Zhejiang is mainly an export-oriented enterprise and has been hardest hit. The business goal of China's export-oriented sling companies in 2009 is only to maintain capital. In the Chinese market, due to the severe shrinkage of the main industries using slings, companies are calculating costs, their demand has decreased a lot, and their affordability has also continued to decline. Although the country has proposed revitalization plans for these industries, the demand for these industries cannot increase rapidly because the international climate is difficult to recover. It should be noted that as China continues to invest in new projects to stimulate domestic demand, such as nuclear power construction, wind power construction, railway and bridge construction, etc., the demand for slings has increased in these construction projects. In short, China's exports of slings will drop by more than 50% year-on-year in 2009, and domestic sales will also drop by more than 10%. Faced with the severe economic situation, competition in sling sales has become more intense. Some export-oriented companies, due to lack of experience in domestic sales, engage in price wars in order to survive, which seriously affects the healthy development of the sling industry.
