全球水产养殖看中国。随着捕捞资源日趋紧张，全球水产养殖的大发展始于20世纪90 年代。亚洲占全球水产养殖总量的92%，中国占全球水产养殖总量的接近60%，欧美地区水产养殖的全球占比较小。中国鱼类和虾蟹类养殖量分别占全球50%和55%，遥遥领先于全球其他地区。

Aquaculture includes farming of fish, aquatic plants, algae, crustaceans, molluscs, and other organisms. Small-scale aquaculture market in developed and developing countries make critical contributions to employment. According to the FAO, aquaculture provides employment to more than over 41 million people globally. The vast majority of aquaculture activities are carried out in developing countries working in fish production. Fish and other seafood species constituting an important source of nutrients for the poor and is among the cheapest form of animal protein. As most capture fisheries worldwide considered fully exploited or overexploited, aquaculture is considered as an important sector to meet rising fish demand, which will continue to increase with population growth, rising incomes and increasing urbanization. The aquaculture sector in North America is dominated by finfish and trout, primarily channel catfish in the US of America, Atlantic salmon in Canada. A smaller segment is dedicated to the production of bivalve molluscs shellfish, mainly a number of species of oysters, mussels, and clams. The availability of suitable environment, technology, and financing for the aquaculture industry in this region boost the aquaculture market growth. Rising demand for aquaculture-produced seafood, coupled with increased consumer demand for seafood in the diets of people is expected to propel the aquaculture market in North America. In North America, health benefits of cultured seafood are routinely promoted as part of marketing, and FAO described both Canadian and American government initiatives for promoting the consumption of seafood which propels the demand for seafood in this region

我们认为，压制园林行业估值的因素已出现边际改善。现金流方面，目前工程企业正进行订单结构的调整，加速向现金流较好的EPC 业务进行转型，审慎承接订单，严格审核订单所处区域、回报率、回款等条件，预期今年企业的现金流将继续大幅度改善。融资环境方面，随着疫情的发酵，政策对民企的支持力度加大，今年行业的融资成本大概率将下行，尤其是拟将控制权转让给国资的园林企业，融资成本的下降将尤为显著。行业项目质量层面，随着专项债大幅向生态领域倾斜，整体项目的质量和回款将得到边际改善。因此，行业尽管短期仍然缺乏估值大幅提升的催化剂和拐点，但趋势估值持续下降的要素已发生转变。

医药生物和农林牧渔跑赢沪深300 指数。周三大盘持续上涨。大消费板块中，仅医药生物和农林牧渔跑赢沪深300 指数，其他消费行业均跑输沪深300 指数。其中医药生物行业走势回归理性，医药龙头稳步上涨。

国内外同时减产，奠定价格抬升基础。根据中糖协最新预测，2019/20榨季全国食糖产量预计1062 万吨左右，考虑到进口约300 万吨左右，走私打击力度趋严，我们预计走私量在100 万吨以下，因此总供给在1450 万吨左右。而食糖消费相对稳定在1500 万吨左右，新榨季国内供给较为紧张。同时印度、泰国等主产国进入减产周期，巴西维持低位，国际糖业格局改善，将助力国内价格上涨。

新冠肺炎疫情影响散户补栏、饲料调运，产能恢复节奏被打乱。由于防控措施产生的禁运，部分散养户出现饲料短缺、仔猪补栏困难等情况。根据青松农牧的调研数据，当前散养户中补栏受到影响的占比78%；饲料储备上，只能够维持1 周之内生产经营的养殖户占比约56%；生猪销售方面，未受影响的养殖户占比仅约11%。1月30 日，农业农村部召开会议强调加强“菜篮子”产品生产保供，推动解决畜禽水产养殖饲料补充、“菜篮子”产品外运方面存在的问题；2 月4 日，农业农村部发布关于维护畜牧业正常产销秩序、保障肉蛋奶市场供应的紧急通知。若后续政策逐步落地，饲料短缺、仔猪补栏等困难才能逐步得到缓解。

受肺炎疫情下，养殖场原料供应、补栏都受到了不同程度的影响，但是开盘第一周，生猪养殖板块却走势强劲。我们认为疫情对短期供需造成一定的影响，但是板块整体的投资逻辑没有改变，本文重点论述两个问题：（1）当前行业补栏情况如何，怎么看后续产能变化（2）2020 年养猪股投资核心逻辑。

磷肥属于少数产能持续收缩的化工行业之一，而需求相对稳定，磷肥行业经过几年调整有望重新进入新的上行周期。
