中国地方政府绩效评估中的绩效维度:现状与未来——基于德尔菲法的研究

对绩效的认识是确定政府绩效评估内容的基础,而评估内容往往反映了对不同绩效维度的使用。本文应用德尔菲法,对当前地方政府绩效评估中各种绩效维度的使用情况进行系统描述,并对其未来可能的发展趋势进行预测。分析表明,目前各地政府偏重于用"关键议题是否解决"来衡量政府绩效,以GDP为代表的"正式的效果"被普遍而且优先使用;而在未来三年中,各种绩效维度的使用均会得到不同程度的加强,各个维度的使用情况将可能不再存在显著差异,总体上会向着评估内容逐渐全面、区域之间逐渐统一的方向发展。

绩效信息是政府绩效评估的关键因素。应用德尔菲法,通过对8类利益相关者感知绩效信息来源和8类部门或文件等非感知绩效信息来源使用情况的专家调查,研究了中国地方政府绩效评估中信息来源的现状。研究发现政治家是目前使用最为广泛的绩效信息来源,而来自于政府系统外部的感知绩效信息在目前使用相对较少。从总体上来看,目前非感知绩效信息来源在政府绩效评估中居于主体地位。

在以往关注不同类型创新行为对组织绩效影响的研究中,组织氛围与沟通、人力资源与管理和行政成本是三类较为常见的影响因素,但三者尚未综合形成统一的框架。本研究选取了领导干部任前公示这一以人力资源管理为内容的创新行为,构建了三因素影响组织绩效的过程假设。通过分析问卷调查数据,发现三因素之间存在显著的相关性,且若按照组织边界划分绩效内容,三因素均与组织的内部成长建设绩效显著相关,而同组织外部绩效水平相关程度较弱。依此认为,创新行为影响绩效是一个由人、财、物三因素互动,并依据创新本身特点内容有所侧重的过程。

An extract (G-INH) made from mature human granulocytes freshly isolated from normai blood causes human neutrophils to undergo apoptosis in vitro as shown by morphologic changes and by the typical ladder pattern of small DNA fragments noted on agarose gel electrophoresis of isolated DNA. Apoptosis occurs in from 20% to 30% of neutrophils over 24 hours of culture in vitro and the addition of G-INH to the medium causes a dose-related increase in the incidence of apoptosis. Heating G-INH at 60t for 30 minutes does not destroy its capacity to induce apoptosis but GM-CSF, G-CSF, and to a lesser extent IL-1β, antagonize this action. IL-3 does not diminish G-INH induced apoptosis of neutrophils. Substances, released from, mature neutrophils may participate in regulating the survival of other neutrophils, particularly in sites where the cells are in close proximity as in the marrow. Self destruction of post-mitotic neutrophils in marrow may thus represent an-other level at which regulation of cell production

文章用德尔菲法,通过对地方政府绩效评估中19种利益相关者和16种绩效数据使用情况的调查,研究了地方政府绩效评估活动中利益相关者与绩效数据的现状和相互关系。研究结果表明,利益相关者和绩效数据之间呈现简单的线性关系,呈现出"一荣俱荣,一损俱损"的局面。研究还发现在现阶段绩效评估中更多关注的是政府内部利益相关者的诉求,更多使用的是政府内部绩效数据来判断政府绩效好坏。该研究对上述发现内在原因进行了分析,并提出未来改进的建议。

如果把你一天的生活按照情节来划分,你更喜欢它是爆笑喜剧片、鬼马科幻片,还是慢动作的文艺片?告诉你,其实它是不折不扣的"恐怖片"。别急着否认,从你清早睁开双眼的那一刻起,如影随形的"恐惧"就跟着你开始了一天的旅行……努力睁开重重的眼皮,你发现这时的房间已经被阳光照了个透亮。"要迟到了!"你一个激灵从床上跃起,飞速抄起手边的闹钟,这才猛然想起来——今天是周六,不用上学。和迟到的恐惧说声"早上好"吧,因为每天叫你起床的不是闹钟,而正是这种恐惧。并且它似乎具有惯性,常常搅了你赖床的美梦。
