"Promoting quality with new" builds the foundation for the high-quality development of the construction industry

Only backward technology and products, there is no backward industry. Traditional productivity is the foundation, and new quality productivity is the key. New quality productive forces and traditional productive forces have both substitution and complementarity relations. Emerging technologies inject new scientific and technological genes into traditional industries, reflecting the "transition" of qualitative dimension.

As a traditional labor-intensive industry, the development of "new quality productivity" is to bid farewell to the old technology system, get rid of the traditional growth path, and drive the industrial system with scientific and technological innovation to "quality" change, and "promote quality with new" to build a foundation for the high-quality development of the construction industry.

It is a general trend for the construction industry to develop new quality productivity

New-quality productive forces are modern advanced productive forces created by revolutionary technological breakthroughs, innovative allocation of production factors, and deep industrial transformation and upgrading. They are productive forces formed by the latest modern technologies, especially under conditions such as information technology, intelligence, and networking. They are productive forces that reshape the mode of production and way of life and bring about high-quality life through high-quality development. It is a productive force that takes scientific and technological innovation as the guide and comprehensively improves factor production efficiency and total factor productivity.

In the final analysis, the productive forces are still composed of three elements: laborers, means of production and objects of labor. It is urgent for the construction industry to develop new quality productivity. In terms of labor, the problem of "aging" of construction workers has become increasingly prominent, and construction enterprises may face the problem of "difficult employment" for a long time. In terms of labor materials, the extensive excavation of stone and river sand is no longer, and the raw materials of construction industry have undergone fundamental changes; In terms of labor objects, from "having a house to live in" to "living in a good house", people's requirements for the quality of housing have been greatly improved.

Therefore, the development of new quality productivity in the construction industry is the general trend. Its significance mainly has three points: First, it is an inevitable requirement to promote the transformation and upgrading of the construction industry and achieve high-quality development. For a long time, China's construction industry mainly relies on the input of resource factors and large-scale investment to drive the development, and the integration of the construction industry with advanced manufacturing technology, information technology and energy-saving technology is not enough. The construction industry urgently needs to accelerate the coordinated development of intelligent construction and construction industrialization, integrate new technologies such as 5G (fifth generation mobile communication technology), artificial intelligence, and the Internet of Things, and form an intelligent construction industrial system that integrates the whole industrial chain including scientific research, design, production and processing, construction and assembly, operation and maintenance, and develop new quality productivity in the construction industry. Second, important measures to effectively stimulate domestic demand and stabilize economic growth. Promoting the coordinated development of intelligent construction and building industrialization can give birth to new industries, new formats and new models, and provide application scenarios for the deep integration of cross-field, all-round and multi-level industries. This work not only has huge investment demand, but also can drive a huge consumer market, help speed up the formation of a strong domestic market, and is an important measure to effectively ease economic pressure and strengthen new drivers of development. The third is to conform to the international trend and enhance the international competitiveness of China's construction industry. Compared with the intelligent construction technology in some developed countries, there is still a certain gap, and it is urgent to promote the coordinated development of intelligent construction and building industrialization as a strategic choice to seize the future scientific and technological development of the construction industry, and enter the ranks of the world's intelligent construction powers by promoting the industrialization, digitalization and intelligent upgrading of buildings.

"Three high" to achieve new quality productivity

New quality productivity is embodied in the "three high", namely: high-tech, high performance, high quality. Specifically, it is necessary to intelligent production methods, digital management methods, and green terminal products.

For the construction industry, intelligent construction is an important embodiment of "new quality productivity". "Visible in the factory, invisible in the cloud", intelligent construction builds a digital, information, intelligent advanced construction method, the visible construction process is placed in the factory, the bulk building materials through large-scale, integration, industrialization of intelligent manufacturing, on-site assembly is mainly organized construction; The invisible construction organization process is placed on the cloud, and through digital technology and digital management, the whole process of design, production, transportation, construction and operation and maintenance is promoted. This construction method promotes the realization of the construction industry's "capacity upgrading, capital aggregation, and industrial cluster", thus promoting the high-quality development of the digital transformation of the construction industry, creating a new engine of economic development, and is a strong demonstration of "new quality productivity" in the construction field.

