摘要：We present a bioeconomic model of a harvesting industry operating over a heterogeneous environmentcomprised of discrete biological populations interconnected by dispersal processes. The modelgeneralizes the H. S. Gordon [1954]/V. Smith [1968] model of open-access rent dissipation by accountingfor intertemporal and spatial "Ricardian" patterns of exploitation. This model yields a simple, butinsightful, framework from which one can investigate factors that contribute to the evolution of resourceexploitation patterns over space and time. For example, we find that exploitation patterns are driven bybiological and fleet dispersal and biological and economic heterogeneity. We conclude that one cannotreally understand the biological processes operating in an exploited system without knowing as muchabout the harvesting system as about the biological system.
