科技期刊更名的负面影响及其应对措施

从20世纪80年代开始,我国期刊刊名变更现象日趋严重,而科技期刊更名对期刊的知名度、稿源、发行量、社会影响,以及期刊的查阅和管理均会带来负面影响.在分析这些负面影响的基础上,提出了应对措施.     

Lean information for lean communication: Analysis of concepts,tools, references,and terms

Communication and information processes are vital in any company. The use of lean manufacturing concepts applied to the communication and information process aims to reduce waste and make the flows leaner and simpler. Lean information is a new strand of lean concepts and applications. The purpose of this study was to analyze quantitatively the publications concerning the subject, outlining an overview for the new research field of lean communication. Aiming for a deeper understanding, the concepts of lean information were applied in a real process. The quantitative analysis was carried out to find the main authors and works, as well as the main terms used in related works. We used the methods of citations works, co-citation references, and co-occurrence of words using the VOSviewer software. This software was primarily designed to analyze bibliometric networks in order to create, visualize, and assess maps based on network data generated from queries in journals. We found a lack of a methodology for the development and implementation of lean information concepts. We observed a gap which had not been addressed yet, that is, mapping communication flows and developing and implementing lean information. Moreover, there was no method for improvement, implementation, and control.     

How to facilitate knowledge diffusion in complex networks: The roles of network structure,knowledge role distribution and selection rule

The diffusion of knowledge within organizations provides opportunities for interpersonal co-operation, improves creative ability and therefore leads to competitive advantage. Focus of prior literature on knowledge diffusion has been on identifying factors that influence individuals' behavioral intentions to seek and share knowledge. However, knowledge diffusion as an enigmatic, emergent and organizational-level process is more than the simple aggregation of individual attributes and needs to be further investigated. Accordingly, this study focuses on three distinct system-level factors, i.e., architectures of connections among individuals, distributions of knowledge roles and designs of selection mechanisms and analyses their effects on knowledge diffusion. To be more specific, we examine three distinct knowledge roles: seekers, contributors and brokers. We also distinguish between three types of selection mechanisms: objective selection mechanisms, feedback-based selection mechanisms and random selection mechanisms. By conducting agent-based simulations on four representative networks, i.e., regular networks, random networks, small-world networks and scale-free networks, our results show that the optimal knowledge diffusion performance can be achieved on scale-free networks where all agents implement objective mechanisms and show characteristics of brokers. Moreover, our results (a) highlight the significance of brokers, (b) illustrate the superiority of objective selection rules and (c) demonstrate that scale-free networks provide an optimal framework for knowledge diffusion. Furthermore, we also find the interdependent relevance of these three factors to knowledge diffusion and propose a qualitative explanation of these findings.     

风险投资声誉、智力资本与企业价值

风险资本与智力资本的有效协同能够实现创业企业知识、资本、管理与创新的完美结合,而拥有高声誉背景的风投在利用其经验和广泛的社会关系帮助企业快速成长方面作用更加突出。本文将创业企业的智力资本划分为人力资本、结构资本、创新资本与社会资本四个组成部分,基于风险投资声誉的视角,探讨风险资本与智力资本的协同关系。结果显示：高声誉风险投资在创业企业人力资本和结构资本两方面的协同效应并不显著,而与创新资本和社会资本两方面的协同效应突出,尤其与社会资本的协同效应能够显著提升创业企业的内在价值。该结论表明高声誉的风险投资机构亟需对目标企业的人力资源、战略规划等方面积极关注,并提供更多的增值服务。     

众创空间的创业孵化模式研究——来自广州的调查与分析

众创空间在高速发展的同时建设水平参差不齐,孵化效果相去甚远。本文选取了广州市的众创空间作为调研对象,调研众创空间的创业孵化模式及其效果,比较不同孵化模式的优劣。研究发现,孵化模式优劣的影响因素主要有三个方面：一是投入孵化要素的侧重点;二是众创空间对孵化模式的执行力度;三是孵化模式与孵化企业相互适应程度。从优化孵化模式出发,给众创空间的发展提出三点建议：一是众创空间应结合自身、行业、地区情况设计孵化模式;二是围绕孵化模式建立灵活的孵化机制;三是积极拓展投融资渠道。     

版权强国背景下版权保护对我国版权产业发展的影响研究

版权保护对我国版权产业发展具有重要的意义。基于我国2016年的相关数据,构建指标体系,测算出版权保护强度这一版权保护的关键因素,并结合外商投资、城镇单位文化、体育和娱乐业就业人数、文化、体育和娱乐业固定资产投资、每十万人口各级学校平均在校学生数共五个因素来分析版权保护对版权产业发展的作用机制。研究发现,版权保护强度、外商投资以及城镇单位文化、体育和娱乐业就业人数对版权产业发展具有不同程度的正向影响,其他两个因素则不显著,并据此相应地提出促进我国版权产业发展的对策建议。     

网络视角下智慧城市外部智慧性作用机制探究

经济全球化快速发展使得城市之间的各类联系日益增多,要实现城市的智慧发展,不能仅关注城市内部的创新,也要重视其在整体网络中的表现。在城市网络理论视域下,采用社会网络分析法,将智慧城市在城市网络中的位置与作用定义为其外部智慧性,并以2016年中国193个试点智能城市为样本,利用主要企业总部-分公司布址数据构建智慧城市网络,探究智慧城市的外部智慧性对其内部智慧性绩效评估的影响与作用机理。研究发现,智慧城市在网络中的点入度、点出度、结构洞与互惠性等属性均对其内部智慧性的评估结果有显著的影响作用。新兴智慧城市要提升综合竞争力,应该识别自身的网络定位,增强与其他城市的联系与合作,形成内外联动,实现智慧城市发展的各项目标。     

跨区域财政转移制度的耕地保护效应——以新增建设用地使用费为例

跨区域财政转移制度是解决耕地保护区域非均衡的重要工具,其通过管制弱化区域和管制强化区域之间的横向财政转移,使得不同区域均能享受到国土空间优化带来的福利提升,有助于耕地保护的实施。本文初步尝试将新增费缴纳、新增费分配过程有机结合,视为横向跨区域财政转移支付,即新增费由建设用地指标多的非农发展区流向耕地保护任务重的农地保护区,并考察这种以新增费为载体的跨区域财政转移制度的耕地保护作用机理。在此基础上,本文采用中国2005—2015年间省级面板数据,通过建立动态面板计量模型和引入系统GMM估计方法进行实证检验。研究结果表明：以新增费为载体的省际横向跨区域财政转移制度有助于调动地方政府保护耕地的积极性,达到耕地保护的目的,但是其发挥的作用非常有限。进一步探讨新增费的两个主要组成部分——新增费缴纳和新增费分配的耕地保护效应大小可知,相比于新增费分配,新增费缴纳的耕地保护效果更好。本文研究结果有助于完善以新增费为载体的省际横向跨区域财政转移支付制度,促进耕地资源保护。
