英文文献摘要：
This study aims to understand the relationship between regional growth in population, employment, and per capita income, and agricultural land values and development in the Northeast United States. A system of spatial simultaneous equations is estimated using three-stage-least squares on county level data. Results indicate that regional growth positively influences agricultural land values and negatively affects the stock of agricultural lands. Farm performance and some farmland protection policies were not effective in preserving farmland. The study recommends that agricultural land protection policies could be better coordinated at a regional level and more effective if integrated within state economic development programs.
本研究旨在了解美国东北部地区人口、就业和人均收入的区域增长与农业用地价值和发展之间的关系。一个空间联立方程组系统估计使用三级最小二乘在县级数据。结果表明，区域经济增长对农用地价值产生正向影响，对农用地存量产生负向影响。农业绩效和部分耕地保护政策对保护耕地效果不佳。该研究建议，农业土地保护政策可以在区域一级更好地协调，如果与国家经济发展计划相结合，则会更有效。
