Considering both the discrete and ordered nature of the household car ownership an ordered logistic regression model to predict household car ownership is established by using the data of Nanjing Household Travel Survey in the year 2012. The model results show that some household characteristics such as the number of driver licenses household income and home location are significant.Yet the intersection density indicating the street patterns of home location and the dummy near the subway and the bus stop density indicating the transit accessibility of home location are insignificant.The model estimation obtains a good γ2 the goodness of fit of the model and the model validation also shows a good performance in prediction.The marginal effects of all the significant explanatory variables are calculated to quantify the odds change in the household car ownership following a one-unit change in the explanatory variables. 展开更多

In this paper,it investigates the factors affecting successive brand alliance in which two brands from different product categories are featured together to introduce a co-brand.Based on the brand alliance theories,the degree of association,similarity,and complimentary fit between parents brands are important factors in determining successive brand alliance.By using the 5P's,which are premium price,perceived quality,product features,performance,and perceived image,as the measuring scale in brand attributes for each brand,it has reflected the change of brand attributes of the brands before and after brand alliance.400 subjects participate in the research,and 360 of which are valid.From this study,we conclude that when association between parents turns from "-" to "+" and similarity from "-" to "0",there is a trend of descending of co-brand attributes.When fit between parents turns from "-" to "0",there is also a trend of descending of co-brand attributes.While fit between parents turns from "+" to "0",there is a trend of increasing of co-brand attributes.The results show an interesting pattern of interactions among factors,which has important implications for managers in co-brand marketing.These also provide researchers with promising avenues for further study in brand alliance. 展开更多

Property rights have multiple attributes, and these are correlated with national governance. In the West, property rights have the economic function of maximizing efficiency and the political function of rights protection, but in China, they also have a strong social character. With the modernization of national governance, these functions interact with and transform each other. When the state's ability to supply public goods is relatively weak, property rights take on more of a social character, meeting public demand for welfare at the grassroots level. When the state is better able to provide public goods, the social function of property rights lessens as their economic function grows. The social character of property rights was the institutional foundation for China, as a huge agrarian state, to realize "governance through inaction," and at the same time was the secret key that could break the code to the millennial continuity of Chinese agrarian civilization. Reforms including the collectivization of rural property rights after 1949, the "separation of two rights" (to collective ownership and household contracted land, with a focus on the latter), and the "separation of three rights," (to collective ownership, household contracts and revitalized land management). These changes constitute a process in which the economic function of property rights has been growing while their social character has lessened under conditions of national governance modernization. 展开更多
