中国—东盟自由贸易区产业内贸易结构优化分析

产业内贸易是当今国际贸易发展的主要趋势,对双边贸易结构调整和优化起着重要作用.中国--东盟自由贸易区(CAFTA)作为发展中国家间的最大自由贸易区,影响着东亚以及全球经济格局,产业内贸易发展必将带动双边贸易结构进一步优化.本文运用实证分析方法,对中国--东盟产业内贸易水平及贸易结构进行深入分析.研究结论表明,目前中国--东盟产业内贸易发展水平较低,并且呈现缓慢下降趋势,而以垂直异质为主的产业内贸易结构发展迅速,与产业内贸易发展水平呈现"剪刀差"趋势.     

Do text messages increase voter registration? Evidence from RCTs with a local authority and an advocacy organisation in the UK

In the wake of the Covid-19 pandemic, text messages have become an increasingly attractive tool of voter registration. At the same time, in countries without automated registration, advocacy organisations play a more prominent role in supplementing the efforts of official bodies in registering voters. However, most available, robust evidence on whether voter registration campaigns work is based on campaigns conducted by official bodies charged with electoral registration. We present the results of two RCTs that aimed to increase voter registration in the UK using SMS-text messages, relying mainly on behavioural messaging. One was conducted by a local authority, while the other was implemented by an issue advocacy organisation that had no prior involvement in voter registration. In line with previous findings, the local authority’s text messages resulted in an increased registration rate of eight percentage-points, which translates into a three percentage-point increase in voter turnout. However, the advocacy organisation’s text messages neither increased voter registration, nor turnout, no matter whether the text message offered a personal follow-up conversation, or not. Given that many voter registration campaigns are run by advocacy organisations and text messages are an increasingly important mobilisation tool, this raises questions about the scope conditions of existing findings.
