Urbanization and the industrialization of agriculture
研究了城市化对周边农场规模和退出模式的影响，发现城市压力导致小农场缩小或退出，而大农场则扩大规模，从而推动农业产业化。
Abstract As urban environments expand, urban pressure is likely to generate increased competition for resources used in the agricultural sector, such as land and labor. We assess the effects of this urban pressure on the size and exit patterns for local farms. Our results suggest that the effects of urbanization on nearby farms are fundamentally heterogeneous. Increasing urban pressure causes smaller farms in neighboring areas to downsize or exit the industry, whereas large farms scale up in the face of growing urban pressures. In other words, local competition for resources as a result of urbanization can serve as an important mechanism for agricultural industrialization.
