Comparison of Global Fisheries' Efficiency Levels Using Meta-frontier

The common meta-frontier method was conducted to compare the fisheries efficiency level across continents and/or regions. Technical efficiency (TE), meta-frontier, and technical gap ratios (TGR) were calculated to show the distance estimation from an input-output point of the frontier. Also, the distance between the regional frontier and meta-frontier was estimated to calculate TGR. This study points out regions that the fishing effort level will reach critical levels in upcoming decades. In order to examine this issue, we conducted a comparison of six fishery regions, based on countries from which sufficient data were available to analyze the efficiency using the meta-frontier method.
