Gaoshida brand curtain wall aluminum panels have been selected as the preferred brand by the top 500 real estate companies.

      In the face of new market environments and opportunities, in order to help real estate companies better understand the status and current situation of supporting industries, strengthen collaborative cooperation, and improve construction quality and cooperation efficiency, the China Real Estate Association and the E-House China Real Estate Assessment Center have launched the China Top 500 Real Estate Development Enterprises Preferred Brand Evaluation Research Report for eleven consecutive years based on evaluation research of real estate development enterprises and related industry chain enterprises. The aim is to assess competitive real estate suppliers and service brands through a scientific, fair, objective, and authoritative evaluation index system and evaluation methods.

      In terms of evaluation classification, this year's evaluation has been optimized and adjusted based on the demand for real estate procurement, dividing the supply chain into engineering categories (subdivided into civil engineering, installation engineering, and decoration engineering) and materials and equipment categories (subdivided into civil engineering materials, installation equipment, and decoration materials). In terms of the evaluation process, the preferred brand list for each sub-industry is mainly determined by the cooperation preference rate of the top 500 development enterprises, while also considering shipment volume and sales revenue, supplemented by expert nominations from industry associations, online voting for brand perception reviews, sampling surveys of engineering procurement personnel, and opinions from typical industry expert review meetings. The offline review meeting in 2019 particularly added dimensions to evaluate the marketing value and cost optimization value of enterprise products for projects, making it an important indicator for recommending cooperation. The types of preferred brand evaluations in 2019 added categories such as smart locks, formaldehyde-free artificial boards, and air treatment for decorated houses. At the same time, the evaluation of suppliers and service providers has been continuously refined, with the addition of subdivided field classifications based on the procurement focus of real estate companies, continuously introducing quality evaluation indicators. To obtain scientific, fair, objective, and authoritative evaluation results, an expert advisory group was established, and on December 14, 2019, review meetings were held in Shanghai, December 27 in Nanjing, December 28 in Guangzhou, January 4, 2020, in Qingdao, and January 10 in Beijing. Due to the impact of the pandemic, the online evaluation in Chongqing was launched for the first time on February 22. We sincerely thank Dahua Group, Zhengrong Real Estate, Yuexiu Real Estate, Sunac China, and Jinke Co., Ltd. for their strong support of the review meetings. Special thanks to the exclusive consulting support agency, China National Building Material Group Corporation, for providing the qualified rate data of key indicators for building material quality for this report.

Top 500 Preferred Civil Engineering Brands

      Preferred Brand Analysis: Currently, the assembly rate in major countries around the world exceeds 70%, with the proportion of existing prefabricated buildings in the United States and Japan reaching as high as 90%. In contrast, the proportion of newly built prefabricated building area in China in 2018 was only 9% of the newly built urban building area. In recent years, various regions have successively introduced supporting policies and set phased goals for the scale of prefabricated buildings, with Beijing, Shanghai, Shandong, Zhejiang, Jiangxi, and Sichuan proposing to achieve a prefabricated building proportion of over 30% by 2020. In terms of application, prefabricated construction is widely used, and the rise of long-term rental apartments in recent years is a case of industry application. The short construction cycle of prefabricated buildings perfectly matches the cost and efficiency requirements of large-scale production and long-term rental apartments. It is worth mentioning that during the construction of the Huoshenshan Hospital to combat the novel coronavirus pandemic, the use of prefabricated building technology played a significant role in saving time and promoted social awareness.

      Preferred Brand Analysis: The use of building curtain walls is widespread, mainly in commercial buildings, public buildings, and high-end residences. With technological advancements, various decorative panels can now be used in high-rise buildings, including aluminum panels, stainless steel panels, enamel panels, granite panels, and artificial boards in addition to glass. Thanks to the prosperity of the real estate and construction industries, after more than thirty years of development, China's building curtain wall industry ranks first in the world, and curtain wall design and construction technology have entered the ranks of developed countries. In terms of ultra-high-rise building curtain wall design, large-scale special-shaped curtain wall design, and BIM application, China has already made its mark globally. In recent years, the curtain wall industry in China has faced challenges and impacts due to real estate market regulation and fluctuations in raw material prices.

