The advancement of the intelligent manufacturing industry(IMI) represents the future direction for the world's manufacturing sector, offering a promising avenue to bolster national competitiveness and enhance industrial manufacturing efficiency. In this study, we took the industrial robot industry(IRI) as a case study to elucidate the spatial distribution and interconnections of IMI from a geographical perspective, and the modified diamond model(DM) was used to analyze the influencing factors. Results show that: 1) the spatial pattern of IRI with various investment attributes in different industrial chain links is generally similar, centered in the *** investment areas are in the east and south. The spatial distribution of China's IRI covers a multitude of provinces and obtains different scales of investment in different countries(regions). 2) The spatial correlation between foreign investors and China's provinciallevel administrative regions(PARs) forms a network, and the network of foreign-invested enterprises is more stable. Different countries(regions) have distinct location preferences in China, with significant spatial differences in correlation degrees. 3) Overall, the interaction of these factors shapes the location decisions and correlation patterns of industrial robot enterprises. This study not only contributes to our theoretical knowledge of the industrial spatial structure and industrial economy but also offers valuable references and suggestions for national IMI planning and relevant industry investors.

在平台时代,政府搭台如火如荼。但政府如何为社会治理搭建多边平台,学界则缺乏针对性研究。为此基于多边平台理论,通过对社区社工服务中心的跨案例研究,归纳政府搭建多边公共平台的机理与进路。治权开放是政府搭台的前提,设置创价关卡并赋权释能是搭建平台的基础,召集多边用户并形成互动合作的价值网络是政府搭台的关键。提供平台基础设施往往是政府搭台的必选关卡,激发网络效应是吸引用户进驻平台的重要策略,平台思维直接影响政府搭台的路径选择。政府有责任为社会治理搭建多边平台,履行着提供基本要素、召集多边用户、授予治理权力、安排治理规则等职责。

平台革命时代与平台经济社会孕育政府平台组织建设,多边平台已成为一种新的组织范式,而既有研究缺乏多边平台概念基础和平台组织学的分析视角。考察界定平台性政府概念及边界,对于科学认识其学理定位、避免建设偏误,进而推进政府理论创新与治理现代化尤为重要。平台性政府是匹配平台经济基础、推行平台型治理的政府组织模式,以多边平台业务主办方和多边平台载体承办方的组织身份出现,表现为“科层为体、平台为用”的嵌套结构,按照“政府多边平台+不同价值创造主体”的模式运作,实际上是一种基于价值网络的生态互动型组织。平台性政府是对科层制政府的突破与局部替代,与科层制政府对立共生且优势互补。平台组织属性推动互动共治,支撑公民主权与政绩合法,而科层制底座确保秩序可控,维系政府主政与政治合法。平台性政府以数字平台为依托和建设突破口,重塑治理结构、权责体系与组织模式,以突破数字平台的技术理性和单一面向。平台性政府与平台型治理在互生中交融,是治权开放基础上公共品多元供给、协作创新与公共事务参与合作的治理模式。

为研究淮河流域水稻、小麦、玉米三大谷类粮食作物生产用水总量和用水效率,保障粮食安全,促进粮食生产可持续发展,本研究以淮河及沂-沭-泗水系的35个地级市为研究对象,基于2000-2019年谷物生产、水资源、气候等数据,采用PenmanMonteith模型、探索性空间数据分析(ESDA)模型、空间杜宾模型,对流域谷物生产水足迹强度进行测度以反映其用水效率,并分析其时空演变特征及影响因素。结果表明,2000-2019年淮河流域谷物生产水足迹逐渐趋于稳定,谷物生产水足迹强度整体下降82.86%。水足迹强度空间集聚显著,集聚状态逐渐稳定。社会经济条件、农业生产投入、农业生产条件、自然条件与资源禀赋对谷物生产水足迹强度影响显著。淮河流域谷物生产用水总量整体增加,用水效率总体不断提升。淮河流域谷物生产用水效率存在显著的空间差异,效率较高的区域为淮河干流下游及沂-沭-泗水系,效率较低的区域为淮河干流安徽段。农村经济发展水平、科技发展水平与有效灌溉面积等因素的提升能促进谷物生产用水效率的提升,城镇化水平、化肥施用量、年日照时长、年平均气温等因素的提升则会对其产生抑制作用,农村经济发展水平、城镇化水平、年平均气温等因素通过要素流动、技术转移等产生空间溢出效应。

针对基于瞬时无功理论的ip-iq谐波检测法结构复杂、响应速度慢等问题,提出了一种采用改进正弦幅值积分器结构的谐波电流检测方法。首先,利用二阶广义积分器的输出滤波特性及正弦幅值积分器的极性选择特性,使其相结合构造出了一种滤波性能更强,同时具有频率及极性选择作用的新型积分器。然后,利用该积分器快速准确地提取基波正序分量,并有效应用于谐波检测环节中。当电网电压存在直流偏置问题时,该积分器所构造的锁相环也能准确锁定电网频率及相位信息。最后,理论分析及仿真实验结果表明:该方法无需进行瞬时对称分量分离,就可提取出电网电压及负载电流基波的正负序分量,计算量小,谐波检测更精确。
