在供给侧结构性改革凸显动能转换的时代背景下,本文基于2006—2017年我国30个省份动态面板数据,实证检验了技术创新对我国居民消费升级的影响以及产业结构调整的中介作用。研究发现：(1)作为供给侧结构性改革的核心,技术创新对两类消费升级产生了显著的正向影响。创新效率越高,越有助于促进我国居民从温饱型消费向发展型和享乐型消费过渡;(2)消费升级存在时间黏性,当期消费会受到往期消费水平的正向影响,而技术升级有助于打破这种黏性,助推消费升级;(3)产业结构升级在技术创新和消费升级之间存在显著的中介效应,体现了技术进步、产业结构调整对拉动内需的“引擎”作用。 相似文献

基于比较视角,运用协方差分析模型及2011-2018年制造业数据进行实证研究,探讨供给侧改革以来制造业创新绩效的变化及其成因.研究发现,在技术研发阶段,供给侧改革显著促进研发绩效提升,原因是工艺创新强度、R&D投入强度得到加强并对研发成果形成正向作用;在成果转化阶段,供给侧改革促进市场绩效提升不够显著,研发成果对市场收益发挥积极作用不显著. 相似文献

与国外隐形冠军企业“专注、聚焦”的发展战略不同，近一半的中国隐形冠军企业选择“多元化”突破发展瓶颈。已有多元化战略影响因素研究大多考虑某单一或多个要素，尚未深入探讨各因素之间的内在逻辑关联。因此，基于21家中国制造业单项冠军示范企业数据，采用fsQCA方法，结合“隐形冠军”及多元化战略研究，探究“供给侧—需求侧—外部环境”前因条件对中国隐形冠军企业产业多元化发展的影响。研究结果表明，中国隐形冠军企业产业内多元化分为需求侧协同型、关系驱动型和技术驱动型3种模式；产业间多元化分为能力驱动型、混合驱动型和环境驱动型3种模式。其中，需求侧驱动为产业内多元化提供内生动力，外部环境是产业间多元化的重要推动力，企业核心能力以不同形式对两类产业多元化起到显著驱动效应。本文基于组态观的整体视角，检验和拓展了中国情境下隐形冠军企业多元化发展路径，对于克服隐形冠军企业“成长的天花板”，推动中国制造业企业转型升级和中小企业融通创新具有重要意义。 相似文献

制造业服务化是世界制造业发展趋势。以供给侧结构性改革为背景,针对制造业服务化探讨了企业人均能源消耗、产业链升级、创新能力对企业生产率的共同影响机制。研究发现：制造业服务化与企业生产率正相关,但受到企业人均能源消耗的负向调节作用。同时,产业结构调整与企业创新能力强化了制造业服务化与企业生产率之间的正向关系。结论对供给侧结构性改革下的中国企业转型升级具有理论价值与实践启示。 相似文献

一方面,大数据使整合更大范围内的互补资源成为可能,制造业服务供给能力日益集中;另一方面,大数据也提供了满足服务需要的更多实现形式与获取途径,制造业服务需求日益异质;如何响应数据赋能对制造业服务化的供给侧、需求侧以及两者匹配的三重冲击决定了制造企业服务化的成败。基于“供给-需求”匹配视角,本文利用美的单案例扎根探究,采用商业模式创新框架分析数据赋能驱动制造企业服务化的作用路径,研究表明：（1）数据赋能分别通过战略导向、数据特征利用与多主体实时交互,继之以资源利用为共通媒介,然后影响价值创造、价值传递、价值捕获三个维度来驱动制造企业服务化;（2）数据赋能驱动制造业服务化表现为“数据赋能-工业数字化能力、产品数据利用能力、客户价值互动能力的提升-工业服务化、客户服务化与价值服务化的组合影响”的动态过程。本研究引入了制造业服务化的需求侧,扩展了数据赋能驱动制造企业服务化的作用路径,为制造企业服务化提供了以“供给-需求”匹配为核心的理论指导。 相似文献

以供给侧改革为背景,基于技术进步、金融发展与产业升级间的逻辑关系,选取2000—2014年新疆相关数据,首先通过灰色关联分析证明技术进步与产业升级之间存在关联性,在供给侧改革下新疆需要通过技术创新推动产业升级;进而采用分位数回归方法研究金融业发展对产业升级的影响,结果发现随着产业结构升级对金融的要求不断提高,金融业并没有很好地发挥出对产业升级的支持作用,在供给侧改革下新疆金融业需要得到进一步改革和完善。 相似文献

经济理论服务于经济实践,目前需要理论上为中国的供给侧改革提供更多的经验借鉴。本文对三个知识溢出效应指标,结合制造业进行了新的概念界定。把一些经典的经济学理论应用到本文的研究主题上,构建了全新的适合“中国本土”的理论研究框架。实证分析采用三维动态模型,摒弃了传统的二维静态模型。通过定量分析,找出问题的症结所在,进而有针对性地提出解决之策,以指导实践。政策建议中提出了以下主要观点：制造业空间“热点”和“冷点”的集聚,在更大空间范围上,正是“热冷”的空间异质性表现;为区域经济增长的锁定效应解锁,需要依靠政府更有力的制度供给;时间性制度滞后变量影响不显著,需要更为关注人为因素的制度滞后所导致的制度供需结构性矛盾;制造业的专业化、市场化和区域之间的合作有利于知识溢出;发挥内在经济与外在经济效应,加快制造业向创新驱动型转变;制造业垂直纵深升级发展等。供给侧改革中产业结构调整出现的失业问题,政府不应缺位,提出“予千金”,不如“授一技”的观点,来避免失业率的大幅上升。 相似文献