　　In the coming years, the doors and windows curtain wall industry will enter a period of stable development. The total market volume will continue to maintain steady growth. According to the "13th Five-Year Plan" development outline for the building decoration industry, by 2020, the total output value of China's building curtain wall projects is expected to exceed 500 billion yuan, with an average annual growth rate of over 10%. A market structure dominated by large enterprises and supported by small and medium-sized enterprises is forming. Currently, there are over 100 large enterprises in the industry, accounting for about 50% of the market share. The industry shows a trend of concentration towards leading companies. Large curtain wall companies have significantly increased their scale and output value by participating in the construction of municipal venues such as airports, exhibition halls, and sports venues, as well as large-scale and complex projects like corporate headquarters, while small and medium-sized enterprises face increasing development pressure, leading to polarization in the industry's operating conditions. The home decoration field and engineering market are gradually merging, with some brand real estate companies utilizing their advantages for resource integration, breaking down previous barriers between different fields. There have been significant changes in product structure, with prefabricated curtain walls gradually emerging.

      Preferred Brand Analysis: The driving factor for the amusement facilities industry is the increase in national income levels. With the rise in per capita income and the upgrading of consumption concepts, the demand for amusement facilities is increasing. The downstream application areas of the amusement facilities industry mainly include traditional amusement parks, theme parks, and urban complexes. The demand for amusement facilities in traditional amusement parks is stable, while the demand in theme parks is growing rapidly, and the demand in urban complexes is beginning to emerge. Research indicates that the retail sales of theme parks in China will reach 12 billion USD by 2020. The domestic amusement facilities industry has a large number of enterprises, but the individual scale is small, and the industry concentration is relatively low. Currently, there are about 240 amusement equipment manufacturing companies in China, of which about 80 have the qualification to produce large amusement facilities. Although the concentration is not high, there are certain entry barriers in the industry, including operational qualifications, technology and talent reserves, content IP, and safety barriers.

      Preferred Brand Analysis: According to the latest data on motor vehicles and drivers released by the Traffic Management Bureau of the Ministry of Public Security for the first half of 2019, as of June 2019, the total number of motor vehicles in the country reached 340 million, including 250 million cars; the number of motor vehicle drivers was 420 million, of which 380 million were car drivers. The number of private cars reached 198 million. Multi-storey parking garages are classified into various types based on different scenarios, including flat moving type, simple lifting type, vertical lifting type, and vertical circulation type. The biggest advantage of multi-storey parking garages is saving land space, which can effectively improve the efficiency of land area usage, thus having broad development prospects. Residential communities are the largest customers of multi-storey parking equipment. Many domestic double-decker parking spaces are still in the planning stage, with only a few being truly utilized. With the continuous advancement of "old renovation," multi-storey parking garages can utilize the corner areas of communities, and it is expected to find new market development space.

      Preferred Brand Analysis: In 2019, there were approximately 2,446 companies in the national swimming pool equipment industry. The industry is in a development stage from quantity to quality, with various unique swimming pools emerging. For example, infinity pools, sky pools, portable pools, and so on. In particular, sky pools have become a selling point for real estate projects. A swimming pool on the top floor of a community, suspended like a bridge in mid-air, allows visitors to look down through tempered glass, but only community owners have the right to use the pool. This unique experience enhances the value of the community. The implementation of the new swimming pool water quality standard CJT244-2016 has forced companies to upgrade their water treatment technologies, such as diatomaceous earth filtration technology and full-flow ozone disinfection systems, making filtration and disinfection more efficient than before, and continuously improving overall water quality.

      Preferred Brand Analysis: The external wall decoration industry has a low entry barrier, and currently, there are mainly three types of companies in the industry: construction decoration companies focusing on large public building decoration projects, coating companies that drive construction through the sale of paint products, and construction teams with high personnel turnover. The industry shows a pattern of a large market with many small companies, and few large enterprises. According to the statistics published by the China Architectural Decoration Association in the 'China Architectural Decoration Blue Book', the number of construction decoration companies was about 145,000 in 2011, which decreased to 125,000 by 2018, with 20,000 low-quality small enterprises exiting the market, leading to a gradual concentration towards leading companies. In recent years, new coating process technologies have developed rapidly, with robotic coating and intelligent construction becoming important directions for future coating development. At the same time, people are increasingly concerned about environmental protection, making energy-efficient buildings a market focus. Using lightweight wall materials to improve the thermal insulation performance of building envelopes has become an important measure for building energy efficiency. High-quality companies adopt systematic solutions to improve external wall quality and address industry pain points, but the market also has some small and medium-sized enterprises cutting corners on raw materials and engaging in bottomless price competition, adding chaos to the industry.
