A Logistic equation gray prediction model was established for prediction of reuse and reclamation rate of urban sewage in *** on the data of reuse and reclamation of urban sewage in Ningxia in 2006-2013,it analyzed and predicted the development trend of reuse and reclamation of urban sewage in the whole region of Ningxia. The prediction results indicate that: according to the current development trend,the reuse and reclamation rate of the whole region of Ningxia has become close to saturation,the development space is limited,there is a huge gap with the planned objectives,thus it is required to actively adjust the development strategies. On this basis,the main limiting factors affecting the reuse and reclamation of urban sewage in Ningxia were determined by analytic hierarchy process( AHP) method,in order to provide a reference for the rapid development of reuse and reclamation of urban sewage in Ningxia.

Based on water resources conditions,social development,social economy and ecological conditions,the Indicators system for sustainability assessment of water resources use( ISSAWRU) was established for Yinchuan City. Using the Technique for Order of Preference by Similarity to Ideal Solution( TOPSIS),the sustainable development and utilization plan of water resources was assessed for Yinchuan City during 2010-2014. In 2010-2014,there were no significant changes in the natural conditions of water resources in Yinchuan City; however,with the promulgation of national water resources related policies,Yinchuan City realized gradual increase in the water resources utilization rate,gradual improvement in the ecological environment,and gradual optimization of water resources sustainable utilization situation at the same time of ensuring rapid economic growth.

本文希望通过对B市业主维权实践进行描述和分析,回答业主维权为何呈现多样化的发展轨迹,以及这种维权轨迹中法律与社会的关系如何这两个问题。笔者认为:在中国转型社会背景下,由于缺乏相应的社会空间,法律呈现出"维权武器"与"维权瓶颈"并存的二重属性,法律二重性的张力推动维权从"组织、制度、身份"三个维度向社会行动扩展,扩展中的社会行动重建了"法律与社会"的关系并推动着公民社会的生长。

新常态下,大数据产业被定位为重要的战略性新兴产业,协同创新则被视为其产业驱动力。但学界对协同创新的理论含义与现实运作还缺乏关注。基于A市海上丝绸之路大数据平台建设这一经验案例,可以描摹作为网络过程的协同创新平台的构建与运行。协同创新看似是由政府、高校和企业三方合作形成的正式组织网络,但其依托的实为参与主体之间的人际网络。人际联系与组织联系两者相互转换,将各主体自身的利益打包进协同创新活动,在互动博弈中摸索出共同利益和创新目标。“牌子”是网络生成与变化的关键机制。作为政府认可的正式资格,“牌子”指向非封闭且高度模糊的创新活动,暗含多层次的资本空间,因此流动于政界、业界与学界,具有“组织身份”“资源信号”“合法性依据”“利益孵化器”四个面相。通过策略性地获取和运用“牌子”,协同创新网络不断延展,形成了跨越条块与层级的不断变动的网络结构,加剧了创新活动的不确定性。这种不确定性和大数据作为战略性新兴产业的特性相互呼应,在一定程度上加深了大数据产业的创新困境。
