海峡两岸证券业经营效率比较研究:基于Metafrontier方法

本文将Metafrontier思想与BCC-DEA模型相结合,综合应用Metafrontier DEA方法、Malmquist全要素生产率指数和Tobit模型,客观地评价具有不同生产技术的两岸证券商的经营效率。结果表明:台湾证券商发展水平趋同,大陆证券商良莠不齐,但竞争力逐渐提升;台湾证券商技术水平落后于大陆;大陆全要素生产率逐渐改善,台湾逐渐衰退;资产总额、负债比、地区生产总值是影响技术效率的关键因素,负债比、经济自由度、地区生产总值是影响技术落差的关键因素;金融危机对两岸证券业冲击显著。     

Technology competencies in competitive environment

Although prior studies suggest that technology competencies play a significant role in firm innovation and competitiveness, what and how technology competencies interacted with competitive environment affect firm innovation has not been fully understood. This paper fills this research gap through a questionnaire survey of 165 firms together with a number of interviews drawn from the Taiwan's information and communication technology (ICT) industry. The results suggest that capabilities of exploring or exploiting technological opportunities, core technology capability, and autonomy of R&D decisions are particularly important to firm innovation in a highly competitive environment, whereas over commitments to existing technologies may constrain a firm's innovation especially in such environment. Moreover, different types of competitive environment require different types of technological competencies to enhance firm innovativeness. This paper contributes to the existing theory by examining the joint effect of technology competency and competitive environment on a firm's innovation.     

Beyond the technology adoption: Technology readiness effects on post-adoption behavior

Technology readiness (TR) refers to people's propensity to embrace and use new technologies. Nowadays, the proliferation of technology-based products and services brings consumers not only benefits but also frustration over ineffective use of products and services. A key factor, therefore, in the diffusion and success of these products and services is how well-prepared consumers are for new technologies. Although some studies examine the relationships between TR and technology adoption, the long-term survival and substantial success of firms rely on the continued use of such technology rather than first use. This study focuses on post-adoption behavior and investigates how TR affects the continued use intention of new technology. Specifically, the study classifies usage behavior into the usage rate of basic functions, the usage rate of innovative functions, and the variety of use of innovative functions. The article then, examines how each dimension (optimism, innovativeness, discomfort and insecurity) of TR influences consumer usage patterns, and how usage patterns affect repurchase intention through consumer satisfaction. The empirical results from IPTV users in Korea show that each dimension of TR has a significantly different influence on usage patterns. The findings show that usage patterns, particularly the use of innovative functions, have a significantly positive impact on consumer satisfaction and repurchase intention. Finally, the article suggests several managerial implications and directions for further studies.

关于国际技术扩散对我国贸易竞争优势影响的思考

在经济全球化的进程中,一国的技术进步不仅依赖于本国的创新,而且还需要充分利用他国的先进技术资源,并通过各种渠道的技术扩散和技术外溢来促进本国的技术进步与经济增长,从而在国际市场上提升本国的贸易竞争优势。结合我国现状从宏观和微观两个角度分析了国际技术扩散对我国贸易竞争优势的影响。     

中国汽车出口分析

汽车工业,又被称为“工业中的工业”,它是一国工业化的中期进程一个最为重要的产业。近年来中国的汽车企业逐渐开始走出口的道路,与中国的汽车产业发展程度相比,这种出口并不能说明中国已经是一个汽车生产的强国,反而是中国汽车产业真正开始起步的征兆,因为这种出口带动了汽车工业的自主研发的开始。本文通过对中国汽车出口现状和原因的一些分析,指出汽车工业发展中还需要注意的一些关键性问题。

城市科技创新人才政策扩散动力因素时空差异研究

科技创新人才是城市提升创新能力的核心资源,是科技进步的关键要素。科技创新人才政策作为城市争夺人才的工具,被各个城市广泛采纳和使用。以161个城市为研究对象,运用事件史分析方法,探寻城市科技创新人才政策扩散的动力因素并进行时空差异分析。研究发现,城市科技创新人才政策扩散具有双重动力因素：在需求拉动因素中,经济发展水平和财政收入是影响城市科技创新人才政策扩散的主要因素;在压力推动因素中,行政指令、府际竞争和社会舆论显著影响城市科技创新人才政策扩散;在政策扩散平稳增长期,双重动力因素共同作用于政策扩散过程,而在政策扩散加速和减速增长期,城市科技创新人才政策扩散动力因素存在差异;在东、中部地区,压力推动因素占据主导,而在西部地区,双重动力因素都发挥重要作用。     

数字化能否调节产品创新与服务转型的交互效应——基于A股制造业上市公司的实证研究

基于2012—2019年沪深两市668家A股制造业上市企业面板数据,实证检验产品创新与服务转型对企业绩效的交互效应,利用Python文本挖掘技术构建数字化指标,研究数字化对两者交互效应的调节作用。结果表明：产品创新和服务转型两者间的交互效应与制造业服务化水平有关,随着服务化水平提高,交互效应表现为U型关系;数字技术能够显著促进产品创新与服务转型协同发展,使两者交互的U型曲线拐点向左移动。进一步分析表明,大型民营企业引进数字技术对两者交互效应的调节作用更为显著。结论有利于促进制造企业产品创新与服务转型协同,对于实现高质量发展具有重要现实意义。
