Environmental protection and economic growth are two indicators of sustainable global development. This study aims to investigate the performance of environmental protection and economic growth by measuring carbon productivity in the construction field. Carbon productivity is the amount of gross domestic product generated by the unit of carbon emissions. The log mean Divisia index method is used to investigate influential factors including carbon intensity, energy intensity and regional adjustment that impact on changes of carbon productivity. The study utilises a range of data from the Australian construction industry during 1995-2004 including energy consumption, industry value added and carbon dioxide equivalent consumption. The research indicates carbon productivity in the Australian construction industry has clearly increased. Energy intensity plays a significant positive role in promoting carbon productivity, whereas carbon intensity and regional adjustment have limited influence. Introducing advanced construction machinery and equipment is a feasible pathway to enhance carbon productivity. The research method is generic and can be used to measure other performance indicators and decomposing them into influential factors.

澳大利亚建筑业基于对数均数指数的碳生产率

环境保护和经济增长是全球可持续发展的两个指标。本研究旨在通过测量建筑领域的碳生产率来研究环境保护和经济增长的表现。碳生产率是单位碳排放量产生的国内生产总值。对数均值Divisia指数法用于研究影响碳生产率变化的影响因素，包括碳强度，能源强度和区域调整。该研究利用了澳大利亚建筑业在1995-2004年期间的一系列数据，包括能源消耗，工业增加值和二氧化碳当量消耗。研究表明，澳大利亚建筑业的碳生产率已明显提高。能源强度在促进碳生产率中起着重要的积极作用，而碳强度和区域调整的影响有限。引进先进的建筑机械和设备是提高碳生产率的可行途径。该研究方法是通用的，可用于衡量其他绩效指标并将其分解为影响因素。
