Prefabricated construction refers to the type of building in which prefabricated components such as walls and composite panels are produced and manufactured according to standards in the enterprise workshop, transported to the construction site, and mechanically assembled for installation. It is commonly understood as a “modular” type of building, which is mainly classified into prefabricated prefabricated concrete structures (PC buildings), steel structures, modern wooden structures, etc. Prefabricated buildings are mainly supported by four major systems, each with different characteristics, and it is precisely because of their advantages that they are able to build prefabricated buildings with many advantages..

Prefabricated wooden structure buildings refer to wooden structure components such as walls, roofs, and floors that are prefabricated in factories and assembled on-site. The main characteristics of prefabricated wooden structures are: a large amount of on-site construction is transferred to factory production; Computer assisted manufacturing; The quality control of the house has been moved from the construction site to the factory, meeting strict quality certification management requirements..

From the perspective of the global development of prefabricated buildings, the 19th century was the germination period of prefabricated prefabricated buildings, with representative works including Crystal Palace, prefabricated wooden houses that meet the needs of immigrants, prefabricated iron houses, etc. After World War II, there was severe damage to buildings, a large number of demobilized soldiers, and a tight demand for housing, leading to a period of vigorous development in the industrialization of construction. Each country should develop prefabricated building systems with its own characteristics according to its own architectural system, socio-economic level, geographical environment, and technological level. Overall, the global construction industrialization has gone through four stages of development. At present, the world is actively exploring BIM (Building Information Modeling) technology and 3D printing technology, continuously applied in the field of prefabricated buildings..

In January 2022, the Ministry of Housing and Urban Rural Development issued the “14th Five Year Plan” for the development of the construction industry, which pointed out that during the “14th Five Year Plan” period, prefabricated buildings accounted for more than 30% of newly built buildings. Therefore, during the “14th Five Year Plan” period, efforts will be made to develop prefabricated buildings, improve the structural building standard system, improve the pricing basis for structural building projects, and guide the coordinated development of upstream and downstream industrial chains. The strong support from the policy side for prefabricated steel structure buildings is expected to bring significant growth to the demand for prefabricated wood structure buildings in the field of public buildings..

The upstream of prefabricated wooden structures mainly includes wood, production equipment, prefabricated wooden components, and other production raw materials; The midstream is a manufacturing enterprise for prefabricated wooden structures; Prefabricated timber structures are mainly used downstream in light timber structure buildings, glued timber structure buildings, heavy timber structure buildings, timber structure composite buildings, and post maintenance markets..

The global timber structure construction market has maintained stable growth overall, with the sustained development of industries such as hotel accommodation and retail in emerging market economies, as well as prefabricated timber structure residences in Europe, the United States, Japan and other regions, remaining the main driving force for industry growth. In 2022, the global timber structure construction market reached a size of 21.58 billion US dollars. Thanks to the abundant reserves of timber resources, more mature wooden structure prefabricated building technology, and the advantages of vast land and sparse population, as well as a high number of single family buildings, the global wooden structure prefabricated building market is mainly concentrated in North America and Europe, followed by Japan in Asia,.
