数字技术变革已经成为企业高质量发展的重要助力.利用“两化融合”试点这一准自然试验并以2007–2021年我国制造业上市公司为样本,本文采用多时点双重差分法考察数字技术变革对企业股价崩盘风险的影响.结果发现:1)随着“两化融合”试点大幅促进企业数字技术变革,企业未来的股价崩盘风险显著下降,这一结论进一步得到了一系列稳健性检验的支持. 2)机制分析揭示,“两化融合”试点通过提升内部控制质量降低了企业未来的股价崩盘风险,在此过程中并未吸引更多的外部监督. 3)当会计稳健性差、盈余激进度高、分析师跟踪少以及媒体关注度低时,“两化融合”试点降低股价崩盘风险的效应更显著,可见新兴数字技术与传统治理机制存在一定的互补作用.本研究丰富了数字经济支持上市公司治理改善的经验证据和作用路径,所得结论为推动数字治理提升上市公司质量提供了决策参考.

基于目标置换效应,深入分析社会组织的项目运作过程后发现,社会组织疲于完成项目的量化指标,服务对象的需求被考核指标和项目委托方的需求所置换,在项目运作中普遍存在形式置换内容的行为,体现出重形式、轻内容,重文档、轻服务,服务活动化与娱乐化,服务随意化与碎片化,服务对象同质化与重复化等目标置换特征。项目设计欠缺需求调研,目标设置偏重量化指标,在执行中缺乏双向沟通机制,外部监管采用重文档、重财务的评价方式,致使社会组织为迎合评估而弱化服务成效,因缺乏资源与人才而难以进行专业化发展,出现各种目标置换问题。要破解社会组织项目运作中的目标置换问题,就需要在项目发包前进行科学的事前评估,减少合同中严格的量化指标,加强双向沟通机制建设,强化服务成效评估,以及加强社会组织专业化服务建设。

China & World Economy 2007年第6期15卷 87-103页

This paper uses 4-digit SITC data to identify groups of manufactured goods exported from China to the USA that have strong or rising comparative advantages. We find that most of the trades are inter-industry, with only a small portion being vertical intra-industry trades （IIT）. Our results confirm that Sino-US trade is complementary. We construct an imbalanced index of IIT, and identify the goods groups that aggravate and reduce the US trade deficit with China. We suggest an approach for calculating a dynamic IIT index that might mitigate the aggregation bias of the existing methodologies. Our improved index reveals that the dynamic imbalances of US-Chinese IIT in manufactured goods are worse than their static IIT imbalances, which means that it would be difficult to correct the deficit of US trade with China in the following couple of years. Adjusting and improving the structures of industries and products is China ＇s major task for sustainable trade growth.

The aim of this study was to explore the optimal timing of holmium laser enucleation of the prostate(HoLEP)in patients presenting benign prostatic hyperplasia(BPH)with lower urinary tract symptoms(LUTS).A retrospective analysis was conducted based on the perioperative and postoperative outcome data of 1212 patients who underwent HoLEP in shanghai Ninth People’s Hospital(shanghai,China)between January 2009 and December *** to the preoperative International Prostate Symptom Score(IPSS),all patients whom we analyzed were divided into Group A(IPSS of 8–18)and Group B(IPSS of 19–35).Peri-and postoperative outcome data were obtained during the 1-year *** changes were the main postoperative *** postoperative IPSS,quality of life,peak urinary flow rate,postvoid residual,and overactive bladder symptom score(OABSS)improved *** IPSS improved further in the group with severe LUTS symptoms,but the postoperative IPSS was still higher than that in the moderate LUTS *** showing moderate and severe cases after follow-up were more frequent in Group B(9.1%)than in Group A(5.2%)(P<0.05).There were no significant intergroup differences in the intraoperative American Society of Anesthesiologists or hospitalization expense scores,and the medication costs,as well as the total costs,were significantly higher in Group *** this retrospective study,HoLEP was an effective treatment for symptomatic *** patients with LUTS,earlier surgery in patients with moderate severity may result in a marginally better 12-month IPSS than that in men with severe symptoms.

以2001—2014年我国A股上市公司为样本,研究信贷供给通过财务柔性价值对企业绩效产生的影响,以及考虑财务柔性价值的信贷所有制歧视问题。结果发现:信贷供给对业绩的作用受财务柔性价值的影响,企业的财务柔性价值越高,信贷供给对业绩的作用越显著;对于财务柔性价值最高的企业,确实存在信贷所有制歧视问题,即同等财务柔性价值下,信贷对国有企业业绩的作用更显著,而信贷对业绩的作用在规模上无差异。

目的:调查乳腺癌生存者的经济毒性现状,并分析其影响因素。方法:采用方便抽样方法,应用一般资料调查表、慢性病治疗经济毒性功能评估综合评分量表、心理弹性量表、领悟社会支持量表和***症状评估量表,于2021年6月-10月对上海市徐汇区3家社区卫生服务中心和1个患者团体组织的乳腺癌生存者进行横断面调查。结果:共纳入312名乳腺癌生存者,其经济毒性得分为(22.70±8.39)分。多元线性回归结果显示,乳腺癌生存者的年龄、受教育水平、化疗、独居、个人月总收入、家庭可支配存款、心理弹性、症状困扰程度是经济毒性的影响因素,可解释总变异的28.5%。结论:经济毒性在乳腺癌生存者中普遍存在,影响其生活质量。除人口学因素外,心理弹性、症状困扰程度与癌症相关经济毒性存在关系,这为今后开发针对经济毒性的干预策略提供了新的视角。
