Inputs, Outputs, and Total Factor Productivity in the US Farm Sector: A New State‐Level Analysis (1960–2015)
利用新方法和数据源，估算了1960至2015年美国48个州的农业投入、产出与全要素生产率，发现全要素生产率是产出增长的主要动力，但各州增速差异大，且近二十年多数州增速放缓。
We introduce new methods and data sources to generate comprehensive state‐level estimates of inputs, outputs, and total factor productivity for each of the 48 contiguous US states from 1960 to 2015. Results show that total factor productivity is the primary driver of farm output growth during the study period. However, the average annual productivity growth rates exhibit significant variation among states, ranging from 0.23% (New Mexico) to 1.95% (Ohio). While the average annual productivity growth rate has decelerated for most states over the past two decades, our test results do not indicate a consistent productivity slowdown across 10 production regions.
