Since the Third Plenary Session of the 18 th Central Committee of the Communist Party of China, the concept of the mixed ownership economy has received extensive attention from all sectors of society, which has effect on a coming new round of reformation on enterprise property. However, in order to take control of the state-owned shares in the end making the state ownership economy become the principal position and to enlarge the scale of state-owned shares, which guides the common development with the non-public sectors of the economy, how to determine the proportion of state-owned shares? Under the background of the mixed ownership reformation, the article explains the mixed ownership by explaining how to enlarge the state-owned assets controlling scale and how to improve the stateowned company 'economic effi ciency and how to protect the interests of small shareholders. The final conclusion is that the SASAC should use the thinking of relative holdings, instead of the absolute control thinking, and should make use of the games among the large shareholders and the pyramidal ownership structure to make the pattern of ownership diversify. 展开更多

The main objective of the study was to examine the influence of vehicle fleet management practices on service delivery in State-Owned Enterprises (SOEs) in Zimbabwe. The study adopted a pragmatism research philosophy together with a mixed method research paradigm. In addition, structured questionnaires were distributed to 344 respondents drawn from 86 SOEs. Stratified and purposive sampling was used. Descriptive statistics were calculated using Statistical Package for the Social Science (SPSS) version 20. Exploratory factor analysis (EFA) was done on all items of the study while research hypotheses were tested using Structural Equation Modelling (SEM) in AMOS version 21. The study concluded that vehicle maintenance, fuel management, driver management and vehicle replacement positively influence service delivery. In addition, the study also established that Information and Communication Technologies (ICTs) moderate the influence of vehicle fleet management practices on service delivery. The study recommended that there is need for regular driver training and vehicle programs encompassing electronic spares tracking. 展开更多

This paper analyzes the three main fundamental issues in the design of China's ETS pilots,including allowance allocation,price mechanism and state-owned key enterprises,and proposed suggested solutions.For the issue of allowance allocation,we suggest that the gradual hybrid mode could be applied at the beginning,which starts with mainly free allocation and then increases auction ratio gradually.And grandfathering is a suitable method of free allocation.For the issue of price mechanism,we suggest a price floating zone with open market operation to reduce the uncertainty of prices.For the issue of state-owned key enterprises,we suggest a good coordination with SASAC,defining the state-owned property right and supervision right when state-owned key enterprises are involved into the carbon market,and the local government can set rules of allocation and transaction to limit their potential market power. 展开更多

The distribution relationship between the profits of state-owned enterprises and the state has been constantly changing with the times. From the state implementing the policy that state-owned enterprises not pay profits to the state in 1994 to the constant growth of stateowned enterprises in the 21st century,their profits have become more and more abundant. Until 2007,the state issued a document stipulates that the state-owned enterprises should pay part of their profits to the state,but at the initial stage of trial implementation of the policy,the implementation was not effective,and finally in 2010 the state officially announced the collection of profits from state-owned enterprises and increased the proportion of collection. From the perspective of agricultural state-owned enterprises,using the difference-in-difference( DID)model,this paper studied the state policy of increasing the profit delivery proportion of state-owned enterprises in 2020. Through CSMAR database,we selected agricultural state-owned listed companies in the 2008-2013 as samples,tested the impact of the implementation of the new policy in 2010 on the operation performance of agricultural state-owned enterprises,evaluated the implementation effect of the policy through comparing the operation performance before and after the policy,and explored whether the policy has an impact on the bond rating. Through empirical research,it found that increasing the profit delivery proportion of state-owned enterprises is helpful for improving the operation performance of state-owned enterprises and improving the quality of bond ratings,and this policy has more prominent effects on stimulating the performance of monopolistic state-owned enterprises. Therefore,collection of some profits from state-owned enterprises can promote better development of state-owned enterprises and also benefit both the state and the people. 展开更多

