Research on dissipative structure of China's green building industry system based on Brusselator model

Abstract

With the introduction of the “Double Carbon” initiative, the urgency to develop green buildings in China has become paramount. The green building industry aims to reduce energy consumption and carbon emissions while fostering its rapid growth. However, several challenges still hinder the industry's progress. Therefore, this study employs dissipative structure theory to examine whether the green building industry can transform from a disordered state to an ordered state by continuously exchanging material, energy, and information with the external environment. By establishing the industry structure, 13 internal indicators and 10 external indicators are identified through a comprehensive literature review. The Brusselator model and entropy method are applied to calculate the system entropy using questionnaire data. The results indicate a positive entropy value (A) of 0.67823, while the negentropy value (B) is −1.438553. Clearly, the relationship between positive entropy and negentropy does not meet the critical condition B>A2+1, which validates that the current green building industry in China is not a dissipative structure. This finding signifies that the industry faces challenges in achieving sustainable and stable development. Consequently, based on these calculations, five effective strategies are proposed to facilitate the transformation of the green building industry into a dissipative structure and promote its sustainable and healthy development. The research findings serve as a valuable reference for the Chinese government in formulating laws and regulations pertaining to the green building industry, thereby facilitating its comprehensive and effective management and aiding the achievement of energy conservation and emission reduction goals in the construction sector. This study contributes to expanding the application of dissipative structure theory in the green building industry and enriches the theoretical foundations of research on the industry from the perspective of complex systems.
