1. Industry characteristics: The main products in the instrumentation industry include various types of smart electricity meters, long-life electricity meters, induction-type electricity meters, smart meters designed for charging stations, smart gas meters, mechanical gas meters, digital instruments, analog instruments, and temperature control instruments. Among them, electricity meters are the dominant products in the electrical instrumentation industry, accounting for about 90% of the total output of this industry. At present, China ranks first in the world in terms of the production and sales volume of electricity meters, with manufacturing enterprises mainly located in provinces and cities such as Zhejiang, Jiangsu, Hunan, Guangdong, and Shanghai. In 2011, the production volume of electric meters in China reached approximately 123 million units, with an output value of around 13.5 billion yuan. There is no cyclical or seasonal pattern in the electricity meter industry; electronic meters have become the mainstream in the market. **Power grid companies will no longer purchase induction meters on a large scale going forward. Inductive electricity meters are used in some rural areas, while electronic smart electricity meters are primarily used in urban areas. The general trend in the development of this industry is toward higher sophistication and intelligence. 2. Industry concentration and competitive landscape (1) Industry concentration: Electric meters are the dominant products in the electrical instruments industry, accounting for around 90% of the total output in this sector. Electricity meters are primarily used in power systems and integrated markets: Power systems mainly include **the power grid, the Southern Power Grid, and the affiliated power companies, which account for around 70% of the total purchases ； Purchases from comprehensive markets account for about 30%, and most of the purchasers from these markets ultimately sell their products to the power grid as well. Overall, 80%-90% of electricity meters are used in power grids. With the advancement of **smart grid development** and the maturation of the grid recruitment system, in order to adapt to the new market competition landscape, establishing cooperative relationships with **grid companies** through mergers, reorganizations, and integrations has become an effective strategy for leading manufacturers in the instrumentation industry to gain a competitive advantage. Manufacturers of electricity meters across the country tend to concentrate, and in the end, only a dozen or so companies bid on the projects. In the future, this pattern is likely to continue and intensify, with an increasing degree of concentration. (2) Industry competition landscape: In the high-end segment of the domestic electricity meter market, multinational companies hold a monopoly position; for example, Landis+Gyr has an absolute monopoly in the area of substation meters. The mid-to-low-end market is dominated by companies such as Ningbo Samsung Electric Co., Ltd., Winsun Group, Huali Instrument Group, Shenzhen Haoningda Instrument Co., Ltd., Shenzhen Kelu Electronics Technology Co., Ltd., Jiangsu Linyang Electronics Co., Ltd., and Chint Instruments, which together account for approximately 52.6% of the market share. **Following the centralized recruitment by power grid companies, the market share of leading enterprises in the specialized market was seized by some smaller and medium-sized manufacturers, pushing industry competition to an intense level. Integrated markets will gradually decrease, giving way to markets based on regular admissions; this trend intensifies competition in those markets while also leading to greater concentration within the industry. 3. Industry demand and future development trends: In accordance with the unified plans set by the State Council, during the 12th Five-Year Plan period, both the national power grid and the Southern Power Grid will carry out new rounds of projects to upgrade rural power grids; it is estimated that over 500 billion yuan will be invested in the construction of such new rural power grids. **The \"12th Five-Year Plan for Science and Technology\" for the power grid and Southern Power Grid has been released, stating that high technology should be used to address the challenges faced by intelligent (green) power grids, in order to achieve the goals of energy conservation and emission reduction in the power sector. Among them, the technological requirements in the field of intelligent power distribution and consumption have also been clearly defined, namely: new types of intelligent power distribution equipment, intelligent power distribution terminals, intelligent analysis and rapid simulation methods for power distribution networks, intelligent interactive power consumption service systems, power consumption information collection and advanced measurement technologies, interactive customer services and utilization of customer resources, distributed energy management, energy efficiency management and intelligent power consumption communities, electric vehicle charging and discharging technologies, as well as intelligent power consumption monitoring and simulation technologies. From the perspective of product development trends, induction single-phase meters still account for a certain proportion among users in rural power grids, while smart meters have been widely adopted among users in urban power grids. According to the 2011 report on the development of the electrical measuring instruments industry, electronic electricity meters account for 85% of the market share. With the rapid development of high-tech technologies, especially electronic information technology, the advantages of single-three-phase intelligent, multi-rate, high-precision, and automatic meter reading products have become evident, and they have gradually become the mainstream in the development of electricity meters. From 2009 to 2020, power grid companies advanced the construction of smart grids in three phases: planning and piloting, comprehensive construction, and leadership and improvement. The advanced metering system (AMI), which includes smart electricity meters, was a key focus area for smart grid development during the 12th Five-Year Plan period. **The power grid company plans to invest 46 billion yuan over 4-5 years in the purchase of smart electricity meters. It is estimated that the annual market demand for such meters during the 12th Five-Year Plan period will be around 80 million units, of which 50 million will be single-phase smart meters, 6 million will be three-phase and multi-functional meters, and 24 million will be meters for use in rural power grids.
