数字创业高度依赖外部融资来源来促进增长。本研究旨在调查天使团体和风险投资（VC）基金如何影响数字新企业在启动和扩大阶段的增长。为了实现这一目标，我们分析了256家意大利新企业的372轮投资。主要结论有四个方面。首先，风险投资基金对数字新企业的增长有积极影响。其次，与数字新企业的整体样本一致，数字规模扩大显示出与风险投资正相关的线性增长路径。第三，数字创业公司获得的资金与增长之间的关系呈倒U形-我们样本集内的最佳水平为30万美元。最后，没有证据表明天使团体对数字新企业在启动和扩大阶段的增长做出了贡献。因此，这些研究结果进行了讨论，在现有的文献中的风险融资以及创业偏见的文献，为研究人员和从业人员在digital entrepreneurship.Background和aims：知觉压力已被视为一个危险因素的问题社交网站（SNS）的使用，但鲜为人知的是，混淆变量可能会调解或缓和这种关系的基本过程。为了回答这个问题，本研究探讨是否抑郁和焦虑介导的感知压力和有问题的SNS使用之间的关系，以及这些中介过程是否由心理弹性和社会支持调节。研究方法：研究对象为641名中国大学生，他们完成了匿名问卷，测量了感知压力、抑郁/焦虑、心理弹性、社会支持和有问题的SNS使用。结果如下：结果表明：（a）抑郁/焦虑在感知压力与问题SNS使用之间起中介作用;（B）心理弹性对抑郁/焦虑在感知压力与问题SNS使用之间的中介作用具有调节作用。具体而言，抑郁/焦虑的中介作用较强的个人与较低水平的心理弹性，与那些具有较高水平的心理弹性;（c）抑郁/焦虑的中介作用不受社会支持，虽然社会支持是负相关的抑郁/焦虑。讨论与结论：这项研究可以有助于更好地了解如何以及何时感知的压力增加了问题SNS使用的风险，并意味着提高心理弹性，防止问题SNS使用的重要性。
Digital entrepreneurship highly relies on external sources of financing to foster growth. This study aims at investigating how angel groups and venture capital (VC) funds affect growth of digital new ventures in their startup and scaleup phase. To address this aim, we analyzed 372 investment rounds regarding 256 Italian-based new ventures. The key findings are fourfold. First, VC funds positively affect the growth of digital new ventures. Second, digital scaleups, in line with the overall sample of digital new ventures, show a linear path of growth positively correlated with VC funding. Third, the relationship between funding received and growth in digital startups follows an inverted U-shape - with the optimal level within our sample set at 300,000$. Finally, no evidence emerges on the angel groups contribution to the growth of digital new ventures in both startup and scaleup phase. These findings are hence discussed in the light of extant literature on venture financing as well as entrepreneurial bias literature, to provide insight for both researchers and practitioners in digital entrepreneurship.Background and aims: Perceived stress has been regarded as a risk factor for problematic social networking site (SNS) use, yet little is known about the underlying processes whereby confounding variables may mediate or moderate this relationship. To answer this question, this study examined whether depression and anxiety mediated the relationship between perceived stress and problematic SNS use, and whether these mediating processes were moderated by psychological resilience and social support. Methods: Participants were 641 Chinese college students who completed anonymous questionnaires measuring perceived stress, depression/anxiety, psychological resilience, social support, and problematic SNS use. Results: The results showed that (a) depression/anxiety mediated the relationship between perceived stress and problematic SNS use; (b) the mediating effects of depression/anxiety on the association between perceived stress and problematic SNS use were moderated by psychological resilience. Specifically, the mediating effects of depression/anxiety were stronger for individuals with lower levels of psychological resilience, compared with those with higher levels of psychological resilience; and (c) the mediating effects of depression/anxiety were not moderated by social support, although social support was negatively related to depression/anxiety. Discussion and conclusion: This study can contribute to a better understanding of how and when perceived stress increases the risk of problematic SNS use, and implies the importance of enhancing psychological resilience in preventing problematic SNS use.
