production The cost is competitive. There is a gap between the product skill level and foreign countries, but the gap is not very large, and the cost is significant. The product of this kind of industry, after the market opens up, suffer not big degree. If the high-tech property and the newly developed high-tech products do not have the ability to compete, or the cost is higher than the market cost of the enterprise, they will be greatly hit.
