选取1978—2008年中国30个省市的面板数据,运用DEA方法测算中国的全要素生产率及其分解项:技术变化与技术效率,并使用ARDL模型实证分析技术效率和技术变化对就业的影响。研究发现:技术效率无论是长期还是短期都对就业具有显著的抑制效应,但在短期中,技术变化当期对就业没有显著影响;而滞后期技术变化的改善也会对就业人数的增加产生抑制效应,同时,在长期中,技术变化对就业有着显著的促进效应,可以带动就业量的增加。  相似文献

This paper studies the impact of product and labour market structural reforms and the effects of their joint implementation with alternative debt consolidation strategies. The set-up is a dynamic general equilibrium model calibrated for the Greek economy. The results show that structural reforms produce important long-run GDP gains that materialize earlier, the faster the reforms are implemented. When implemented jointly with fiscal consolidations, structural reforms may amplify the short-run costs of fiscal tightening. The GDP dynamics depend on the fiscal instrument used for public debt consolidation. In the long run, however, there are complementarity gains irrespective of the fiscal instrument used.  相似文献

This note considers the competing vertical structures framework with Cournot‐Bertrand competition downstream. It shows that the equilibrium wholesale price paid by a Cournot (Bertrand)‐type retailer is above (below) marginal costs of a corresponding manufacturer. This result contrasts with the one under pure competition downstream (i.e., Cournot or Bertrand), where the wholesale price is set below (above) marginal costs in case of a Cournot (Bertrand) game at the retail level.  相似文献

Entrepreneurial marketing has emerged as a recent perspective within the marketing field, taking the challenges and characteristics of small firms and founding teams into account. Specifically, in the early stages of entrepreneurial marketing, besides potential customers a variety of other stakeholders tend to be in the center of attention. Among these stakeholders, business angels as early-stage investors represent a vital target group. In this paper, we aim to shed light on entrepreneurial marketing in the early phases of new venture creation, in which entrepreneurial firms have an inherent need to market the value of a business opportunity toward potential investors. In particular, we contribute to the literature by introducing the business model as a narrative device for the marketing of early-stage new ventures toward potential business angels. In this regard, the business model is suggested as playing a critical role through making the inherent economic value of a technology explicit. Building on narrative theory, we investigate the role that the business model plays in the decision-making process of 17 business angels. Based on our findings, we propose a model that links the business model to a business angel's interpretation of an investment opportunity and discuss implications for theory and practice.  相似文献

Destination development in China: towards an effective model of explanation   总被引:1,自引:0,他引:1  
This paper addresses the dynamics of the evolution of a nature-based destination in China. Based on longitudinal studies in Zhangjiajie (Hunan Province), it focuses on the roles of institutions in tourism development in China, demonstrating the centrality of institutions and governments in fostering destination development through policy orientations, attracting investments and regulations in their capacity as producers, protectors and promoters of desired processes of change. It describes a five-stage development process from Exploration, through Starting and via Fluctuation and Acceleration to the current stage of Transition leading towards a Destination seeking Better Service Quality. The study, by incorporating institutions as a driving force, develops an RICI model (Resource, Institution, Capital and Innovation) accounting for destination development in China. The key role of policies implemented by local governments and the roles of institutions are critical in the process of its development, especially in the earlier stages, contrasting with many western countries, where the private sector and central government tend to dominate. The paper notes the role of inter-institution rivalries, and the impact of those rivalries on sustainable development. It is suggested that the proposed model could be empirically verified and tested in other cultural or regional destination development contexts.  相似文献
