Research on Agricultural Production Efficiency of Lanzhou-Xi’ning Urban Agglomeration

Abstract

To clarify the efficiency and spatial-temporal characteristics of regional agricultural production is of great significance for adjusting the structure of agricultural production, improving the mode of agricultural production and coordinating the relationship between industries development. Based on the spatial constraints of the main function division, taking the counties providing agriculture products in Lanxi urban agglomeration as the basic research unit, using DEA model, we analyze the spatial-temporal characteristics, dynamic trends and the total factor productivity of the agricultural production efficiency from 2000 to 2015. The results showed that: 1. The overall agricultural efficiency of Lanxi urban agglomeration was very low and a few of regions were in the productive frontier, agricultural scale efficiency was greater than pure technical efficiency. 2. The spatial characteristics of the overall efficiency was “middle collapse”, while the pure technical efficiency and scale efficiency presented a gradient distribution pattern. The provincial differences showed that the overall agricultural efficiency and pure technical efficiency of Gansu Province were relatively high, while the opposite is true in Qinghai Province. 3. The overall TFP of agriculture was on the rise, and the overall efficiency improvement was shifted from the improvement of pure technical efficiency to the increase of scale efficiency. The TFP and its decomposition indicated that technological progress is the most important factor, which drives the rise of agricultural total factor productivity.
