The current research on photovoltaic building integrated technology is mainly focused on its application prospect and development trend from the perspective of policies, regulations and technology, while rarely on the multi-level correlation inquiry from governmental policy, management, economy and other influencing factors. In view of an inquiry into the influencing factors on BIPV development and the interrelationship between them, combined with the expert discussion method and literature reading, a hierarchical structure chart has thus been established by adopting the interpretive structure model, with the weight of each index calculated using the analytic hierarchy process. On the basis of a consistency test, it is learned that the degree of policy incentive, the degree of norms and standards, and the perfect degree of laws and regulations are the deep factors affecting the integrated development of photovoltaic buildings; the development degree of photovoltaic technology, the industry financing risk, and the stakeholder benefit distribution mode are the intermediate factors, while the development enthusiasm of the construction unit is the surface factor. The three layers of factors are interrelated, affecting the integrated development of photovoltaic buildings in varying degrees. It is suggested that the relevant legal and regulatory system should be improved, a scientific and efficient management model should be established, and the willingness of consumers and developers should be enhanced for the acceptance of the proposed technology, so as to promote the development of this technology.
