Examining Construction Process Improvements to Drive Growth in the Wooden Construction Industry Through Importance-Performance Analysis

Promoting wooden construction can significantly reduce carbon emissions by storing carbon in wood materials and replacing carbon-intensive materials like concrete and steel. However, the domestic wooden construction industry remains small in scale. While various strategies have been suggested to revitalize this sector, they often lack a comprehensive understanding of the construction process and detailed implementation plans. This study examines the construction process through in-depth literature reviews and expert interviews, identifying issues at each stage and proposing measures to strengthen the wooden construction industry. An Importance-Performance Analysis (IPA) based on expert surveys was conducted to evaluate the significance and effectiveness of these measures, leading to the development of short-term and long-term strategies for stimulating wooden construction. In the short term, it is crucial to establish support policies linked to carbon incentives, standardize information and classification systems for materials and wooden components, and quantify the benefits of wooden construction through performance data collection. Long-term strategies focus on achieving cost and productivity competitiveness through mass production systems and the localization of wooden construction materials. These findings aim to identify the barriers to the growth of wooden construction and provide a foundation for effective policy recommendations.
