在百年未有之大变局下,人类正在迎来以数字技术为代表的新一轮科技革命和产业变革,形成以数字基础、数字政府、数字社会、数字经济、数字能力为内容的数字生态。数字生态不断催生新技术、新产业和新动能,促进新质生产力发展,推动新质生产关系形成。当前,我国农业正面临着传统与现代并存二元结构转型升级关键期,必须充分发挥数字技术破解农业迂回生产分工难和产业组织集聚难的作用,以数字生态及与之相适配的制度组态推动农业新质生产力衍生与发展。基于此,以全国统一大市场建设为契机,运用生产力与生产关系的辩证关系原理,构建制度组态、数字生态与农业新质生产力培育的理论机制,综合运用必要条件分析法与动态定性比较分析法,利用我国30个省份(不包括西藏和港澳台地区)2019—2022年面板数据进行案例分析。定性比较分析法的单个必要性分析表明,数字生态要素的有效协同是培育高农业新质生产力的必要条件;必要条件分析表明,低数字能力与低数字经济制约农业新质生产力的培育;定性比较分析的条件组态充分性分析表明,培育农业新质生产力必须依靠数字生态要素及其匹配制度要素的有效组合,实施政府主导型、政府-市场双轮驱动型和政府-市场-社会三轮驱动型的组态路径。进一步加快农业新质生产力发展,应充分发挥全国统一大市场建设的数字化赋能作用,因地制宜选择农业新质生产力培育的组态路径,着力推动工业颠覆性技术在农业领域的广泛应用,大力加强农业数字化与数字化农业创新能力建设,全面深化以新质生产关系为导向的农业体制改革。

Mississippi Valley-type(MVT) Zn-Pb deposits predominantly form within both orogenic forelands and fold-andthrust belts, yet the mineralization process within the latter tectonic setting remains inadequately understood. This study, through a comprehensive review of MVT deposits across global fold-and-thrust belts, introduces a novel model elucidating the mineralization process in the context of tectonic belt evolution. It is demonstrated that during the stage Ⅰ, regional compression is introduced by early stages of plate convergence, causing the folding and thrusting and creating structural or lithological traps such as evaporite diapirs and unconformity-related carbonate dissolution-collapse structures. Thereafter, in stage Ⅱ, hydrocarbons begin to migrate and accumulate within these traps, where reduced sulfur is generated through thermochemical or bacterial sulfate reduction concurrent with or preceding Zn-Pb mineralization. In the subsequent stage Ⅲ, as plate convergence persists, the regional stress transitions from compression to transpression or extension. Under these conditions, steeply-dipping extensional faults are generated, facilitating the ascent of metalliferous brines into early-formed structural or lithological traps. Precipitation of Zn and Pb sulfides occurs through the mixing of Zn-Pb-transporting fluids with pre-existing reduced sulfur or by interaction with hydrocarbons.
