THE INFLUENCE OF ECONOMIC DIVERSITY ON UNEMPLOYMENT AND STABILITY*
研究了美国大都市区经济多样性对失业率和就业稳定性的影响，发现多样性越高的地区失业率越低、就业越稳定。
ABSTRACT. For many years, regional scientists, economists, and geographers have been unable to clarify the influence of economic diversity on unemployment and instability in regional economies of the United States, the United Kingdom, and Canada. This article presents plausible theory, proper units of analysis, valid measures, and more inclusive models of the diversity‐stability relationship. The findings are generalizable because the sample includes most metropolitan areas in the U.S. The empirical analysis estimates the influence of diversity, employment concentrated in unstable industries, population size, growth rate, and control variables on unemployment and employment instability during the 1972–88 period. The results indicate that metropolitan areas which are more diverse experience lower unemployment rates and less instability than areas which are less diverse.