In the work, the problems of proper and forced oscillations of dissipative mechanical systems, consisting of rigid and deformable bodies are solved. To quantify the dissipative properties of the system, two values are proposed: the minimum resonance frequency of natural oscillations and the maximum resonant amplitude. In the study of the problem of dissipative inhomogeneous mechanical systems, a nonmonotonic dependence of the damping coefficients on the parameters of the system was observed. The concepts are derived Global damping factor, which characterizes the Damping properties of the dissipative mechanical system as a whole. 展开更多

Seoul’s privately owned public space (POPS) initiative has achieved quantitative success since its introduction in the early 1990s. However, POPSs have been frequently criticized for failing to correspond with the urban context in which they are created and are thus often underused. Association between surrounding urban context and the use of POPS is acknowledged, but specific elements of the urban context associated with the use of POPS and the extent of association are unclear. In this study, the relationship between constituent elements of 48 POPSs including the surrounding ground floor facility use and the use of those spaces in Seoul’s central business district was measured by multiple regression analysis. The results present empirical evidence of a substantial relationship between assembly, mercantile, and business facilities on ground floors of surrounding buildings and the use of POPS. As the surrounding ground floor facility use showed an overriding relationship with the use of POPS that possibly overshadowed the influence of secondary determinants, the 48 POPSs were divided into two groups: those surrounded by commercial facilities and those surrounded by business facilities. The use of POPSs surrounded by commercial facilities was associated with additional variables including the proximity to transit stations and crosswalks. Models using the sample of POPSs surrounded by business facilities were not statistically significant. Based on these results, this paper emphasizes the importance of creating POPSs in connection with desirable surrounding facilities. This study also suggests that anticipation of the usage patterns of POPSs and establishment of guidelines supporting those patterns may be viable by investigating preexisting urban contexts. 展开更多

We theoretically investigate the excited state intramolecular proton transfer(ESIPT) behavior of the novel fluorophore bis-imine derivative molecule HNP which was designed based on the intersection of 1-(hydrazonomethyl)-naphthalene-2-ol and 1-pyrenecarboxaldehyde. Especially, the density functional theory(DFT) and time-dependent density functional theory(TDDFT) methods for HNP monomer are introduced. Moreover, the "our own n-layered integrated molecular orbital and molecular mechanics"(ONIOM) method(TDDFT:universal force field(UFF)) is used to reveal the aggregation-induced emission(AIE) effect on the ESIPT process for HNP in crystal. Our results confirm that the ESIPT process happens upon the photoexcitation for the HNP monomer and HNP in crystal, which is distinctly monitored by the optimized geometric structures and the potential energy curves. In addition, the results of potential energy curves reveal that the ESIPT process in HNP will be promoted by the AIE effect. Furthermore, the highest occupied molecular orbital(HOMO) and lowest unoccupied molecular orbital(LUMO) for the HNP monomer and HNP in crystal have been calculated. The calculation demonstrates that the electron density decrease of proton donor caused by excitation promotes the ESIPT process. In addition, we find that the variation of atomic dipole moment corrected Hirshfeld population(ADCH) charge for proton acceptor induced by the AIE effect facilitates the ESIPT process. The results will be expected to deepen the understanding of ESIPT dynamics for luminophore under the AIE effect and provide insight into future design of high-efficient AIE compounds. 展开更多

The purpose of this study is to analyze the characteristics of the spatial distribution and change trend of the marketing level of stateowned land supply so as to provide policy recommendations. Method of spatial autocorrelation analysis is employed. The results indicate that the spatial layout of the land supply marketing level is generally dispersed,but it does assemble in some specific area. The correlation between the marketing level of state-owned land supply and the economic development is not statistically significant. But their relations fluctuate obviously. The overall marketing level of state-owned land supply is increasing and spatially concentrated. The expansion rate of marketing has decreased first and then increased and stabilized now. The high-value cluster center of marketing level of state-owned land supply exists all over the country; however the existence probability of the cluster is bigger in undeveloped areas. It is concluded that spatial autocorrelation analysis is a good method to quantitatively analyze the spatial variation of marketing level of state-owned land supply in China. To grasp the spatial and temporal variations of the marketing level of state-owned land supply is also good to enhance running of the state-owned land market. 展开更多
