任波  黄海燕 《南京体育学院学报(社会科学版)》2020,34(1):49-58

在新时代体育产业发展进程中，我国体育产业结构性失衡问题显得尤为突出，而推进体育产业供给侧结构性改革对破解体育产业结构性失衡具有现实意义。采用供给经济学、产业经济学等相关理论，剖析我国体育产业结构性失衡的表现形式，解构我国体育产业结构性失衡的形成原因，探寻我国体育产业结构性失衡的供给侧破解路径。研究表明：1）我国体育产业结构性失衡表现在：体育产业的产值结构、就业结构、供给结构等方面。2）体育产业结构性失衡的形成原因有：经济体制决定体育产业结构、体育发展战略固化体育产业结构、大众需求结构钢化体育产业结构。3）体育产业结构性失衡的供给侧破解路径为：明晰政府与市场边界，发挥市场在体育资源配置中的决定性作用；完善体育产业结构政策，发挥体育产业在体育发展战略中的作用；推进体育供需平衡，发挥体育产业在促进体育消费中的作用。  相似文献   

保定农村电子商务发展策略研究     

张楠楠  柴若冰 《保定学院学报》2020,(1):130-136

“互联网+”背景下,电子商务与农村经济的结合为农业发展带来了新的思路,但同时农村电子商务在发展中也面临诸多问题。引入比较优势指数法对保定各地优势农产品进行测算,并就保定农村电商发展现状进行实地调研,结果表明:保定农产品网店已初具规模,店铺分布呈现非均衡性,经营主体以青年人为主,原材料供应型店铺占主导地位,电商发展的配套系统如人才、科技信息服务平台、物流配送系统等仍不完善,成为制约电商发展的主要因素,亟须各部门配合综合加以解决,形成农村电商的整体合力,为推动农村产业结构的转型升级提供助力。  相似文献   

粤港澳大湾区经济中心对粤北地区的经济辐射作用分析——以清远市为例     

周婷 《清远职业技术学院学报》2020,(2):12-16

发挥经济中心对周边地区的经济辐射作用对一个区域的经济协同发展具有重要意义。粤北地区特别是清远市可以说是藏在粤港澳大湾区经济焦点下的盲点。借助地理距离优势,跨越发展鸿沟,使周边地区与粤港澳大湾区实现融合式互动和一体化发展,是一个具有重要研究价值的问题。可以将粤港澳大湾区及其周边地区作为一个城市群,描述和测算其基本发展现状及经济分布格局,探索经济辐射的必要性与可能的辐射路径。  相似文献   

北京冬奥会筹备对运动休闲基地建设的示范作用研究     

李杰桃 《广州体育学院学报》2020,(3):43-45

北京冬奥会雪上项目将在张家口市崇礼区进行，冬奥会筹备工作的重点也就集中在了这个过去名不见经传的小镇上了。虽然距冬奥会开幕还有近2年的时间，但崇礼区作为滑雪运动圣地已蜚声海内外，国外专业滑雪运动队将它作为训练基地外，国内业余滑雪运动者也从全国各地涌向这里。如今，张家口市整个经济被冬奥会激活了，其产业结构也已因崇礼区滑雪运动休闲基地实现了从农业经济向资源旅游经济的转型。虽然冬奥会筹备是国家级的大事，但张家口崇礼区的建设筹备仍然对全国休闲运动基地建设具有示范指导意义。  相似文献   

我国体育产业发展与国民经济增长关系的实证研究     

李国  孙庆祝 《武汉体育学院学报》2019,53(1):43

运用文献资料、数理统计、VAR模型等方法，基于2005-2015年国民经济与体育产业发展统计指标数据，通过协整检验、向量误差模型、格兰杰因果检验、脉冲响应函数与方差分解等，对我国体育产业发展与国民经济增长之间的关系进行实证分析。研究结果为：（1）协整检验与向量误差模型分析显示，体育产业增加值与国民经济发展之间存在正相关长期协整关系，这种均衡关系具有反向修正机制，当均衡关系发生波动时，当期以-1.744 073倍的力度对前一期偏离状态进行调整，将其拉回到长期均衡状态；（2）格兰杰因果检验显示，体育产业发展是国民经济增长的Granger原因，但国民经济增长不是体育产业发展的Granger原因；（3）脉冲响应函数显示，国民经济波动对其自身发展与体育产业发展均产生负效应，体育产业对于自身冲击的脉冲响应呈正相关趋势，并且能够迅速促进国民经济发展。（4）方差分解显示，国民经济在其自身发展与体育产业发展中的作用呈逐渐增大之势，体育产业的影响则呈逐渐减小之势。最后，提出了"识别均衡关系：促进国民经济与体育产业互惠共生发展"、"衡量脉冲响应：降低国民经济与体育产业均衡发展负效应"、"重视方差分解：权衡国民经济与体育产业影响因素相对性"、"完善政策法规：优化国民经济与体育产业均衡发展制度环境"等促进国民经济与体育产业均衡发展的现实路径。  相似文献   

Business continuity of business models: Evaluating the resilience of business models for contingencies     

