Salt spray test chamber needs to cultivate and protect the domestic market

China's manufacturing industry is a low-end manufacturing industry in the international division of labor. In recent years, it has been due to rising wage costs, rising raw material prices and shrinking overseas markets. The entire Chinese manufacturing industry is in a sandwiched state where there is a blockage before and a "chaser". The development of China's high-end manufacturing industry has been unable to make breakthroughs in core technology and high-end equipment's own technology. What is the reason?

The salt spray test chamber is the best mirror in history. At present, all high-end industries in developed countries have grown through the protection, development and monopoly of the domestic market. The most prominent example is the United States. Therefore, economist Adam Smith said that the United States is not suitable for industrial development. But at the time, the visionary politicians in the United States believed that without industrial development, the country's independence and security could not be guaranteed. At that time, the new industry in the United States was undoubtedly a high-end manufacturing industry, but both the cost of wages and the cost of capital were higher than those of European countries, and the quality of products could not compete with the latter. American historian Faulkner pointed out that until 1850, the vast majority of American general manufacturing was still carried out through domestic labor or through private shop owners who hired apprentices. Under such circumstances, it was impossible for American industry to have overseas markets. Under such circumstances, how will American industry develop?

For the salt spray test chamber, Faulkner said that the United States can only rely on the domestic market, and there is no other way. Therefore, the United States has implemented policies of high tariffs and exclusion of foreign direct investment, keeping foreign industrial products out of the country ’s borders, and allowing new national industries to monopolize the domestic market. Because the United States has a large domestic market, this irreparable protection has not harmed the fierce domestic free competition, but it has led to the rapid rise of emerging industries such as American steel and heavy machinery, which has made the United States replace the United Kingdom and become the second time. Pioneer of the Industrial Revolution. And another American economic historian wrote that the tone of American economic policy was to preserve the domestic market for domestic manufacturers from the outset and to exclude foreign competition.
