The energy conservation has become a considerable issue in construction industry for achieving sustainable development. Therefore it is crucial for policy-makers to look for optimized and flexible tools to measure the total energy consumption efficiency in construction industry. Data envelopment analysis (DEA) can be applied for multiple input and output decision-making units (DMUs) productivity measurement. DEA-based Malmquist productivity index (MPI) can be used as a tool for measuring the productivity change longitudinally. In this paper, we use input-oriented model to measure the energy consumption productivity change of the construction industry from 2004 to 2009 with data in 26 provinces of China. It is found that only Guangdong demonstrated effective energy improving in the whole reference period. It also identified the regional groups always lie on the efficiency frontier of energy consumption as benchmarks. Regional analysis shows that energy conservation gaps exist between northeastern, western region and central, eastern region. DEA-based Malmquist productivity index provides a good way to measure the energy consumption efficiency and can help policy-makers to improve strategies of sustainable development in China. © 2014 Elsevier Ltd.

The construction industry has been recognized for its conservatism and lack of innovation. In order to improve the success rate of construction innovation, the implementation of innovations within the context of construction has been discussed and developed. Literature in this area focuses extensively on construction innovation, and yet does not contain a systematic review. This paper looks to fill this gap by providing a systematic review of construction innovation. The review synthesizes the conclusions and shows the implementation of construction innovation. Collaboration, culture, innovation process, and drivers are identified as critical factors to improve the performance of construction innovation. Finally, the limitations of prior studies in construction innovation are discussed and recommendations made for areas of future study.
