La Porta showed that there existed a simple linear relationship between corporate valuation and the holding percentage of controlling shareholders. But recent empirical evidence does not support it. A nonlinear relationship is proved between ownership structure and corporate valuaton by relaxing the assumption of La Porta＇s model in this paper. There exists a positive relation between investor protection and corporate valuation. Our empirical research shows that this relation is significantly positive indeed.展开更多

Focus of the analysis is the influence of the specific unification of ownership and control on corporate performance. Findings in the paper are based on research that produced empirical data for Croatia which is subsequently compared with evidence from other Asian and European transition countries facing the same issues. Consequently, transitional ownership structures, influenced by actual privatization process, like emergent corporate governance mechanisms, highly concentrated ownership and undeveloped markets for corporate control are also described. Research findings show that direct or indirect managerial ownership are important phenomena in transition countries, research has also shown that stable and concentrated managerial ownership have positive effects on firms＇ profitability in the observed transitional environments.展开更多

Residents in denser, urban or more transit accessible neighborhoods tend to own fewer cars. Car ownership influences almost all aspects of travel behavior, including travel frequency, travel distances, mode choice and time-of-day choice. At the same time, car ownership affects residential location choices, as households owning cars are less likely to choose urban neighborhoods than households without cars. This paper describes a new microscopic auto-ownership model that has been estimated with survey data. The model is fully integrated with a land use and a transportation model to capture： （1） how owning a car affects travel behavior and location choice; and （2） how the built environment and the transportation needs affect auto-ownership decisions. The model has been validated against census data and is fully operational.展开更多

Using t-test and Logistic regression analysis, we investigated the following aspects: ownership by top managers and the CEO, the number of directors, the percentage of inside directors, CEO duality, and ownership concentration. The empirical tests indicate a lower probability of financial distress when ownership by top managers and that by the CEO are higher. The evidence also shows that a combination of two parts, the CEO and the chairman of the board, may influence the internal control system of a publicly listed companies.展开更多

In order to further promote the deepening of the reform of mixed ownership, this paper randomly selects 200 listed state-owned enterprises as research objects, and studies the trends of the financial performance of these enterprises from the mixed state-owned enterprises and non-mixed-modification enterprises in the five years from 2013 to 2017, and compares their various trends. Financial indicators, a comprehensive evaluation of the problems and causes in the reform of the mixed ownership system, and then propose countermeasures to further deepen the reform of mixed ownership based on the research conclusions.展开更多

The result shows that in general, greater state ownership and less private ownership in a sector will lead to lower water pollution intensity. Test of threshold effect shows that, irrespective of its current level, an increase in state ownership helps improve the environment by different degrees. When pollution intensity is low, ownership diversification helps reduce pollution intensity; when pollution intensity is high, state ownership is the optimal choice for mitigating pollution. This paper's findings suggest that while advancing the mixedownership reform of SOEs, China cannot relax the environmental responsibilities of SOEs, and still less should economic interests override environmental concerns.展开更多

By analyzing the data on automobile ownership and its influencing factors, the learning sample couples for automobile ownership prediction modeling were constructed, and support vector machine (SVM) was used to regression the nonlinear function relation of automobile ownership prediction model, and the established automobile ownership prediction model was used to predict the automobile ownership in different years. To reduce the impact on the accuracy of automobile ownership prediction caused by the large order of magnitude difference between the data of automobile ownership and its influence factors, the normalization method was used to pre-process the automobile ownership and its influence factors, and the inverse normalization was used to process the automobile ownership prediction results. The comparison between the automobile ownership prediction results and the statistical results shows that the automobile ownership prediction model has good generalization performance, and the support vector machine is an effective method to model the automobile ownership prediction.展开更多

Hand hygiene（HH） compliance is regarded as an important indicator of the quality of care in the control of hospital-acquired infections. However, little information is available on whether hospital ownership influences HH compliance. In this study, of 229 hospitals selected from Hubei province in China, 152 were public and 77 were private hospitals. A total of 23 652 healthcare workers（HCWs） were surveyed, using a convenience sampling. HH compliance, the WHO＇s ＂My Five Moments for hand hygiene＂（5 MHH）, among HCWs, together with the factors of hospital ownership, training frequency, bed occupancy rates, etc. were collected. Univariate analysis and ordinal logistic regression analysis were used to analyze factors affecting HH compliance. Overall, HH compliance rates were 67% and 79% for public and private hospitals, respectively. The HH compliance rates of HCWs and 5 MHH were between 55% and 95%, and influenced by hospital ownership（P〈0.05）, excluding compliance rate at the moment after body fluid exposure, and other influence factors included training frequency and bed occupancy rate（P〈0.05）. HH compliance is better in private than in public hospitals. Hospital ownership is a significant factor affecting HH compliance, in addition to training frequency and bed occupancy rate.展开更多

It is a violation of jurisprudence to assign ownership of climate resources. The provisions of local regulation which stipulate that climate resources belong to the state and government therefore has the jurisdiction over the climate probe activities, which is not only counter to higher laws, but also goes against the Constitution. That makes the provisions invalid. Besides, state ownership of climate resources also creates the possibility for the state to take on liabilities for damage caused by climate disasters. The motivation for the above provisions in local regulation is to acquire the administrative approval rights and economic benefits hiding behind those rights. So the basic principles for exercising state power should be in line with basic jurisprudence and conform with provisions of the Constitution and higher laws.展开更多
