This article examines non-farm employment in the context of Chinese rural institutional change, based on evidence from discrete-time logistic models for event history analysis using the Life History and Social Change survey. We find the transition to non-farm sector rose rapidly during the Great Leap Forward and market reform, while the Cultural Revolution saw it reach the lowest ebb. While male advantage prevailed exclusively during the Cultural Revolution and early marketization, education possessed a stable positive effect in all historical periods. Although the returns to different kinds of political capital vary along with institutional dynamics, intergenerational reproduction was greatly reduced after the Cultural Revolution.  相似文献

Due to the price elasticity of demand for secondhand commodities, it is difficult to establish a quantitative model for the auction. This paper proposes an agent-based multiattribute reverse auction model to support multicommodity combinatorial auction. First, this paper establishes an agent-based reverse auction model and introduces the framework, procedures, and protocols of the model in detail. Second, in light of the multicommodity environment, the targets, protocols, auction strategies, and approaches are identified. Finally, by using the proposed agent-based auction model, both buyers and sellers will reach simultaneous agreements on the details of the commodities to complete the auction.  相似文献

To enhance the development of academic spin-offs, surrogate (external) entrepreneurs are often added to the entrepreneurial team comprising academics. Existing research focused on entrepreneurial team diversity (horizontal member differences) and has mixed results. Vertical member differences (i.e., inequality) between academics and non-academics are not addressed. However, strategic decision making is one of the main responsibilities of an entrepreneurial team. Decision-making power, as reflected in ownership, in particular, is thus of the essence. Based on a sample of 164 Italian academic spin-offs, this article investigates the impacts of both horizontal and vertical heterogeneity of entrepreneurial teams on the firms’ performance. The findings confirm that surrogate entrepreneurs generally make a positive contribution to academic spin-off performance but become counter-productive when their presence overpowers that of academics.  相似文献
