我国市场经济改革和经济发展的首要任务是农村的货币化和城市化,"三农问题"是当前我国经济结构中最重大的问题.在我国经济高速发展的同时,我国经济也存在着沦为"富人经济"的巨大风险.在这个问题上,提高农业劳动生产率和发展乡镇企业都不能从根本上解决问题,只有通过城市化、通过高速发展的经济来迅速转移农村剩余劳动力,实现农民市民化、农业工业化才能解决"三农"问题,才能使我国经济健康运行. 相似文献

The study of climatic variables that govern the Indian summer monsoon has been widely explored. In this work, we use a non-linear deep learning-based feature reduction scheme for the discovery of skilful predictors for monsoon rainfall with climatic variables from various regions of the globe. We use a stacked autoencoder network along with two advanced machine learning techniques to forecast the Indian summer monsoon. We show that the predictors such as the sea surface temperature and zonal wind can predict the Indian summer monsoon one month ahead, whereas the sea level pressure can predict ten months before the season. Further, we also show that the predictors derived from a combination of climatic variables can outperform the predictors derived from an individual variable. The stacked autoencoder model with combined predictors of sea surface temperature and sea level pressure can predict the monsoon (June-September) two months ahead with a 2.8% error. The accuracy of the identified predictors is found to be superior to the state-of-the-art predictions of the Indian monsoon. 相似文献

A resilience-based framework for evaluating adaptive co-management: Linking ecology, economics and society in a complex world 总被引:4,自引:0,他引:4
Adaptive co-management brings together collaborative and adaptive approaches in pursuit of sustainable resource use and social-ecological resilience. Enthusiasm for this management approach, however, is countered by recent critiques regarding outcomes. A lack of evidence from consistent evaluation of adaptive co-management further exacerbates this situation. This paper revisits the issue of evaluation in natural resource management and recasts it in light of complex adaptive systems thinking. An evaluative framework for adaptive co-management is developed which directs attention toward three broad components: ecosystem conditions, livelihood outcomes and process and institutional conditions. Scale-specific parameters are offered for each component to facilitate systematic learning from experience and encourage cross-site comparisons. Conclusions highlight the importance of systematically incorporating evaluation into the adaptive co-management process and recognize the challenge for resource agencies and researchers to shift from a conventional to a complex adaptive system perspective. 相似文献

Summary. According to empirical studies, the wage differential by skills evolved non–monotonically in the past decades although the
relative supply of skilled labor steadily increased. The present paper provides a theoretical explanation for this finding.
In our setting, technological change intertemporally alters the human–capital investment incentives of heterogeneous individuals.
As a consequence of changing incentives, the time path of the relative wage is U–shaped while there is a rise in the share
of skilled workers.

Double Moral Hazard,Monitoring, and the Nature of Contracts 总被引:8,自引:0,他引:8

generalized double-sided moral-hazard model, with risk-averse parties who mutually monitor each other (to get a reasonable idea of outcome/effort).
The model considers trade-off between monitoring costs and moral hazard costs, which are endogenously determined by the extent
of monitoring.
Using this model, we formally prove a generalized version of Coase's conjecture – that the optimal contract minimizes the
agency and risk costs. We then show how varying assumptions about the feasibility or cost of monitoring of the outcome or
the worker's effort lead to different contracts being optimal. The analysis is then used to explain the nature of contracts
observed in practice under many different situations. We will give an explanation as to why industrial workers typically work
under wage contracts, while share contracts are common in agriculture and will explain why profit sharing is more common for
senior managers than for the production workers.
