Almost all the world's mainstream construction machinery manufacturers have entered the Chinese market, or joint venture or sole proprietorship. Moreover, a considerable number of multinational companies have shifted their focus from Asia Pacific to the world to the Chinese market, and the market competition is very fierce. From this point of view, the construction machinery market in China has been internationalized, as can be seen from the exhibition in 2010. Sumitomo, which has been mainly importing original machines, has also set up a factory in Tangshan, and more and more imported machines will be imported, with an annual output of 5000 in 2012.
