AbstractTo explore theadvantages and disadvantages oflayer breeding in various cities in Shanxi Province，the comprehensive comparativeadvantage index method wasadopted.By calculating the scale advantage index and effciencyadvantage index，thecomprehensivecomparativeadvantages of layerbreeding in various cities in the study area were calculated，and targeted suggestions were proposed.The results indicated that Yangquan， Xinzhou，and Datong had significant scale advantages; Jincheng，Datong，and Shuozhou had high eficiency comparative advantages; thecomprehensive comparative advantage index of Yangquan，Xinzhou，and Datong was higher; most cities had the advantage ofraising laying hens.Suggestions were putforward tocreate favorableconditions forthedevelopmentof the eggchicken industryintheregion，promote scientific breeding to improve breeding eficiency，advance the industrializationof layer breeding，and increase brand building eforts.Thisarticle provides references forpromoting the sustainable and high quality development of the layer breeding industry in the research area.

近年来，消费者对于肉食类和禽蛋类的需求与日俱增，其中肉食类产品消费以猪肉为主，禽蛋类食品消费以鸡蛋及其衍生品为主。蛋鸡养殖作为山西畜牧业经济的重要组成部分，受到越来越多的关注。相关学者对蛋鸡养殖产业及技术进行了研究。戴婧婧等对不同养殖模式下蛋鸡产蛋性能、肉品质的影响及经济效益进行分析，发现笼养模式下长顺绿壳蛋鸡的产蛋率有所上升，养殖模式和品种对蛋壳硬度的影响较大，总体上散养绿壳蛋鸡的利润空间高于笼养蛋鸡。毛锦文研究了育雏蛋鸡生产规模化养殖技术和管理措施，包括控制适宜的鸡舍温湿度、合理的饲养密度，产蛋高峰期养殖管理、蛋鸡淘汰管理，以及合理选址、封闭隔离、检测及诊断等，以提高养殖场经济效益。毕思恺等3通过对比山东省不同规模蛋鸡养殖的成本收益情况，分析该地蛋鸡养殖的适度规模，并提出完善市场价格监督机制、加强科技投入、合理控制成本、稳步发展蛋鸡规模养殖等建议。

本文以山西省大同等11个地市为研究对象，通过比较优势指数法，分析研究区各地市蛋鸡养殖的优势，从而针对性地提出相关建议，以推动该地蛋鸡养殖产业高质量发展。

1山西省各地市蛋鸡养殖现状

1.1 蛋鸡养殖条件

研究区具备较好的粮食作物生长条件，主要以小麦、玉米和小米为主，为蛋鸡饲料收购、制备提供丰富的原材料。……