根据2013—2017年制造业上市公司数据，本文在手工收集企业实施“互联网+”指标的基础上，实证检验了“互联网+”战略对企业研发投入的影响及其对不同企业的异质性作用。结果表明，“互联网+”战略对企业研发投入具有显著促进作用；这种促进作用只在东部地区显著，而在中、西部地区不显著；“互联网+”战略更能促进国有和民营企业进行研发投入，对外资企业研发投入存在抑制作用；生产率影响了“互联网+”战略与企业研发投入的关系，生产率较高的企业实施“互联网+”战略的创新效应更强。扩展检验发现，“互联网+”战略对企业研发投入的促进作用具有持续性，并且其影响程度逐年增强。研究结论为进一步实施“互联网+”战略以及制造业创新发展提供了微观层面的经验证据及决策支持。 相似文献

This study examined how students who had no prior experience with videoconferencing would react to the use of videoconferencing as an instructional medium. Students enrolled in seven different courses completed a questionnaire at the beginning of the semester and again at the end of the semester. Students at the origination and remote sites did not differ in their reactions toward videoconferencing but there was a significant difference for gender. Women reacted less favorably to videoconferencing. Compared to the beginning of the semester, students reported significantly less positive attitudes toward taking a course through videoconferencing at the end of the semester. There were no significant differences in students' attitudes toward videoconferencing across courses at the beginning of the semester but there were significant differences across the courses at the end of the semester. The results suggest the need for better preparation for both students and instructors. 相似文献

With great care, Dr. ZHOU Zhonghe takes out a package wrapped by cotton tissue from a drawer and says: "This is the gem of our collections: the fossil of a bird that lived 125 million years ago!" Then, pointing at a tiny mound, he explains: "Look, this is the claw and that is the head. It was in the egg shell and ready to hatch ... The species fell into a family of waterside inhabitants." 相似文献

A computer-mediated group is a complex entity whose members exchange many types of information via multiple means of communication in pursuit of goals specific to their environment. Over time, they coordinate technical features of media with locally enacted use to achieve a viable working arrangement. To explore this complex interaction, a case study is presented of the social networks of interactions and media use among members of a class of computer-supported distance learners. Results show how group structures associated with project teams dominated who communicated with whom, about what, and via which media over the term, and how media came to occupy their own communication niches: Webboard for diffuse class-wide communication; Internet Relay Chat more to named others but still for general communication across the class; and e-mail primarily for intrateam communication. Face-to-face interaction, occurring only during a short on-campus session, appears to have had a catalytic effect on social and emotional exchanges. Results suggest the need to structure exchanges to balance class-wide sharing of ideas with subgroup interactions that facilitate project completion, and to provide media that support these two modes of interaction. 相似文献

Electronic data interchange (EDI) provides means for interorganizational communication, creates network externalities, requires an advanced information technology (IT) infrastructure, and relies on standards. In the diffusion of such innovations, institutional involvement is imperative. Such institutions contain governmental agencies, national and global standardization organizations, local government, and nonprofit private organizations like industry associations. The last type of organizations we call intermediating institutions. They intermediate or coordinate ("inscribe") the activities of a group of would-be adopters. Unfortunately, little is known of how these organizations shape the EDI diffusion trajectory. In this article we examine one specific type of intermediating organizations?industry associations?and how they advanced the EDI diffusion process in the grocery sectors of Hong Kong, Denmark and Finland. We identify six institutional measures, placed into a matrix formed by the mode of involvement (influence vs. regulation) and the type of diffusion force (supply push vs. demand pull), that can be mobilized to further the EDI diffusion. Industry associations were found to be active users of all these measures to varying degrees. Their role was critical especially in knowledge building, knowledge deployment, and standard setting. Furthermore, institutional involvement varied due to policy and cultural contingencies and power dependencies. 相似文献

The increasing prospects of digital piracy has prompted the perceived need by electronic publishers to adopt technical systems of protection, and governments to reform their copyright laws. This article is a preliminary study of the management of intellectual property by electronic publishers, defined as those involved in the production of online databases, and CD-ROMs. It focuses on three main issues: (1) how electronic publishers view the increasing threat of piracy; (2) the methods of protection employed to protect intellectual property in digital format; and (3) the importance of technological protection of intellectual property in electronic publications. The analysis is based on a sample of 23 UK electronic publishers. The interviews revealed an interesting assortment of protection methods and did not show that technological protection was a preferred way. Instead, the means of protection, in addition to copyright law, comprised niche markets, pricing, trust, bad publicity, and nontechnical and technical means. 相似文献

Long-standing conflict between domain name registrants and trademark holders prompted the Internet Corporation for Assigned Names and Numbers (ICANN) to create a global, mandatory arbitration procedure known as the Uniform Dispute Resolution Policy (UDRP). The UDRP has been used in 2166 cases involving 3938 domain names as of 1 November 2000. The policy gives the initiator of a complaint, generally a trademark holder, the right to choose which ICANN-accredited dispute resolution service provider (RSP) will handle the case. During the preparation of the UDRP,some feared that complainant selection would lead to "forum shopping" that might bias the results. This article performs a statistical assessment of the forum-shopping thesis and finds support for it. There are statistically significant differences in the various RSPs' propensity to take away names from defendants; there are also major differences in the number of cases brought to each RSP. RSPs who take away names have the larger share of cases. The study examines other variables that might explain differences in market share, such as price, the plaintiff's nationality, or the time taken to decide a case. It finds that nationality and time also are correlated with market share. The study concludes that shopping for a favorable outcome is an important factor in the UDRP. 相似文献
