Agricultural Land Values under Urbanizing Influences
结合农业和城市边缘模型，利用普查数据估计西弗吉尼亚州农田价格方程，发现农业收入和城市影响共同决定土地价值，并验证了引力模型在捕捉城市影响方面的有效性。
The research reported in this paper combines agricultural and urban-fringe models, utilizes a combination of cross-sectional and time-series data from the Census of Agriculture and other sources, and estimates a single-equation model for West Virginia farmland prices. Urban influences on land prices are captured using a gravity model adapted from marketing research. The results indicate that both farm income and urban influences have been important factors affecting the value of the state's farmland. The gravity model is a promising and parsimonious method for capturing urban influences in a single variable that combines size and distance.
