Public Health"],"abstract":"<jats:p>Rural-to-urban migration has increased rapidly in China since the early 1980s, with the number of migrants has reached 376 million by 2020. Despite this sharp trend and the significant contributions that migrants have made to urban development, the migrant workers have had very limited access to the social insurance that the majority of urban workers enjoy. Against the background of the social insurance system adjustment in Chengdu in 2011, this study uses a difference-in-differences (DID) model to empirically test the impacts of changes in the social insurance policy contribution rates on the social insurance participation rates of migrant workers, using the China Migrants Dynamic Survey (CMDS) data for 2009\u20132016. We find that the social insurance participation rate of migrant workers was significantly reduced after they were incorporated into the urban worker insurance system. There was no significant change in the wages of migrant workers, but the working hours were increased and their consumption level decreased. In other words, simply changing the social insurance model of migrant workers from \u201ccomprehensive social insurance\u201d to \u201curban employee insurance\u201d reduces the incentives for migrant workers to participate in insurance and harms the overall welfare of migrant workers. Our study indicates that the design of the social security policy is an important reason for the lower participation rate of migrants. It is necessary to solve the problem of insufficient incentives through the targeted social security policies; primarily, the formulation of a social security policy contribution rate suitable for the migrants, and the establishment of a comprehensive social security policy and the gradual integration of the social security system.<\/jats:p>","DOI":"10.3389\/fpubh.2021.736340","type":"journal-article","created":{"date-parts":[[2021,10,21]],"date-time":"2021-10-21T06:19:15Z","timestamp":1634797155000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":13,"title":["Institutional Design and Incentives for Migrant Workers to Participate in Social Insurance in China: Evidence From a Policy Experiment in Chengdu City"],"prefix":"10.3389","volume":"9","author":[{"given":"Yihao","family":"Tian","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuxiao","family":"Chen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mei","family":"Zhou","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shaoyang","family":"Zhao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2021,10,21]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"37","DOI":"10.19625\/j.cnki.cn44-1338\/f.2004.06.006","article-title":"Marginalized migrant labor force","volume":"6","author":"Cai","year":"2004","journal-title":"Open Herald."},{"key":"B2","first-page":"2","article-title":"Development and challenges of social insurance for China's migrant population in the 30 years of reform and opening up","volume":"5","author":"Zheng","year":"2008","journal-title":"Chin Popul Sci."},{"key":"B3","doi-asserted-by":"publisher","first-page":"1195","DOI":"10.1016\/j.chieco.2012.09.002","article-title":"Labor contracts and social insurance among migrant workers in China","volume":"23","author":"Gao","year":"2012","journal-title":"China Econ Rev."},{"key":"B4","doi-asserted-by":"publisher","first-page":"711","DOI":"10.1111\/bjir.12056","article-title":"How does China's new labor contract law affect floating workers?","volume":"53","author":"Li","year":"2015","journal-title":"Br J Ind Relat."},{"key":"B5","article-title":"Analysis of migrant workers' social security issues and policy suggestions","author":"Luo","year":"2007","journal-title":"Int Forum Build Harmon Soc Soc Insur."},{"key":"B6","first-page":"11","article-title":"Analysis of the changes and perfection of the path choice of China's endowment insurance system from the perspective of state-owned enterprises","volume":"4","author":"Wu","year":"2002","journal-title":"Theor Guide."},{"key":"B7","doi-asserted-by":"publisher","first-page":"8","DOI":"10.19632\/j.cnki.11-3953\/a.2007.06.003","article-title":"Social security issues of China's migrants population","volume":"6","author":"Zheng","year":"2006","journal-title":"Theor Vision."},{"key":"B8","first-page":"100","article-title":"Public thinking on social insurance of migrant population","volume":"5","author":"Cao","year":"2007","journal-title":"Northwestern Populat."},{"key":"B9","first-page":"111","article-title":"Analysis of the social security issues of China's migrants population","volume":"6","author":"Tong","year":"2010","journal-title":"Sci Technol Bus Monthly."},{"key":"B10","doi-asserted-by":"publisher","first-page":"185","DOI":"10.19387\/j.cnki.1009-0592.2017.04.227","article-title":"The current situation of social security for migrant population in China and countermeasures","volume":"11","author":"Li","year":"2017","journal-title":"Legal Syst Soc."},{"key":"B11","first-page":"209","article-title":"Dangers of fragmentation system in China's social insurance and the origin of fragmentation impulse","volume":"1","author":"Zheng","year":"2009","journal-title":"Social security research."},{"key":"B12","first-page":"81","article-title":"Analysis of regional differences in the status of migrants' social insurance participation\u2014based on the 2011 migrants survey of 32 provincial units across China","volume":"2","author":"Wei","year":"2013","journal-title":"Populat J."},{"key":"B13","doi-asserted-by":"publisher","first-page":"61","DOI":"10.16405\/j.cnki.1004-129X.2016.01.006","article-title":"Research on the influencing factors of social security participation rate of urban migrants population\u2014analysis based on dynamic monitoring data of migrants population in Beijing-Tianjin-Hebei","volume":"38","author":"Han","year":"2016","journal-title":"Populat J."},{"key":"B14","doi-asserted-by":"publisher","first-page":"230","DOI":"10.1016\/j.chieco.2007.06.002","article-title":"Who bears the burden of employer compliance with social security contributions?
