The indirect effects of foreign direct investment on trade: A network perspective

The relationship between international trade and foreign direct investment (FDI) is one of the main features of globalisation. In this paper, we investigate the effects of FDI on trade from a network perspective, since FDI takes not only direct but also indirect channels from origin to destination countries because of firms’ incentive to reduce tax burden, to minimise coordination costs and to break barriers to market entry. We use a unique data set of international corporate control as a measure of stock FDI to construct a corporate control network (CCN), where the nodes are the countries and the edges are the corporate control relationships. Network measures, as the shortest path length and the communicability, are then computed on the CCN to capture the indirect channel of FDI. Empirically, we find that corporate control has a positive effect on trade both directly and indirectly. The result is robust with different specifications and estimation strategies. Hence, our paper provides strong empirical evidence of the indirect effects of FDI on trade. Moreover, we identify a number of interplaying factors such as regional trade agreements and the region of Asia. We also find that the indirect effects are more pronounced for the manufacturing sector than for primary sectors such as oil extraction and agriculture.     

Work-family conflict and organizational citizenship behavior: the role of job satisfaction and decision authority

Drawing upon the conservation of resources theory (Hobfoll, Am Psychol 44:513–524, 1989), social exchange theory (Blau, Exchange and power in social life, 1964) and the job demand-control model (Karasek, Adm Sci Q 24:285–308, 1979), this study uncovers the theoretical mechanism that explains the relationship between work-family conflict and organizational citizenship behavior (OCB). First, this study focuses on how employee job satisfaction mediates the relationship. Then, we investigate the moderating role of decision authority in the mediated relationship. We employ three-wave data collected from 324 employees in 102 teams to test our hypotheses. Results of hierarchical linear modeling (HLM) first shows that job satisfaction mediates the relationship between work interference with family (WIF) and OCB. In addition, employees’ decision authority moderates the direct effect of WIF on OCB. Specifically, the negative relationship between WIF and OCB is stronger when employees’ decision authority is high. Moreover, decision authority moderates the indirect effect of WIF on OCB via job satisfaction. Specifically, the negative relationship between WIF and job satisfaction is weaker when employees’ decision authority is high. The results suggest that organizations should give employees enough decision authority over their work, as a high level of decision authority may act as a double-edged sword regarding critical organizational outcomes.     

新冠肺炎疫情对中小微外贸企业的影响及对策

突如其来的新冠肺炎对全球经济造成了很大的影响,我国对外贸易当然更是无法幸免。但总体而言,笔者认为,短期影响虽然十分严重,但正在逐步消弭;中期影响需要认真对待,损失基本可控;长期影响更加深刻,但是依然可以化解——我国以及我省对外经济贸易总体向好的态势有望保持。然而,面广量大的中小微外贸企业原本就身体单薄,这场突如其来的疫情,无疑又是雪上加霜,日子更加艰难,亟待关注与帮扶。     

中国国内服务贸易规则体系完善的建议

随着互联网、大数据的发展,国际服务贸易在全球价值链中的地位日益提升,与货物贸易一并构成两大贸易支柱。GATS作为第一部世界服务贸易框架性规则,对服务贸易的发展和顺畅运行做出了巨大贡献,但是其保护程度和开放程度已逐渐难以适应当前服务贸易的发展。多哈回合的停滞不前导致CPTPP等大型自由贸易协定相继产生,使得国际服务贸易规则有了进一步发展。中国服务贸易规则体系是中国调整国际服务贸易关系的法律集合,作为国际贸易法的国内渊源,中国国内服务贸易规则对于适应服务贸易发展现状和衔接国际服务贸易规则有着重要作用,本文即是通过分析国内服务贸易规则的现状及不足,并在借鉴CPTPP的基础上,提出建议。     

中国未来婚姻挤压研究

中国的男孩偏好和对女孩的歧视导致了男性婚姻挤压.在潜在初婚比模型的基础上,使用标准化初婚频率和去进度效应方法设计了两种新的模型,并与现有模型结合,研究中国婚姻挤压状况.在潜在初婚比基础上开发的模型所得到的结论基本相同.2016年到2046年的30年时间里,婚姻市场上男性和女性的潜在初婚比都在1.15以上;2060年之后保持在1.05-1.08水平.从2000年开始,中国会面临严重的男性婚姻挤压,2016年至2046年平均每年过剩男性在120-150万之间,2060年之后每年在50万之下.如果出生性别比得不到有效控制,则未来男性婚姻挤压情况将严重得多.     

电离层闪烁对跟踪测量的影响分析及规避策略

针对某南方卫星测控站测控信号频繁被干扰的情况展开研究。首先介绍国内外对电离层闪烁原理及监视预警方面的研究成果,然后分析电离层闪烁的时空效应原理,通过计算对比电离层强闪烁监测预报数据和卫星测控站的实时观测数据,发现电离层闪烁与卫星测控站跟踪测量信号的幅度、相位抖动以及接收机失锁之间的相关性,最后提出相应的规避策略,期望为后续测控设备的电离层闪烁防护预警研究提供一定的借鉴和参考。

论民事二审程序中原告撤诉权的司法适用——兼与李海涛法官商榷

私权自治并不能证成二审撤诉权的自由行使,《民事诉讼法》第13条、第157条也不能成为二审撤诉权的规范依据。二审撤诉权必须以《最高人民法院关于适用〈民事诉讼法〉若干意见的规定》第191条为适用依据。在原告申请撤诉、被告同意撤诉且生效判决尚未确定等要件之下,方可允许原告撤回起诉,且应通过禁止再诉防止原告滥用诉讼权利。
