农民专业合作社主导因素与规范找寻

农民是农民专业合作社的产品供应者和理论受益者,对专业合作社的发展起决定作用。我国农民专业合作社的变迁路径是按照市场化取向由农民主导和选择的。我国农民专业合作社的发展正处于规范与发展并重的时期,是制度变迁的深化阶段。发展农民专业合作社符合农民的利益,应尊重农民的主体地位,正确处理政府推动与尊重农民意愿的关系,从而为进一步推动农民专业合作社健康、持续发展提供理论依据。     

我国台湾地区太阳能光伏产业演进的案例分析

太阳能光伏产业正在成为许多国家和地区重点发展的产业。台湾地区利用以往半导体产业与太阳能产业的关联优势,从太阳能电池环节开始向上下游整合。一方面,通过建设新厂、企业相互参股、异地合资建厂等方式,消除硅材料缺乏的瓶颈,提高生产设备自给率。另一方面,通过外销、在大陆合资设立厂等方式,突破台湾本地市场规模限制,获取规模经济。同时,对薄膜太阳能产业进行战略布局,逐步建立健全太阳能产业链,使台湾成为世界第二大太阳能产业产地。台湾太阳能光伏产业发展为产业演进研究提供了典型案例。     

甘肃省产业空间格局演变及特点

以甘肃1995年以来的数据,借助Arcview软件制图,分析了甘肃省经济空间结构、三产业空间格局演变过程及特点。结果表明:1995年以来,甘肃省经济空间结构没有显著变化,呈现以兰州市为极点的单极核经济结构;产业结构逐步优化,工业发展是甘肃省经济增长的主要动力,矿产资源分布状况与工业化存在内在的联系和耦合关系,也是经济空间结构形成和演化的重要原因。     

中国经济区划与区域经济关系演化

一个国家的国民经济是作为一个整体系统而存在的,其根本的目标在于实现整体的经济发展。然而,在历史上．我国东部地区与中西部地区一直存在着明显的经济发展差距。如何缩小这一差距,实现各地区经济的共同发展,是我国经济发展中不容回避的一个重大问题。文章描述了建国后各阶段区域经济发展的背景、实践措施及其影响,对如何缩小各地区经济差异,构建和谐社会提出了建议,得到了启示。     

两权分离与公司治理的演进——英美经验与我国实践

公司治理的演进过程也是所有权和控制权以及经营权分离的过程。通过对英美国家公司发展不同时期两权分离的历史考察,发现两权分离与公司治理演进之间存在依存关系：两权分离依次经历了所有权和经营权分离、所有权和控制权分离、控制权和经营权分离和同股不同权等阶段,不同形式的两权分离带来不同的公司治理问题,从而产生相应的治理手段,推动着公司治理的演进。通过对中国企业改革和发展过程的历史回顾也证明了两权分离与公司治理之间存在共同演进关系。针对研究发现,最后提出了我国公司治理改革的方向性建议。     

Exploring the core factors of online purchase decisions by building an E-Commerce network evolution model

With the continuous development of the Internet and information technology, online shopping has become a popular purchase mode. The in-depth analysis of consumer decision-making in online shopping is an important issue. Our purpose is to study how the factors of the shopping web pages corporately affect online purchase decisions and determine which are the core factors that affect consumer purchase decisions. We screen the influencing factors on the shopping webpage and deploy e-commerce network evolution based on various weight combinations of these factors to generate sales distributions of online products. By comparing these simulated sales distributions to the real data, the optimal weight of each factor is obtained. The results show that sales volume and the number of high-quality negative comments are the most important factors influencing consumers' decision-making, the number of comments and the number of comments with pictures are relatively minor factors, store type and video presentation of the products have the least impact. The optimal simulated sales distribution is very close to the real case and verifies that the introduced network evolution technology is applicable. The proposed model can be used as a uniform evaluation platform for correlational study, which is an important link in the purchase research chain.     

Spatial Pattern and Spatiotemporal Evolution of China＇s National Historic Cities

基于地理信息系统空间分析技术,从微观、中观、宏观三个尺度对我国国家历史文化名城的地域分布差异和发展演变特征进行分析探讨,结果表明：在微观的市县级范围内,县级及以下名城的分布相对分散,地级及以上名城在我国东部和中部县市相对集中;在中观的省域范围内,1982年以来的一、二、三批名城在省域覆盖范围内具有较为明显的东南部、北部、中西部重心格局演变的特征;从全国范围来看,国家历史文化名城空间上总体表现为由东到西数量递减的非均衡分布特征,时空演变总体表现为由大中城市向中小城市,由中心城市、中部城市向边缘城市、地域特色城市,由直辖城市、省会城市向地级城市、县级城市、甚至城市的一个行政区扩展的特征。国家历史文化名城的批复发展在考虑各尺度区域范围内的等级差异和不均衡分布的基础上走向了科学化、细致化。     

Analyzing Daqing＇s Urban Spatial Form Evolution： Basing on the Technology of RS and GIS

以我国目前最大石油城市——大庆市为研究对象,选取1984、1995、2007年3个城市建设关键时间节点,以Landsat MSS、TM卫星影像为主要数据源,利用GIS技术提取城市建设用地规模、形态、增长幅度、区位坐标等信息,计算城市空间扩张速度、强度、城市空间形态紧凑度、分维指数、城市增长理性程度等空间特征量,分析大庆市1984年以来城市空间扩张现象和特征,并结合经济社会统计相关数据及区域分析方法,探究其因果关系。研究认为,大庆市城市空间扩张与形态演化具有石油城市发展的典型性和一般规律,表现出建设用地总量大、扩张速度快、强度高、增量分布不均衡、空间形态不规则、紧凑度低、城市中心地迁移方向与用地扩张基本一致等特征。这些现象和特征的主要形成原因包括石油开发战略指向、自然环境约束、交通设施引导、城市规划调控、中心地功能变迁等五个方面。     

China’s telecommunications evolution,institutions, and policy issues on the eve of 5G: A two-decade retrospect and prospect

Over the past two decades, China’s telecommunications industry has witnessed drastic market reform, steadfast institutionalization, and volatile technological changes, which have driven exponential industry expansion. This paper offers an updated longitudinal and comprehensive review on this reform process on the eve of 5G (the fifth generation mobile communications networks). First, the paper segments the two-decade reform crusade into discernible phases, each of which is embedded with different policy drives. These reform phases are then pattern-matched against the subtleties of the overall institutional, technological, and market backdrop. A series of policy issues are identified through a systematic examination of industry phenomena over the reform course. Finally, the status of research is assessed regarding China’s telecom industry and reform, based on which, knowledge gaps are identified and future research agenda suggested. Conclusions are made regarding future reform and research imperatives. The paper advances the understanding of China’s telecom reform, development, and the underlying policy issues. It updates and expands previous works on similar topics. Overall, this study provides important theoretical, managerial, and policy implications.     

The Narrow and Broad Approaches to Evolutionary Modeling in Economics

Some models in evolutionary economics rely on direct analogies to genetic evolution, assuming a population of firms with routines, technologies, and strategies on which forces of diversity generation and selection act. This narrow conception can build upon previous findings from evolutionary biology. Broader concepts of evolution allow many or just one adaptive entity, instead of necessarily requiring a population. Thus, an institution or a society can also be understood as an evolutionary entity. Both the narrow and broad approaches have been extensively used in the literature, albeit in different literature traditions. I provide an overview of the conception and development of both approaches to evolutionary modeling, and argue that a generalization is needed to realize the full potential of evolutionary modeling.