The basic connotation of the new quality productivity is the qualitative change of workers, labor means, labor objects and their optimal combination. As for workers, we must speed up the construction of a talented workforce. It is necessary to cultivate high-end talents in short supply, smooth the virtuous cycle of education, science and technology and talents, build a diversified training system, and establish a sound incentive mechanism to strengthen the cultivation of professional talents and vocational training of industrial workers. As for labor materials, we should strengthen technological innovation and innovate management mechanism. Labor materials are all material materials or conditions used by workers to change or influence the object of labor in the process of labor. In the construction industry, the innovation of labor materials is mainly reflected in the innovation of science and technology and management mechanism. In terms of scientific and technological innovation, it is necessary to strengthen technological research in key fields, cultivate the innovation platform of intelligent construction, and promote the standardization of intelligent construction. In terms of management mechanism, it is necessary to innovate the government management model, promote the advanced management model of engineering construction, promote the digital delivery of engineering projects, and establish an intelligent construction evaluation system. For the labor target, to build an industrial ecology, the implementation of pilot projects. The innovation of labor object in the construction industry is mainly reflected in the construction of industrial ecology and the implementation of pilot projects. The construction of industrial ecology mainly includes digital design, digital twin platform, modular intelligent manufacturing, intelligent production, intelligent construction equipment, intelligent construction and intelligent operation and maintenance industry chain. The implementation of pilot projects mainly includes publishing the intelligent construction technology catalog, carrying out the intelligent construction project pilot, promoting the multiple application of intelligent construction technology, and supporting the construction of intelligent construction projects.

Use ecological "green content" to enhance the "gold content" of development

In recent years, the national and local levels have successively issued many policy documents to promote the development of new building industrialization represented by prefabricated buildings. The "14th Five-Year Plan" proposes to "develop intelligent construction, promote green building materials, prefabricated buildings and steel structure housing." The "14th Five-Year Plan for Building Energy Efficiency and Green Building Development" issued in 2022 clearly calls for "promoting new green construction methods." Vigorously develop steel structure buildings, and develop wood structure buildings according to local conditions."

Steel structure and wood structure buildings naturally have the excellent genes of new building industrialization and the characteristics of green buildings. The main advantages of steel structure buildings are high strength, light weight, fast construction, low resource consumption, and recyclable. The development of steel structure is not only an important way for the construction industry to implement the national "double carbon" goal, but also an effective way for the steel industry to optimize the consumption structure of construction steel, reserve steel strategic resources, and achieve high-quality development. In the past five years, the compound annual growth rate of China's steel structure construction market is about 10% or more, but the domestic steel structure construction area accounts for only about 5% to 7% of the total construction area, which is a large gap from 30% to 40% in developed countries, and China's steel structure is mainly used in the field of super high-rise and large-span construction, accounting for nearly 80% of all application scenarios. The proportion of steel structure housing is very low, and there is still a large space for development. In the future, the steel structure industry will develop to the high-end of steel structure products and technical standards, the intelligent production and manufacturing of steel structure, and the green direction of the full life cycle of steel structure. It is suggested that the government continue to strengthen policy guidance, especially in the renovation of urban villages and the construction of affordable housing, vigorously promote the demonstration application of steel structure housing, and adopt rapid assembly steel structure in military facilities and disaster prevention and reduction projects.

Wood is recognized as a sustainable, renewable, reusable and degradable building material, with light weight, easy processing, health and comfort, low comprehensive cost, carbon reduction and energy saving effect. In recent years, although the modern wooden structure has gradually entered the public vision, the development is still slow, mostly concentrated in tourist real estate, homestayers, exhibition halls, antique renovation and other specific scenes or informal construction buildings. Nowadays, under the national "double carbon" goal, the advantages of carbon reduction, carbon storage and carbon reduction of wood structure buildings have gradually attracted the attention of society. China has abundant biomass resources, appropriate cutting and utilization and re-cultivation, can form a virtuous cycle. If the development and promotion of these species of wood for the manufacture of new engineered wood products, can achieve value-added, while greatly improving the carbon storage of buildings, truly achieve "sustainable wood construction, build carbon neutral".

The development of wood structure buildings, one is to strengthen the relevant research on wood structure building materials and carbon emissions in the construction field, and provide good technical support and policy support for the development of modern prefabricated wood structure buildings in our country. The second is to give play to the advantages of wood structure buildings, adapt to local conditions, and actively promote. In addition to villas and resorts, wooden structures can also be used for multi-high-rise residential buildings and various public, business and leisure places, such as shopping centers, exhibition centers, schools and office buildings, as well as cost-effective old renovation projects. The third is to develop the key technology of wood structure, revise the standard specifications suitable for the development of wood structure, such as revising the relevant fire regulations.
