耿翔燕, 李敏, 胡继连
Sustainable Development (SD) , 2014, DOI: 10.12677/SD.2014.44008
Abstract:
菌种的好坏直接影响食用菌的发展。山东省作为生产食用菌的第一大省，受价格体系、管理体制及政策等因素影响，在该新兴产业的管理上，特别是菌种行业的管理上尚不健全，导致菌种行业出现市场混乱、行业风险高等问题。为确保食用菌菌种行业的健康、持续发展，本文从建立信息平台、加大科研投入、促进合作建设、加强市场监管等方面提出行业管理建议，从而规范菌种市场，确保菌种质量。
The quality of strain has direct impact on the development of edible mushroom industry. Shandong Province ranks NO. 1 in production of edible mushroom nationwide. Due to the influence of price mechanism, administrative system and governing policies, defectives exist in Shandong Province’s management of the emerging edible mushroom industry, especially in sector on mushroom strain. Therefore it results in market disorders and high industry risks in the strain industry. In order to ensure healthy and sustainable development of edible mushroom strain industry, thereby regulate strain market and assure strain quality, suggestions on industry management were proposed accordingly. These suggestions focus on the following aspects: establishing information platform, increasing budget for scientific research, promoting founding of cooperatives, and enhancing market supervision.

Abstract: 共享制造是以信息技术为基础，整合并配置闲置、分散的资源以实现供需双方互利共赢的新型经济模式。本文重点研究了共享制造四种模式对于制造业高质量发展的机理与路径，研究发现，通过搭建中介型共享平台、众创型共享平台、服务型共享平台和协作型共享平台，使数字经济与制造业深度融合，促进了资源的高效利用，对制造业高端化、智能化、绿色化发展具有重要意义。但我国共享制造在数字化支撑能力、平台参与度、信息透明度、法律体系等方面还存在一系列问题，为此，我国要筑牢数字技术支撑、发挥平台的牵引作用、充分利用区块链优势、加强政策激励和法律保障。
Shared manufacturing is a new economic model based on information technology that integrates and configures idle and dispersed resources to achieve mutually beneficial cooperation between supply and demand. This paper focuses on the study of the mechanisms and paths by which the four modes of shared manufacturing promote the high-quality development of the manufacturing industry. The study found that by building intermediary-type shared platforms, crowd-creation-type shared platforms, service-type shared platforms, and cooperative-type shared platforms, the deep integration of the digital economy and manufacturing industry has been promoted, and efficient utilization of resources has been improved. This is of great significance for the high-end, intelligent, and green development of the manufacturing industry. However, there are still a series of problems in the digital support capability, platform participation, information transparency, and legal system of China’s shared manufacturing. Therefore, China needs to strengthen digital technology support, play the leading role of platforms, make full use of the advantages of blockchain technology, and strengthen policy incentives and legal protections.

Abstract: 数字经济时代，多元化战略是制造企业赋能异质性领域、拓展新增长空间的重要策略。传统多元策略以供给端为着力点实现供应商与用户之间的线性价值传递。而平台是数字经济时代价值共创的核心节点，多平台组合赋能是企业新的价值增长点，能够促进平台生态中商品提供者、互补者、最终用户等生态用户群之间的直接交互实现价值共创。基于此，本文以海尔卡奥斯平台为案例研究对象，将工业互联网平台的演化分为平台嵌入、平台聚合和平台协同三个阶段，分别对中小制造企业进行了结构赋能、数据赋能和生态赋能。研究结论能够丰富为多平台战略和组合赋能的相关研究，为数字经济背景下的制造企业依托工业互联网平台赋能中小制造企业提供借鉴意义。
In the era of digital economy, diversification strategy is an important strategy for manufacturing enterprises to enable heterogeneity and expand new growth space. The traditional multi-strategy focuses on the supply side to realize the linear value transfer between the supplier and the user. The platform is the core node of value co-creation in the era of digital economy, and the multi-platform combination enabling is a new value growth point for enterprises, which can promote the direct interaction among ecological user groups such as commodity providers, complementators and end users in the platform ecosystem to achieve value co-creation. Based on this, this paper takes the Helkaos platform as the case study object, divides the evolution of industrial Internet platform into three stages: platform embedding, platform aggregation and platform collaboration, and carries out structural empowerment, data empowerment and ecological empowerment for small and medium-sized manufacturing enterprises respectively. The research conclusions can enrich the relevant research on multi-platform strategy and combination empowerment, and provide reference for manufacturing enterprises to empower small and medium-sized manufacturing enterprises based on industrial Internet platform under the background of digital economy.

邓祥, 鲁敏, 杨燕妮, 耿琼
Hans Journal of Agricultural Sciences (HJAS) , 2025, DOI: 10.12677/hjas.2025.154048
Abstract: 本文基于昆明市烟叶主种植县(区、市)烤烟种植实际，用气候倾向变化趋势、相关性和距平分析等统计方法，首次对昆明市烟叶主种植区近63年(1961~2023年)，烤烟大田生育期(4月下旬至9月上旬)的气温和降水，分各不同生育期做气温和降水的历史演变及变化趋势分析。结果表明，昆明市烤烟主种植区气温呈显著的上升趋势变化，上升变化倾向率0.018℃/a，通过了(P > 0.01)相关性检验，降水量总体呈微减少趋势变化，变化趋势不显著，未通过(P > 0.10)相关性检验；年代降雨日数呈显著性减少趋势变化，一般性降雨日数的变化不显著，1981~1990降水日数最少。最近30多年大雨、暴雨的降水日数呈较明显增多变化，降水强度和极端性倾向突出。气温距平和K-M曲线突变交汇分析，突变出现的2007年以后，突变发生后气温上升变化显著；降水量K-M曲线出现了5次交汇，2008年后，变化显著；气温“两头低、中间高”，降水前期少，中间适当多，后期少雨的变化特征与清香云烟对气候生境的要求高度吻合。
Based on the actual tobacco cultivation in the main tobacco-growing counties (districts and cities) of Kunming City, this paper uses statistical methods such as climate tendency change trends, correlation analysis, and anomaly analysis to conduct a historical evolution and change trend analysis of temperature and precipitation during the field growth period of flue-cured tobacco (from late April to early September) in the main tobacco planting areas of Kunming City over the past 63 years (1961~2023). The results show that the temperature in the main tobacco planting areas of Kunming City has shown a significant upward trend, with an increasing trend rate of 0.018？C/a, which has passed the (P > 0.01) correlation test. The total precipitation shows a slightly decreasing trend, but the change is not significant and has not passed the (P > 0.10) correlation test. The number of days with rain has shown a significant decreasing trend, while the number of days with general rainfall has not changed significantly. The number of days with precipitation was the least during 1981~1990. In the past 30 years or so, the number of days with heavy rain and rainstorms has increased significantly, with a prominent tendency towards increased precipitation intensity and extreme weather. The anomaly analysis and K-M curve intersection analysis of temperature and precipitation show that a significant mutation occurred after 2007. After the mutation, the temperature increase was significant, and the K-M curve of precipitation intersected five times. After 2008, the change was significant. The temperature pattern of “low at both ends and high in the middle”, and the precipitation pattern of “less in the early stage, appropriate in the middle stage, and less in the late stage” are highly consistent with the climatic habitat requirements of the fragrant Yunnan tobacco.
