Abstract This study examines changes in legislative support for the governor's legislative agenda in Georgia during the governor's first term in office (1991–94). I analyze the factors that led legislators to support the governor's agenda, as well as how the level of support changed between election years and off‐years. I use multivariate OLS models of gubernatorial support to determine how support varied (1) between the parties, (2) between factions within parties, and (3) over time. I find that there was wide variation in support among factions in the majority party and that support varied widely between election years and off‐years.  相似文献

This paper links the policy context regarding S&T parks to the objectives and characteristics of the established parks and incubators in a relatively small, converging European country. S&T parks and incubators in Greece during the past decade and a half have gradually shifted in terms of ownership and management from university/research institute to the private sector and in terms of financing from public to private funds, also involving the provision of seed capital and access to venture capital. This gradual shift toward more private engagement has created a variety of models out of which, it is hoped, successful innovative companies will emerge in larger numbers than in the past.

This article explores the different and sometimes conflicting explanations of the success of the collective enterprises (town–village-enterprise) in China during the first phase of transition (1979–1995). It is argued that explanations, relying on cultural variables are not sustainable and this for two reasons. First, the importance of the collective enterprise is shrinking while the private sector is clearly on the rise. Second, other factors, referring to characteristics of the local and central political, administrative and economic environment, in which the Chinese enterprise has to (had to?) operate, provide for a sufficient explanation of the peculiar structure of the Chinese collective enterprises. These enterprises are seen as the result of ?bureau-preneurship’ because local bureaucrats were integrated in their management in order to pre-empt predatory behaviour and to facilitate the relationships with the central institutions. The article contributes to the property rights’ theory of the firm as it analyses an empirically very important case in which firms with unclear property rights and structures, apparently not conducive for incentives, might still be the most efficient option.  相似文献
