A study for overviewing language policy and planning research methods

从文献综述中可以看出，语言政策与规划（LPP）研究的研究方法正变得极其多样和复杂。多元化的原因之一是当前LPP的定义有扩大的趋势。不仅官方政府，任何类型的社会团体，如公司、家庭或在线社区，都可以被视为语言规划师。此外，LPP过程被视为交互式协商，而不是利用单向和自上而下的效应。在积累的研究方法中，我们重点关注语言景观、语言管理理论和民族志，并结合三者进行了实地实证研究。对高田obaba地区缅甸餐馆的研究结果表明，不同方法的结合有助于进一步探索语言政策和规划的动态性。

It was clear from the literature review that the research methods of language policy and planning (LPP) studies are getting extremely varied and complex. One of the reasons of the diversification is the current trend of the broadening definition of LPP . Not only official governments but also any kinds of social groups such as companies, families and, or onlinecommunities are able to be viewed as a language planner. Moreover the LPP process is viewed interactive negotiation rather than utilizing one-way and top-down effect. Among accumulated research methods, we focused on linguistic landscape, language management theory and ethnography and conducted an empirical field research combining three of them. Results of the research in Myanmar (Burmese) restaurants in Takadanobaba area showed that the combination of different methods helps to explore the dynamism of language policy and planning in further details.
