把上市公司按照所有制结构类型分为国有控股上市公司和民营上市公司,利用倾向得分匹配方法(PSM)和回归分析实证研究了上市公司总经理更替模式对公司业绩的影响,结果发现:(1)国有控股和民营上市公司总经理更替模式对公司业绩影响程度不同;(2)国有控股上市公司总经理内部提升相对于外部聘任更能提升公司业绩,而民营上市公司内部提升或是外部聘任对公司业绩影响相近,没有明显区别;(3)无论是国有公司还是民营公司,总经理更替在短期内的负向影响要大于长期。最后,为了降低总经理更替对公司业绩的负面影响,提出了对策建议。

Electrocatalytic production of hydrogen peroxide(H_(2)O_(2))via the 2e^(-) transfer route of the oxygen reduction reaction(ORR)offers a promising alternative to the energy-intensive anthraquinone process,which dominates current industrial-scale production of H_(2)O_(2).The availability of cost-effective electrocatalysts exhibiting high activity,selectivity,and stability is imperative for the practical deployment of this ***-atom catalysts(SACs)featuring the characteristics of both homogeneous and heterogeneous catalysts are particularly well suited for H_(2)O_(2) synthesis and thus,have been intensively investigated in the last few ***,we present an in-depth review of the current trends for designing SACs for H_(2)O_(2) production via the 2e^(-)ORR *** start from the electronic and geometric structures of ***,strategies for regulating these isolated metal sites and their coordination environments are presented in detail,since these fundamentally determine electrocatalytic ***,correlations between electronic structures and electrocatalytic performance of the materials are ***,the factors that potentially impact the performance of SACs in H_(2)O_(2)production are ***,the challenges and opportunities for rational design of more targeted H_(2)O_(2)-producing SACs are *** hope this review will present the latest developments in this area and shed light on the design of advanced materials for electrochemical energy conversion.
