Effect of Bt traits on transgenic rice's growth and weed competitiveness

Transgene escape could lead to genetically modified rice establishing wild populations in the natural environment and competing for survival space with weeds.However,whether the expression of the Bacillus thuringiensis(Bt)gene in rice will alter the relationship between transgene plants and weeds and induce undesirable environmental consequences are poorly understood.Thus,field experiments were conducted to investigate the weed competitiveness and assess the ecological risk of transgenic Bt rice under herbicide-free and lepidopterous pest-controlled environments.Results showed that weed–rice competition in the direct-sowing(DS)field was earlier and more severe than that in the transplanting(TP)field,which resulted in a significant decrease in biomass and yield in DS.However,conventional Bt and non-Bt rice yield was not significantly different.The weed number,weed coverage ratio,and weed diversity of conventional Bt rice were significantly higher than those of non-Bt rice at the early growth and mature stages,especially in DS plots,suggesting that Bt traits did not increase the weed competitiveness of transgenic rice and had no negative effect on weed diversity.Grain yield and weed number varied between different hybrid rice lines,but those differences were insignificant between Bt and non-Bt rice.The number of insects increased with the increase of weeds in hybrid rice plots,whereas the insect number and diversity did not display a significant difference between Bt and non-Bt rice.Therefore,the ecological risk of transgenic Bt rice is comparable to non-Bt rice.

美对华半导体管制的趋势、实施要点与中国因应

针对不断升级的中美半导体领域争端,本文梳理了美国对华半导体管制的趋势与要点。从特朗普政府到拜登政府,美对华半导体管制呈现出由“有限出口”向“全面出口管制”、由“5G”延伸至“AI”、由“大棒”扩展为“胡萝卜加大棒”、从“单边约束”扩展到“多边合围”的趋势。从管制要点来看,拜登政府在半导体产业链的所有关键环节都设计了阻碍中国技术进步的方案,不但限制高算力芯片成品对华出口,而且限制产业链上游的芯片制造设备、零部件、芯片设计软件出口以及产业链下游的算力租赁服务。针对美政府全方位围堵,本文提出对外强化与非热点半导体国家的联系、重视非传统技术路线半导体开发、借鉴比利时微电子研究中心运作模式发展共性技术机构等产业突围思路。

数据不正当竞争行为判定的反思与完善

准确判定数据不正当竞争行为是规制该类行为的关键。实证考察2012-2023年的数据不正当竞争案件裁判文书后发现,对数据不正当竞争行为判定,普遍适用权益侵害判定范式,这误读了反不正当竞争法的法律属性;对竞争关系的认定存在拓宽化的倾向,其在数字时代反不正当竞争法适用中的现实价值和改进进路尚待厘清;既有的以“搭便车”原则、互联网行业惯例和法官创制性细则为标准具体化商业道德的进路皆无法化解商业道德的不确定性难题。对此,为促进数据健康有序流动,维护数字市场的竞争秩序,应实现数据不正当竞争行为判定路径的“系统性”变革。首先,应实现权益侵害判定范式向行为正当判定范式的有效转变,确保法院裁判结果符合反不正当竞争法的法益保护目标和契合数字经济发展的需求;其次,纠正“竞争关系决定论”的误区,调整竞争关系在数据不正当竞争案件中的角色定位,将其作为认定原告资格的重要标准和评测损害程度的因素;最后,认定商业道德应兼顾公平竞争价值与自由竞争价值,遵循“由事实到价值”的商业道德内涵的确定步骤,肯定模仿自由并慎用“搭便车”裁判标准,并且在援引互联网行业惯例时应对其是否符合法律法规和有助于维护竞争秩序予以考察,应让创设的商业道德具体细则符合反不正当竞争法的价值目标。
