Promoting additive construction in fast-developing areas : an analysis of policies and stakeholder perspectives

Abstract

Construction 3D printing (C3DP) has emerged as an important force in automation and sustainable transformation of the construction industry. Despite the implementation of numerous incentive policies, its development and application remain at a relatively slow pace in developing countries. This research employs the Q methodology to explore the perspectives of China's stakeholders on the innovation policies for the development and application of C3DP. The study reviews the development of C3DP in China and identifies statements related to C3DP promotion policy and development. Based on data from C3DP industrial experts, the results reveal four distinct policy perspectives: conservative exploration, aggressive progression, intensive investigation, and tentative stimulation. A consensus exists that provides direction for policymaking though the divergences among stakeholders highlight the complexity of implementing policy mixes. This study has theoretical and practical significance in supporting policy mixes for C3DP development and adoption in fast-growing areas.
