深圳市施工人员建筑废弃物减量化行为趋势研究

为比较分析施工人员减量化行为的转变，论证《深圳市建筑废弃物减排与利用条例》对施工人员减量化行为的影响，结合Ajzen 的计划行为理论设计了施工人员的建筑废弃物减量化行为意识量表，并于2009 年和2013 年对深圳市施工企业人员展开了两次调查。调查结果表明:该条例颁布实施后，施工人员减量化行为频率提高幅度为16.7%；减量化行为的改善主要是由知觉行为控制力提升引起的；施工人员是否实施减量化行为主要取决于他们是否愿意实施减量化行为。建议政府制定强制性的减量化行为实施细则，明确建设单位和施工单位的减量化目标，以提升施工人员感知到的社会压力，进而促进施工人员的减量化行为。
