摘　　要：土特产是基于资源禀赋实现价值分化的典型农产品,也是催生乡村特色产业,推动区域经济增长的重要抓手。本文以小米为例,以2006—2020年不同时空、产能、特色的11个小米主产省份为样本,采用超越对数随机前沿模型和中介效应模型,实证分析了技术效率提升对小米价值分化的影响及其作用机制。研究表明,技术效率提升对小米平均成本效益及各地区产品品质提升具有促进作用;保质机制保质机制,在论文中指小米生产者为保障产品品质不走样和信誉不下滑而采取的自我约束行为,反映出小米价值分化的内在动力与逐利机制互促作用下,技术效率提升会加剧小米价值分化;保质机制与逐利机制冲突作用下,技术效率提升对小米价值分化的影响存在空间异质性。本文认为,对于小米发展区域内的普通小米生产者,应促进技术效率的提升,提高生产能力和成本效益;对于小米成熟区域内的土特产小米生产者,应促进品牌建设和市场开拓,提高产品品质和溢价能力;对于新一轮千亿斤产能提升行动中参与的小米生产者,应促进小米“身份”分化,提升杂粮小米地位。Local specialties are typical agricultural products that realize value differentiation based on resource endowment,and are also an important starting point for promoting rural characteristic industries and regional economic growth.Taking millet as an example,this paper takes 11 major millet producing provinces with different time and space,production capacity and characteristics from 2006 to 2020 as samples,and adopts the translogarithmic stochastic frontier model and the intermediate effect model to empirically analyze the influence of technological efficiency improvement on millet value differentiation and its mechanism.The research shows that the improvement of technical efficiency has a promoting effect on the average cost efficiency of millet and the improvement of product quality in various regions;Under the mutual reinforcement of quality preservation mechanism and profit-seeking mechanism,the improvement of technical efficiency will exacerbate the value differentiation of millet;Under the conflict between quality preservation mechanism and profit-seeking mechanism,the influence of technological efficiency improvement on the value dfferentiation of millet has spatial heterogeneity.The paper holds that technical efficiency should be enhanced so as to improve production capacity and cost effectiveness for general millet producers in the development regions of millet,while brands-building and market-developing should be promoted for specialty millet producers in the mature regions of millet so as to improve the quality and premium pricing of millet.It is suggested to promote the differentiation of millet identity and its role in coarse cereals for millet producers in the new round of grain production increase by 50 billion kilograms.
