数字化转型是促进企业韧性形成并塑造竞争优势的重要手段。通过以广东省、江苏省等地区的339家企业为研究样本,实证研究发现:数字化转型对企业韧性具有显著正向影响;其中,数字化转型分别对探索式创新和利用式创新具有积极促进作用;同时,双元创新对企业韧性具有显著正向影响。进一步地,企业通过探索式创新和利用式创新分别在数字化转型对企业韧性的影响中起部分中介作用。研究从双元创新视角揭示了数字化转型对企业韧性的作用机制,验证了数字化转型与企业韧性的关系,也为实施数字化转型的企业通过双元创新来提升企业韧性应对不确定性风险提供了理论指导。 相似文献

什么样的数字创新生态系统有助于提高区域创新绩效是亟待解决的热点问题。采用必要条件分析(NCA)和模糊集定性比较分析(fsQCA)两种方法,对我国内地31个省(区、市)进行实证分析。研究发现:①数字企业、政府、高校及科研机构、数字创新基础设施、数字人才和金融服务是数字创新生态系统的关键构成,但单个要素并不是提高区域创新绩效的必要条件;②4种数字创新生态系统要素组态有助于提高区域创新绩效,构成的数字创新生态系统分别是政府引导的智力聚集型、企业开拓的环境支撑型、主体多元的综合发展型和企业主导的资本驱动型;③各地应因地制宜,选择合适的数字创新生态系统,培育区域创新新动能,助推“数字中国”新发展。 相似文献

Online labor markets have great potential as platforms for conducting experiments. They provide immediate access to a large
and diverse subject pool, and allow researchers to control the experimental context. Online experiments, we show, can be just
as valid—both internally and externally—as laboratory and field experiments, while often requiring far less money and time
to design and conduct. To demonstrate their value, we use an online labor market to replicate three classic experiments. The
first finds quantitative agreement between levels of cooperation in a prisoner’s dilemma played online and in the physical
laboratory. The second shows—consistent with behavior in the traditional laboratory—that online subjects respond to priming
by altering their choices. The third demonstrates that when an identical decision is framed differently, individuals reverse
their choice, thus replicating a famed Tversky-Kahneman result. Then we conduct a field experiment showing that workers have
upward-sloping labor supply curves. Finally, we analyze the challenges to online experiments, proposing methods to cope with
the unique threats to validity in an online setting, and examining the conceptual issues surrounding the external validity
of online results. We conclude by presenting our views on the potential role that online experiments can play within the social
sciences, and then recommend software development priorities and best practices. 相似文献

Flows of people,flows of ideas,and the inequality of nations 总被引:2,自引:0,他引:2
The present paper examines a neglected determinant of aggregate productivity: temporary cross-border flows of people. We hypothesize
that interaction between people from different nations facilitates the international diffusion of ideas, thus stimulating
aggregate productivity. In order to assess the causal impact of people flows on productivity, we construct an instrument for
people flows. By analogy to the trade/growth literature, this instrument is derived from a fitted gravity equation involving
geographic determinants of bilateral travel flows. Our cross-section analysis reveal that greater international interaction
leads to higher productivity; a very similar result, qualitatively as well as quantitatively, is obtained when we employ dynamic
panel data methods for the purpose of identification. 相似文献

We compare behavior in modified dictator games with and without role uncertainty. Subjects choose between a selfish action,
a costly surplus creating action (altruistic behavior) and a costly surplus destroying action (spiteful behavior). While costly
surplus creating actions are the most frequent under role uncertainty (64%), selfish actions become the most frequent without
role uncertainty (69%). Also, the frequency of surplus destroying choices is negligible with role uncertainty (1%) but not
so without it (11%). A classification of subjects into four different types of interdependent preferences (Selfish, Social
Welfare maximizing, Inequity Averse and Competitive) shows that the use of role uncertainty overestimates the prevalence of
Social Welfare maximizing preferences in the subject population (from 74% with role uncertainty to 21% without it) and underestimates
Selfish and Inequity Averse preferences. An additional treatment, in which subjects undertake an understanding test before
participating in the experiment with role uncertainty, shows that the vast majority of subjects (93%) correctly understand
the payoff mechanism with role uncertainty, but yet surplus creating actions were most frequent. Our results warn against
the use of role uncertainty in experiments that aim to measure the prevalence of interdependent preferences. 相似文献

Joseph Zeira 《Journal of Economic Growth》2011,16(2):135-156
This paper presents a model of innovations and endogenous economic growth with two main assumptions: first, the cost of searching
for innovations differs across innovations, and second, innovations take time to find. The paper shows that given these two
assumptions together, competition leads to patent races and to duplication of innovative activity. The paper then shows that
duplication significantly reduces the effect of scale on growth. It also shows that competitive R&D creates too much research
on easy innovations, and too little research on the difficult ones. Finally, the paper shows that risk sharing might increase
duplication and reduce growth. 相似文献

Sustaining cooperation in laboratory public goods experiments: a selective survey of the literature 总被引:5,自引:0,他引:5
Ananish Chaudhuri 《Experimental Economics》2011,14(1):47-83
I survey the literature post Ledyard (Handbook of Experimental Economics, ed. by J. Kagel, A. Roth, Chap. 2, Princeton, Princeton
University Press, 1995) on three related issues in linear public goods experiments: (1) conditional cooperation; (2) the role of costly monetary
punishments in sustaining cooperation and (3) the sustenance of cooperation via means other than such punishments. Many participants
in laboratory public goods experiments are “conditional cooperators” whose contributions to the public good are positively
correlated with their beliefs about the average group contribution. Conditional cooperators are often able to sustain high
contributions to the public good through costly monetary punishment of free-riders but also by other mechanisms such as expressions
of disapproval, advice giving and assortative matching. 相似文献
