The Roepke Lecture in Economic Geography Location Theory, Location-Allocation Models, and Service Development Planning in the Third World
指出农村地区缺乏综合服务体系是欠发达的原因，提出区位分配分析系统可诊断服务可及性问题、评估区位决策效率，并生成可行方案，但需在更广泛的区位理论框架中应用以实现发展目标。
The absence of an integrated system of settlements providing services and facilities is often cited as a cause of underdevelopment in rural areas. Location-allocation analysis systems provide an explicit framework for diagnosing service accessibility problems, measuring the efficiency of recent locational decisions and the current levels of settlement efficiency, and generating viable alternatives for action by decision makers. Development objectives are realized only when these models are applied within a broader location theory framework in which the often antagonistic behaviors of the many actors are recognized.
