为了探寻开发区主要信访事项以及疑难案件的成因,探索更有效地解决开发区信访维稳工作成效的途径,2012年8月至2013年8月,笔者对西安某开发区信访人展开了问卷调查和个别访谈,并结合三年来与上访人谈判的工作实践,进一步了解了有关情况。基于这些调研工作的基础材料,本文进行了统计分析,概括了主要信访事项及疑难案件的成因,有针对性地提出了可行性对策。 In order to find out the causes of the major letters and visits in the zone and the causes of difficult cases and to explore ways to effectively address the effectiveness of the letters and calls in the zone, from August 2012 to August 2013, the author conducted a questionnaire survey on letters and visits from a development zone in Xi’an Individual interview, and combined with three years of work experience with the petitioners to negotiate further understanding of the situation. Based on the basic materials of these research work, this paper makes a statistical analysis, summarizes the causes of the major petitions and difficult cases, and proposes feasible measures.
