Domestic alternatives enhance brand competitiveness
It is understood that the global industrial robot market has long been a market share of more than 50% of the four major families of Japan Fanuc and Switzerland abb, Japan Yaskawa and Germany Kuka. In recent years, the competitiveness of domestic independent brands has been significantly improved, and the inventory of industrial robots has grown steadily. The installed capacity of domestic industrial robots ranks first in the world, but there is still a lot of room for improvement in installed density.
As foreign giants such as ABB and Yaskawa compete to strengthen the Chinese market, traditional robot manufacturers, technology giants, manufacturing giants, new companies, core components, intelligent equipment and other key technological breakthroughs, the process of domestic robot substitution is further accelerated, and the market may enter the era of short-term connection.
In 2021, the domestic industrial robot brand will have a market share of domestic shipments32.8%, a year-on-year increase of 4.2%。 The main reasons include, on the one hand, that foreign-funded enterprises have been affected by the epidemic in terms of production, delivery, after-sales service, etc., and their comprehensive competitiveness has been reduced. In the face of the opportunities brought by the epidemic, domestic robot manufacturers have quickly seized the original market of foreign capital with their strong technology and service capabilities, and the localization process has been further accelerated, and the share of core industrial control products is expected to continue to accelerate.
On the other hand, the development momentum of domestic head robot manufacturers is good.