《International Journal of Information Management》2019

Company business models are vulnerable to various contingencies in the business environment that may unexpectedly render their business logic ineffective. In particular, technological advancements, such as the Internet of things, big data, sharing economy and crowdsourcing, have enabled new forms of business models that can effectively and abruptly make traditional business models obsolete. By disrupting or even diminishing companies’ revenue streams, environmental contingencies may present a significant threat to business continuity (BC). Evaluating the resilience of business models against these contingencies should therefore be a core area of BC. However, existing BC approaches tend to focus on the continuity of the resources and processes through which a particular business model is accomplished in practice but omit the business model itself. We argue that in order for BC approaches to become holistic and strategic, business models need to become a part of the BC considerations, entailing an expansion of the scope of BC from value preservation to value creation. We propose an approach of Strategic Business Continuity Management, which consists of two parts: (1) sustaining the continuity of the company business model (value preservation) and (2) evaluating and modifying the business model (value creation). We illustrate conceptually the value creation part with an example drawn from the sharing economy.  相似文献   

我国体育用品制造业转型升级与服务业发展的关系研究     

高贺  付志华  陈颇  赵恒  张铖  周良云 《南京体育学院学报(社会科学版)》2019,2(6):64-70

采用中国大陆东部、中西和西部三大经济区2008—2015年的面板数据，运用Johanson面板协整关系检验、Granger因果关系检验与面板数据误差修正模型，实证检验了我国体育用品制造业升级与服务业发展之间的因果关系。研究结果表明：不管是东部经济发达地区，还是中西部经济落后地区，体育用品制造业升级和服务业发展之间的协同互动关系均未建立起来，三大经济区体育用品制造业升级与服务业发展之间仅存在单向的因果关系。在东西部经济区，体育用品制造业升级是服务业发展的长期原因，但在中部经济区，服务业发展则是体育用品制造业升级的长期原因。从整体来看，虽然中国是一个体育用品制造和出口大国，但由于缺乏核心技术，产品全球竞争力较弱，国际话语权仍非常有限，与国内服务业发展相比，三大经济区体育用品制造业发展还处于相对较低的水平。最后，从互补性视角提出我国体育用品制造业与服务业发展的战略举措。  相似文献   

Culturalisation and devices: what is culture in cultural economy?     

Lizzie Richardson 《Journal of Cultural Economy》2019,12(3):228-241

Theorisation of culture is often absent from research on production in the creative and cultural sector. Further, cultural production has been largely untouched by the insights of the cultural economy approach. Culturalisation is a means of addressing the question of what constitutes culture and thus a cultural (economy) approach. It is the process by which culture and cultural production combine in the ‘operationalisation of the real.’ Culturalisation underpins much scholarship in this journal by posing the (economic) real as a problem of definition in order to illustrate the operations involved in its temporary resolution. The implications of this position need further addressing. There is a feedback between culture as a problem of definition and a cultural approach. Devices can interrogate the relationship between processes of cultural definition and the conceptual parameters of a cultural economy approach. Workshopping, projects and events are put forward as cultural devices emerging from a 10-month ethnography of literary performance in Bristol, England. This illustration shows firstly, how culturalisation occurs in a designated cultural sector to contingently realise culture; and secondly, the implicit logic of cultural economy as culturalisation, typified by the device as method, so as to open a debate concerning its implications.  相似文献   

Applying artificial intelligence technique to predict knowledge hiding behavior     

《International Journal of Information Management》2019

Drawing on psychological ownership and social exchange theories, this study suggests theoretical arguments and empirical evidence for understanding employee reactions to distributive, procedural, and interactional (in)justice — three crucial bases of employees’ feelings of social self-worth. Utilizing field data and artificial intelligence technique, this paper reveals that distributive, procedural, and interactional (in)justice contribute to higher levels of knowledge hiding behavior among employees and that this impact is non-linear (asymmetric). By reuniting the discourses of organizational justice and knowledge management, this study indicates that feelings of psychological ownership of knowledge and the degree of social interaction are mechanisms that work with organizational (in)justice to influence knowledge hiding behavior. The current research may inform contemporary theories of business research and provide normative guidance for managers.  相似文献   

Cognitive-inspired domain adaptation of sentiment lexicons     

Frank Z. Xing  Filippo Pallucchini  Erik Cambria 《Information processing & management》2019,56(3):554-564

Sentiment lexicons are essential tools for polarity classification and opinion mining. In contrast to machine learning methods that only leverage text features or raw text for sentiment analysis, methods that use sentiment lexicons embrace higher interpretability. Although a number of domain-specific sentiment lexicons are made available, it is impractical to build an ex ante lexicon that fully reflects the characteristics of the language usage in endless domains. In this article, we propose a novel approach to simultaneously train a vanilla sentiment classifier and adapt word polarities to the target domain. Specifically, we sequentially track the wrongly predicted sentences and use them as the supervision instead of addressing the gold standard as a whole to emulate the life-long cognitive process of lexicon learning. An exploration-exploitation mechanism is designed to trade off between searching for new sentiment words and updating the polarity score of one word. Experimental results on several popular datasets show that our approach significantly improves the sentiment classification performance for a variety of domains by means of improving the quality of sentiment lexicons. Case-studies also illustrate how polarity scores of the same words are discovered for different domains.  相似文献
