High-quality development level evaluation and path selection of prefabricated buildings

For a long time,Chinese construction industry has had disadvantages such as waste of resources,environmental pollution,long construction period,great influence by weather,low enterprise efficiency and poor benefit.While being able to solve the disadvantages of traditional buildings,prefabricated buildings,as an important starting point to achieve the carbon peaking and carbon neutrality goals,are far superior to traditional buildings in green and low-carbon,energy conservation and emission reduction,which can accelerate the transformation and upgrading of the construction industry.In recent years,the government has vigorously promoted prefabricated buildings,but the implementation of prefabricated buildings has been frequently hindered and the development of prefabricated buildings in China has not achieve the expected goal in many aspects.Under the high-quality development strategy proposed by the central government,how to promote the high-quality development of prefabricated buildings in China is one of the key difficulties of Chinese construction industry in the future.Therefore,it is necessary to proceed from the connotation of the high-quality development of prefabricated buildings,establish an evaluation model for the high-quality development level of prefabricated buildings through AHP and comprehensive fuzzy evaluation to master the high-quality development level of prefabricated buildings in China,and explore the reasonable paths selection forthe high-quality development of prefabricated buildings in China.

“Extreme utilization”development theory of unconventional natural gas

In the process of unconventional natural gas development practice,the"extreme utilization"concept that focuses on"continuously breaking through the limit of development technology"is gradually formed,and supports the scale benefit exploration of unconventional gas in China.On this basis,the development theory of"extreme utilization"is proposed,its theoretical connotation together with development technologies of unconventional natural gas are clarified.The theoretical connotation is that,aiming at"extreme gas reservoirs","extreme techniques"are utilized to build subsurface connected bodies,expand the discharge area,and enlarge the production range,to obtain the maximum single-well production,extreme recovery,and eventually achieve the"extreme effect"of production.The series of development technologies include micro/nano-scale reservoir evaluation,"sweet spot"prediction,unconventional percolation theory and production capacity evaluation,optimization of grid well pattern,optimal-fast drilling and volume fracturing,and working regulation optimization and"integrated"organizing system.The"extreme utilization"development theory has been successfully applied in the development of unconventional gas reservoirs such as Sulige tight gas,South Sichuan shale gas,and Qinshui coalbed methane.Such practices demonstrate that,the"extreme utilization"development theory has effectively promoted the development of unconventional gas industry in China,and can provide theoretical guidance for effective development of other potential unconventional and difficult-to-recovery resources.

Regional Evaluation on Sustainable Development of Agriculture in Tibet Based on Cluster Analysis

To understand the spatial difference of agricultural sustainability in Tibet,this paper establishes a comprehensive evaluation model of agricultural sustainability to calculate the score of agricultural sustainability of 7 areas in 2013 in Tibet. By using cluster analysis,this paper conducts the regional evaluation of Tibet's agricultural sustainability. The results show that 7 cities' regional difference of agricultural sustainability was obvious in 2013,the agricultural sustainability index value was 0. 4232- 0. 6937,and the value was in the order of Nyingchi > Lhasa > Shannan > Ali > Shigatse > Qamdo > Nagqu.

陕西省农民全面发展的评价指标体系构建及其测度研究

农民全面发展水平决定着乡村振兴的实施进程。基于陕西省2010—2022年的统计数据,从马克思人的全面发展理论出发,运用熵值法和层次分析法从需要、活动能力、社会交往、自由个性4个维度构建指标体系,并对陕西省农民全面发展的水平、变化趋势和耦合协调度进行分析。结果表明:陕西省农民全面发展受到发展型消费占比、从农意愿等因素的深刻影响,目前处于初步上升阶段,发展趋势和耦合协调度较好,但发展稳定性和抵御风险的能力需要进一步提升。4个维度的发展均呈现波动上升趋势,其中,需要的发展水平最好,活动能力发展最为平稳,自由个性发展波动最大,存在发展能力和发展意识不够稳定的情况。针对上述问题,从优化农民教育培训模式、持续发挥政府保障作用、激发农民自我发展意识三个方面提出对策建议。

一种新的基于时序增益激励的赋权方法及应用

针对具有激励特征的动态综合评价问题,在分层规则和激励导向的基础上,提出一种具有识别功能的时序增益激励赋权方法。首先根据各被评价对象在各指标上的整体增益速度的趋势和状态,遵照分层规则对评价指标识别并分层;然后将整体增益速度的趋势和状态“积”性集结得到相应的激励量,并根据激励导向以组合赋权的方式确定指标权重。最后,通过中国31个省域的科技发展水平实证分析对方法的应用过程进行了说明。该赋权方法从激励的视角充分考虑了被评价对象在各指标上的发展趋势和发展潜力,据此,被评价对象可判断自身优势和不足,决策者也可统筹把握被评价对象整体发展情况,实现精准引导、统筹兼顾和公平激励。

河南省可持续发展实验区发展水平评价及推进策略

可持续发展实验区在区域协调发展中发挥着重要的示范引领作用,文章突破聚焦于东部省市可持续发展实验区研究成果,针对河南省可持续发展实验区现状分别从经济、社会、资源和环境四个方面,共分4组24个评价指标构建发展水平评价指标体系,并以2015—2019年河南省内13个国家级、20个省级可持续发展实验区为研究对象,结合河南省地域发展特征对其可持续发展水平进行综合分析与评价.结果表明:(1)整体来看,河南省可持续发展实验区可持续发展水平有所降低,科技创新能力有待提高;(2)从层级上来看,国家级可持续发展实验区发展较为平稳,省级可持续发展实验区在空间上呈现动态集聚;(3)从发展类型来看,城镇型实验区可持续发展水平随着城市化进程加快正逐渐降低;粮食主产区内实验区经济发展对于其可持续发展水平具有正向促进作用.因此,对河南省可持续发展实验区进行分级管控、分类施策,同时,强化技术创新提高整体河南省可持续发展水平,能够更充分发挥河南省可持续发展实验区引领带动区域可持续发展的作用.

地方政府生态保护力度如何影响经济高质量发展?

地方政府生态保护的策略性行为选择是影响其生态保护力度的关键因素。该研究在对各省份生态保护力度指数测度的基础上,将生态保护与有为政府相结合,从策略性行为选择的视角,考察地方政府生态保护力度对经济高质量发展影响的内在机理和市场化程度在两者关系中的调节机制,并以2008—2021年中国30个省份的面板数据为样本,构建静态面板模型和空间杜宾模型对上述机理机制进行实证检验。结果表明:①各省份的地方政府生态保护力度指数均显著提升;地理分区的地方政府生态保护力度指数,表现为东部、中部和西部地区之间依次递减,南方地区大于北方地区的格局;而增速则相反,东部、中部和西部地区之间依次递增,南方地区慢于北方地区;地理分区之间的地方政府生态保护力度梯度差表现为缩小的趋势;地方政府生态保护力度对经济高质量发展的影响表现为“U”型特征,当前的影响表现为正向促进作用。②本地政府生态保护力度对邻地经济高质量发展的影响具有空间溢出效应,具体溢出效果取决于地方政府间生态保护的策略性行为选择;地理邻近省份间的策略性行为选择为“逐底竞争”,其空间溢出效应表现为反向;经济邻近省份间的策略性行为选择为“竞相向上”,其空间溢出效应表现为同向。③市场化程度是地方政府生态保护力度影响经济高质量发展的调节机制;市场化程度对二者关系的影响表现为强化效应;且随着市场化程度提升,地方政府生态保护力度对经济高质量发展影响的“U”型曲线拐点值将向左移动。
