摘要

建立鼓励牧民加入合作社的机制被认为是提高生产效率的重要政策工具。本研究通过比较合作社成员（CM）和非成员（NCM）之间的技术效率（TE）、成本效率（CE）和规模效率（SE），考察了合作社是否提高了西藏省牧民的畜牧生产效率。利用两阶段DEA-Tobit模型和206名牧民的调查数据，研究评估了效率得分并确定了生产力的决定因素。结果表明，CM的TE（0.705）和SE（0.297）高于NCM(0.685、0.206和0.323)，CE（0.250）低于NCM。农牧合作效率受户主教育程度、草地面积、非畜牧业收入和技术培训等因素驱动，而农牧合作效率受年龄、普通话水平、家庭规模和经营草地质量等因素影响。调查结果强调了合作社在提高技术效率和规模效率方面的作用，但也强调了成本管理中分配效率低下的问题。政策影响包括优化投入配置，加强对合作社的技术支持，促进规模经济的草原转移，以及优先考虑教育和语言培训以缩小效率差距。

The Impact of Cooperatives on Livestock Production Efficiency in China

The development of mechanisms to encourage herders' entry into cooperatives is considered as an important policy tool to increase production efficiency. This study examines whether cooperatives increase livestock production efficiency among herders in Xizang, China, by comparing technical efficiency (TE), cost efficiency (CE), and scale efficiency (SE) between cooperative members (CM) and non-members (NCM). Utilizing a two-stage DEA-Tobit model and survey data from 206 herders, the research evaluates the efficiency scores and identifies determinants of productivity. The results reveal that CM exhibit higher TE (0.705) and SE (0.297) but lower CE (0.250) compared to those of NCM (0.685, 0.206, and 0.323), respectively. CM efficiency is driven by the education of the head of household, the area of grassland, income from non-livestock and technical training, while NCM efficiency is shaped by age, Mandarin proficiency, family size and the quality of grassland under management. The findings underline the role of cooperatives in improving technical and scale efficiency, but also highlight the allocative inefficiencies in cost management. Policy implications include optimizing input allocation, strengthening technical support for cooperatives, promoting grassland transfer for scale economies, and prioritizing education and language training to bridge the efficiency gaps.

期刊介绍： Rangeland Ecology & Management publishes all topics-including ecology, management, socioeconomic and policy-pertaining to global rangelands. The journal''s mission is to inform academics, ecosystem managers and policy makers of science-based information to promote sound rangeland stewardship. Author submissions are published in five manuscript categories: original research papers, high-profile forum topics, concept syntheses, as well as research and technical notes. Rangelands represent approximately 50% of the Earth''s land area and provision multiple ecosystem services for large human populations. This expansive and diverse land area functions as coupled human-ecological systems. Knowledge of both social and biophysical system components and their interactions represent the foundation for informed rangeland stewardship. Rangeland Ecology & Management uniquely integrates information from multiple system components to address current and pending challenges confronting global rangelands.
