Effect of Migration on Children＇s Self-esteem in Rural China

China＇s rapid economic growth has been facilitated by its large volume of rural to urban migration. China ＇s projected future development, especially increasing urbanization, implies that such migration will further intensify. However, migration does not come without cost. There are concerns about the potential negative impacts of migration on children＇s care, education, and, in particular, the self-esteem of children left behind in villages where one or both parents have out-migrated to cities. In this paper, we employ unique survey data collected from Shaanxi Province, where more than 4700 ninth grade students from 36 rural junior high schools in five counties were surveyed in late 2011. The results show that having both parents migrate into cities significantly reduced children ＂s self-esteem. The effects are also gender sensitive. Girls that had a father or both parents who had out-migrated were inclined to have lower self-esteem than boys. Moreover, our study findings indicate that parental migration decreased children ＂s self-esteem more for individuals with initial low self-esteem.

Different Roles of Land in Rural-Urban Migration： Evidence from China＇s Household Survey

This paper explores the influence of land holding on rural–urban migration using China's 2008 household survey data. It shows that the contradictory findings of existing published literature can be explained by introducing a migration distance variable. The empirical studies show that land holding plays a different role in short‐distance and long‐distance migration. Land holding has a U‐shaped curve association with the probability of short‐distance migration and has an inverted‐U‐shaped association with the probability of long‐distance migration. Therefore, the government needs to provide more job information and migration subsidies to farmers who have little land to overcome difficulties in the process of migration so as to reduce rural–urban inequality.     

Migration and its Determinants: A Study of Two Communities in Colombia

Using data gathered by the author in two communities in Southwestern Colombia, this paper tests a model of migration which incorporates relative deprivation as one of many possible reasons to migrate. The study finds that the product of relative deprivation and family income not only has a sensible interpretation; it is a better predictor of migration than its two component variables alone. Results also show that families with the highest propensities to migrate are those with the most to gain in terms of being better able to reduce relative deprivation through successful migration. These families, however, are neither at the bottom nor at the top of the income distribution in their communities. The study also finds that those most likely to migrate to the USA conform most closely to the immigration policies of the USA.

The impact of migration on the cross‐border M&A: Some evidence for Japan

Facing the rapidly ageing society and shrinking of markets at home, Japanese firms are expanding outbound mergers and acquisitions (M&A) activity at a record pace. This study examines the determinants of Japanese cross‐border M&A activity focusing on the role of migrant networks in overcoming the informational barriers to such activity. Migrants include immigrants residing in Japan as well as Japanese citizens residing abroad. Our results suggest that the presence of immigrants and of Japanese citizens residing abroad both increase the probability of acquiring assets in a potential target country. Moreover, both communities exert positive effects on the number and value of outbound M&A deals.     

地方财政支出、人口迁移与房价

本文基于中国267个地级及以上城市2009—2018年面板数据,运用联立方程模型探讨公共支出不断增加的背景下,地方财政支出、人口迁移与房价的关系。研究结果显示：地方财政支出的增加推动人口迁移,且短期作用更加明显;人口迁移对房价具有正向影响,但影响不具有持续性;地方财政支出对房价的资本化作用明显,且存在正向累加作用。基于此,本文提出推动城市间公共服务均等化、建立稳定的住房市场和推进房产税征收进程的建议。

地震资料叠前深度偏移处理质量控制

叠前深度偏移处理目前已广泛应用于地震勘探资料处理中,被认为是解决复杂地质构造正确成像困难问题较好方法,但其处理成果同时又受多种因素影响,需要在资料处理过程中加以控制。通过分析这些影响因素,提出消除或削减这些影响的方法,达到正确还原地层构造形态的目的。
