上市国企高管薪酬业绩敏感性结构化解析
Research on Executive Pay Performance Sensitivity Structure of Chinese State-Owned Listed Companies
 [PDF]

,
Finance (FIN) , 2016, DOI: 10.12677/FIN.2016.62008
Abstract:
本文以2006~2013年1001家国有上市公司为样本,通过动态面板数据构建多元回归模型对国有企业薪酬业绩敏感性结构化差异进行实证检验,比较了中央控股国有企业和地方控股国有企业在薪酬业绩上的不同表现,及国企高管业绩敏感性在行业上的差异。研究发现:(1) 我国国有上市公司高管薪酬与业绩存在相关性,但其薪酬业绩敏感性显著低于非国有上市公司;(2) 国有上市公司中,央企高管薪酬业绩敏感性显著低于地方国企;(3) 金融行业国有上市公司管理层的薪酬业绩敏感性显著低于其他行业。实证结果有助于明确未来国企薪酬改革政策的指向性,本文据此提出了多层次治理建议,对国企薪酬制度的进一步完善具有参考意义。
In this paper, the sample of the models includes 2561 China’s state-owned listed companies from 2006 to 2013 (including the 1001 state-owned listed companies). By constructing the panel data regression models, this research compares the difference between the executive pay performance sensitivity of central state-owned enterprise and that of local state-owned enterprises, as well as the difference of executive pay performance sensitivity of state-owned financial institutions and state-owned non-financial institutions. The study result shows that: (1) there is a significant cor-relation between the executive pay and company performance of China’s state-owned listed com-panies, but the executive PPS of state-owned listed companies is evidently lower than that of non- state-owned listed companies. (2) Executive PPS of central state-owned companies was significantly lower than that of local state-owned companies. (3) Executive pay performance sensitivity of state-owned financial enterprises was significantly lower than that of state-owned non-financial enterprises. When it comes to policy on executive compensation regulation of state-owned enter-prises, items should also be more targeted. This study offers reference for further optimization for executive performance appraisal system in state-owned companies.

Abstract:
针对拍摄的食物照片的后处理需求,现有方法不适用的问题,提出了一种食物图像的色彩增强算法。该算法采用HSI和HSV两种颜色空间联合处理,利用设计的饱和度矫正曲线和符合食物色彩特征的色调参数曲线做加权矫正,以及设计的亮度矫正曲线处理。该算法针对于食物图像的色彩增强,弥补了食物色彩增强算法方面的空缺。实验结果表明,该方法可以大大提高食物图像的主客观质量。本文提出的食物图像的色彩增强算法,针对食物色彩特征进行设计,采用两种颜色空间联合处理,得到适用于食物图像的增强效果。
Because the conventional methods are not suitable for the post-processing of food image, we pro-pose a color enhancement algorithm in food image. The algorithm is processed in HSI and HSV color space, using designed correction curve of color saturation with parameter curve of hue, which corresponds to the feature of food image, and uses designed correction curve of brightness. This algorithm is targeted at color enhancement of food image and fills the blank of color enhancement algorithms in food image. Experimental results show that the algorithm can greatly improve the subjective and objective quality of food image. The color enhancement algorithm in food image that we proposed is designed with the characteristics of food image, combined with the use of two color spaces, to get an enhancement result which is suitable for food image.
黔南宾夕法尼亚亚纪珊瑚礁相腕足动物氧同位素组成及其古水温信息

沉积学报 , 2011,
Abstract: 黔南宾夕法尼亚亚纪Triticites带内大型Fomitchevella珊瑚礁群落中见附礁生长的腕足动物Striatiferastriata和Enteletoidesshuichengensis,XRD测试结果显示Striatiferastriata壳体次生层为保存较好、成分纯净的低镁方解石,完全未受到成岩作用改造;Enteletoidesshuichengensis壳层中则含少量Fe、Ni,可能与成岩作用改造有关。两种腕足动物壳体横切面同一生长带棱柱层中的Ni、Fe、Mn、Na、Sr呈对称性分布,表明这两个种壳体原始信息保存良好,可忽略成岩改造对Enteletoidesshuichengensis壳体的影响。测得Striatiferastriata和Enteletoidesshuichengensis壳体棱柱层中的δ18OPDB分别为-3.249‰和-3.385‰,据此推算出古海水温度为21.60~31.18℃。腕足动物壳体具有较高的δ13CPDB值,分别为4.784‰,4.782‰。利用碳氧同位素分析结果计算得到Z值接近135,表明珊瑚礁区古海水盐度正常。

城市土地价值增值的原因及收益分配探微

财会月刊 , 2007,
Abstract: 本文运用经济学理论对城市土地价值增值的本质进行了剖析,结合目前我国城市土地增值收益回收分配中存在的问题,从税费体系建设、土地增值计价及政府管理等方面提出了城市土地增值收益分配的改进思路。【关键词】城市土地地租增值收益分配随着我国城市化进程的加快,城市土地使用效益明显提高,城市土地增值收益分配问题便显得愈来愈突出。因此,从本质上分析城市土地价值增值的来源,厘清其增值收益分配过程中存在的问题,对于优化城市土地利用结构和效率,充实城市建设资金具有重要的意义。  一、城市土地价值增值的原因及其经济学机理  1.城市土地价值增值的原因。①供求性增值。随着社会的发展,城镇人口逐渐增多,人类对土地需求日益增大,造成城镇建设用地供不应求从而引起的土地增值。②投资性增值。政府对城市基础设施和公共设施等进行投资改造和地产商进行房地产开发导致地价上涨、土地增值。③用途转变性增值。由于城市规划变化,使土地利用条件、利用类型发生改变,如由工业用地转变为商业、金融用地,由住宅用地转变为商业用地等,这种土地用途的转变产生了土地增值。

技术创新对产业演进的影响――基于模块化系统的产品创新阶段分析

科技进步与对策 , 2008,
Abstract: 在以模块化为特征的产业中,产品创新引导产业演进,创新影响企业的进入与退出。在产品创新中,对在位者的分析应考虑代际范围经济和资源转换成本。新厂商可采取产品创新、模仿创新以及利用分裂技术等方式进入。创新技能、模块化程度、沉没成本和市场环境等将影响新厂商的进入。创新竞争的结果,使核心模块市场结构趋于竞争性垄断,一般模块和系统的装配市场则日趋竞争,企业间网络得以大力发展。以模块化为特征的产业资源转换成本代际范围经济
