We studied the efficiency and productivity of BC’s secondary wood manufacturing sector using Data Envelopment Analysis (DEA) and Malmquist total factor productivity index (MPI), while incorporating data from both a survey on individual firms and Statistics Canada’s sectoral data. DEA results showed that BC’s secondary wood manufacturing firms had low efficiency and the factor contributing to the inefficiency was more lack of technical capability than scale of operations in most of the business types. The MPI results reveal that SWM consistently underperforms relative to the sawmill and panel sectors, with a clear divergence emerging after the 2007–2009 financial crisis. Weak productivity growth is largely attributable to limited and inconsistent technical change, reflecting a lack of innovation and adoption of new technologies. Policies aimed at supporting the sector could focus on factors improving firms’ technical efficiency and frontier such as process optimization, technology adoption and innovation, and training and skill development.
