Discovering bank risk factors from financial statements based on a new semi‐supervised text mining algorithm

This paper aims to comprehensively uncover bank risk factors from qualitative textual risk disclosures reported in financial statements, which contain a huge amount of information on bank risks. We propose a new semi‐supervised text mining approach named naive collision algorithm to analyse the textual risk disclosures, which can more accurately identify bank risk factors compared with the typical unsupervised text mining approach. We identified 21 bank risk factors in total, which is far more than identified in previous studies. We further analyse the importance of each bank risk factor and how the importance of each risk factor changes over time.     

Economic policy uncertainty and stock price crash risk

This paper studies the impact of economic policy uncertainty on stock price crash risk using data from China. We develop a new index to measure Chinese economic policy uncertainty and find that economic policy uncertainty has a remarkable positive effect on stock price crash risk. However, the effect reverses later. The results also indicate that the positive effect of economic policy uncertainty on stock price crash risk is more prominent for state‐owned enterprises. Moreover, this effect is more prominent for firms with higher information asymmetry and firms with greater disagreement among investors, indicating that economic policy uncertainty affects crash risk through two mechanisms: managers’ concealment of bad news and investors’ heterogeneous beliefs.     

多视角县级空间开发适宜性评价方法对比研究

［目的］随着市县经济社会发展总体规划的改革创新，越发强调主体功能区制度的完善、强化政府空间管控的能力。空间开发适宜性是合理划分国土空间、优化开发布局的重要基础。［方法］研究通过选取了地形地势、交通干线、人口聚集度、经济发展4项适宜性指标和自然灾害影响、可利用土地资源、可利用水资源、生态系统脆弱性4项约束性指标，建立空间开发适宜性评价指标体系，分别从格网与行政区两种视角出发，开展蒲江县级空间开发适宜性评价，采用点对点匹配度分析对两种评价结果进行综合对比分析。［结果］从总体看，蒲江县最适宜区域占比约为4%，较适宜区域占比约为14%，较不适宜区域占比约为15%，最不适宜区域占比约为67%。行政区视角下，各类开发适宜性等级区域差异明显，但街道、乡（镇）行政区内部具有均质性。具体来说，各类开发适宜性等级区有按行政区集聚的趋势，并且其集聚趋势与多指标评价结果关系密切。空间视角下，各类开发适宜性等级跨行政区，街道、乡（镇）行政区内部具有异质性。一方面，各类开发适宜性等级不受行政区影响，局部精准性更高。另一方面，形成跨行政区的开发时序判读，并且这种开发时序多呈现“中心—外围”结构，便于具体指导区域分步开发。［结论］格网尺度可以更精细地反映县级开发适宜性和开发约束性在空间上的差异化分布，提高城镇、农业、生态3类空间范围划定精准性，为合理确定资源开发强度、促进国土空间科学适度有序布局提供技术保障。     

Accounting Standards Harmonization and Financial Integration

We empirically examine whether adopting a uniform set of accounting standards mitigates information frictions in financial markets and facilitates market integration. Using a difference‐in‐difference design, we find that after the mandatory adoption of IFRS local stock returns incorporate more global information and at a faster speed. The effect of IFRS adoption is stronger in countries where there are larger improvements in accounting comparability and for firms with a larger increase in foreign ownership. Overall, our results suggest that accounting standards harmonization facilitates financial market integration.

泸县农村宅基地有偿使用制度改革效果评价

[目的]宅基地有偿使用制度研究有利于推进宅基地制度改革,缓解无偿无限期带来的土地超占乱占和闲置问题。[方法]文章运用层次分析法和模糊综合评价法对2016年和2018年泸县农村宅基地有偿使用制度改革政策效果进行评价。[结果]政策的开展能有效推进村民自治建设进程,但政策的实施要注重公开透明性;有偿使用政策能有效缓解一户多宅、低效闲置、超占乱占等土地浪费现象实现土地的节约集约利用;政策的实施能有效地改善基础设施和农村面貌,但对泸县生产方式转变、新业态发展、农户生活水平提升影响力较小;总体来看农户对有偿使用政策满意度和支持度较高。[结论]针对当前有偿使用制度改革,该文认为宅基地有偿使用制度改革还应该完善有偿使用费收取管理政策,增强政策执行透明度;注重基层队伍建设,实现有偿使用费保值增值;合理选择安置模式,发展农村新业态;加强宅基地有偿使用与有偿退出的高效联动,推进宅基地制度改革进程。
