A SIMULTANEOUS EQUATIONS MODEL OF MIGRATION AND ECONOMIC CHANGE IN NONMETROPOLITAN AREAS*
利用美国1960-1970年数据，建立联立方程模型分析非都市地区迁移、就业增长与收入增长的关系，发现经济与人口变化模式存在明确关联，但与都市地区有重要差异。
A simultaneous equations model of migration and economic growth in nonmetropolitan regions of the United States is estimated using data for 1960-1970. The dependent variables considered include in-migration, out-migration, growth in employment, and growth in income. The findings indicate that there is a definite link between the patterns of economic and demographic change in nonmetropolitan areas but that it differs in important respects from that which has been observed in metropolitan areas.
