Abstract
Nationwide energy efficiency (EE) promotion of new residential buildings is affected by multiple factors regarding policies, markets, technologies, capacities, and economics. The perceived influences of these factors by stakeholders are crucial to the effectiveness evaluation of current policies and the selection of policy instruments. However, they are normally assumed or taken for granted. The knowledge gap between stakeholders’ perceptions and research assumptions may lead to researchers’ recognition bias. Correspondingly, this paper aims to identify the significant factors, perceived by frontline stakeholders, influencing nationwide EE promotion of new residential buildings before 2020 and 2030. Factors were collected through literature review and their influence were evaluated via Analytical Hierarchy Process based on the data collected in the questionnaires distributed to 32 institutes. The theory of Nested Policy Design Framework and Policy Environment was used to structure the hierarchy and generate policy implications. Results indicate that (1) policy factors are of the greatest influence before 2020 and market perfection factors will have great influences from 2020 to 2030, indicating the transformation of governance arrangement to “market-based” and “network-based” from the current legal-based system; and (2) factors regarding market needs are of significant influence in both terms, revealing the way the transformation should be accomplished.

Summary
China’s unprecedented socio-economic development and fast urbanization (see Figure 1) has driven great expansion of residential buildings. The urbanization rate has been increasing steadily and rapidly from 36.22% in 2000 to 58.52% in 2017. In accordance with the fast development of Gross Domestic Production (GDP) and urbanization rate, the area of residential buildings increased dramatically. According to the data from the Nation Bureau of Statistics of China [1], the area of new residential buildings under construction per year has been increasing by 17% per year on average, compared to the year 2000 level, and reached 12.50 billion square meters in 2014 (see Figure 2). The area of new residential buildings under construction and constructed, after 2014, are leveling out around 12.5 billion square meters and
