In recent years, with the advancement of the technological level and the enhancement of the strength of domestic manufacturers, domestic DCS manufacturers have made breakthroughs in each key industry and gradually penetrated into large-scale and super-large projects. In 2010, China's DCS market had fewer major projects and the price dropped seriously, resulting in relatively low performance of large foreign manufacturers, such as Emerson and ABB, while domestic manufacturers achieved good results under the support of national policies. Hollysys, Supon As well as Zhishen Zhishen, the growth of the company's performance was above 20%. The quality, technical capabilities, and engineering capabilities of domestic manufacturers are all recognized on the client side. The success of domestic manufacturers is closely related to the support of Chinese policies and the background of the company. For example, Helishi is a national brand that is supported by the state, and Guodian Zhishen backs the Guodian Group. Zheda Zhongzhong uses Zhejiang University as a strong technology. Judging from the types of projects, the domestic manufacturers of coal-fired power generation projects that acquired 100MW units have the national power Zhishen and Helishi; the domestic nuclear power project has achieved a breakthrough and favorable time (Guangli Nuclear), and has achieved a breakthrough in the conventional island non-safety level. At the security level, it is still the world of foreign manufacturers. In terms of petrochemical projects, Zhejiang Zhongzhong obtained a 10 million-tonne oil-refining project of Changling Petrochemical in 2009, which is the first time that domestic manufacturers have broken through 10 million tons of oil-refining projects; however, there is still no breakthrough in the million-ton-grade olefins sector, which has been achieved by domestic manufacturers. The integrated refining and chemical project is a major obstacle; in 2010, the State Power Zhishen achieved a breakthrough in the petrochemical field. At the same time, domestic manufacturers and foreign manufacturers still have insurmountable gaps. From the perspective of product line width, Emerson not only has Ovation and DeltaV DCS systems, but also has well-known instrumentation valve brands such as Rosemount, Micromotion and Fisher; ABB has 800XA also has its own Instrument production line. In the domestic large-scale MIV or MIC projects, domestic manufacturers will be shut out. From the project quality point of view, the industry’s iconic large-scale projects are still dominated by foreign companies. For example, Emerson, the power market's one million unit, occupies most of the time. Market share; large-scale projects in the petrochemical industry, mainly divided by Yokogawa, Honeywell, Siemens.
