THE DISTRIBUTION OF SERVICE ESTABLISHMENTS*
研究发现服务设施密度与人口密度的2/3次幂成正比这一预期不成立，并基于时间最小化理论重新推导以解释新发现。
ABSTRACT All previous theory and research have led to the expectation that the density of service establishments will be proportional to the 2/3 power of the density of the population served by them. Study of the distribution of over 400 nongovernmental establishments refutes this expectation for such cases. A previous derivation from time minimization theory is reformulated to encompass these new findings.
