Land Quality Perceptions in Expert Opinion Surveys: Evidence from Iowa
利用2015年爱荷华州土地价值调查数据，研究受访者如何感知土地质量，发现农业专业人士对土地质量的感知具有区域特异性，高、中、低质量应基于当地作物报告区进行解释。
While many opinion-based surveys ask land values for different land quality classes, little is known how survey respondents perceive the land quality. Using the 2015 Iowa Land Value Survey, this article examines how respondents perceive land quality in their responses to land value questions. Our results show agricultural professionals seem to perceive land quality with respect to specific regions, and high, medium and low land quality should be interpreted locally within a crop reporting district. This case study suggests that it is difficult to generalize uniform yield or soil productivity index ranges for land quality questions in all opinion-based surveys.
