THE DETERMINANTS OF 1963–77 REGIONAL MANUFACTURING GROWTH: WHY THE SOUTH AND WEST GROW*
分析了美国48个州1963-77年制造业就业增长，发现市场、气候、农村吸引力等六因素解释了96%的差异，而阳光带-霜冻带二分法不成立。
ABSTRACT. This paper analyzes 1963–77 manufacturing employment growth in the 48 contiguous states. Six factors jointly explain 96 percent of the variance. Markets explains 55 percent; climate, 15 percent; a rural state attraction, 11 percent; unionization, 6 percent; thresholds, 5 percent; and amenities, 4 percent. Resources, taxes, and business climate lack significance. Sunbelt‐Frostbelt is a false dichotomy: the Northwest grew as fast as the South. The real contrast–largely caused by markets–is between growth rates of 6 percent in the Manufacturing Belt, 35 percent in its bordering Transition Zone, and 58 percent in the combined South and West.
