Abstract: New urbanization constitutes a crucial component of China’s modernization drive, facilitating industrial upgrading and economic structural transformation. As a pivotal industry underpinning new urbanization development, the construction sector plays a vital role in enhancing residents’ quality of life, advancing infrastructure development, and mitigating employment pressures during this process. The construction industry and new urbanization exhibit mutual interactions and influences, with their coupled and coordinated development emerging as a critical pathway toward achieving national economic development and social progress. Leveraging panel data from 31 provinces spanning 2013-2022, this study employed the entropy value method and coupling coordination model to evaluate the level of coupled and coordinated development between China’s construction industry and new urbanization. The findings reveal that China’s new urbanization development level surpasses that of the construction industry, while the coupling and coordination index between the two demonstrates an upward trend, yet remains marginally coordinated overall. Regional disparities in the development of the construction industry and new urbanization are evident, with the east-central region exhibiting higher levels of coordinated development compared to the western and northeastern regions.
