以创新效率评价作为切入点,着重分析不同行业领域企业研发机构创新效率评价核心指标的选择问题。研究发现:效率评价指标体系的设定对于不同行业领域企业研发机构最终的评价结果会产生直接的影响,其中,高学历人员等人力资源类指标对劳动密集型行业效率影响较大;经费支出等财力物资类指标对资本密集型行业效率影响较大;有效发明专利等创新成果类指标对技术密集型行业效率影响较大;而新产品产值等经济效益类指标对于三大类行业效率均有明显影响。  相似文献

本文对我国对外直接投资的逆向技术溢出效应进行分析评价,研究表明对外直接投资对我国技术水平的提升有显著的促进作用,并且存在较大的地区差异,对外直接投资对东部地区技术水平的提升作用明显大于中西部地区。同时人力资本积累在此过程中的作用不显著。因此加大政府的扶持力度,更加注重吸收国际创新型人才,增加研发投入是我国提升对外直接投资逆向技术溢出效应的关键。  相似文献

Since the 1970s, several Southeast Queensland coastal towns in areas marketed as the ‘Gold Coast’ and the ‘Sunshine Coast’ have merged with each other and joined with Brisbane to become one of the world's longest urban coastal strips. The population of this 200 km long city is fast approaching three million. This urban pattern reflects the preferences of many Australians about where and in what type of housing they would like to live. The unplanned nature of this growth raises several policy challenges relating to resource use and traffic congestion.  相似文献

In a two‐sector model, where one of the sectors is monopolistically competitive and subject to increasing returns to scale but without love for variety, we analyse the effects of a balanced budget fiscal expansion. Such an expansion could increase the welfare of the representative individual, if elasticities of substitution in production and consumption are low. A reorganization of production takes place—increasing returns enabling a rise in real income.  相似文献

Europa sufre desde el decenio de 1970 una crisis crónica del empleo que ha cobrado dimensiones sin precedentes con la crisis económica actual. Para comprenderla, la autora hace un balance del diálogo social y de los pactos sociales sobre reformas laborales y de los regímenes de pensiones, evalúa las políticas activas de mercado de trabajo y analiza las economías resilientes; concluye demostrando la necesidad de reinventar el diálogo social y la protección social teniendo en cuenta las transformaciones socioeconómicas actuales, reorientar el crédito hacia las PYME, activar la demanda de trabajadores y coordinar las políticas macroeconómicas a escala internacional.  相似文献

The paper attempts to examine whether there is regional convergence of per capita consumption, inequality and poverty across various states in India. Using panel unit root tests that are robust to cross-sectional dependence, we find that inequality and poverty indicators converge at both rural and urban levels. Further, per capita consumption converges at urban level but not at rural level. Based on factor analysis, we find two groups of states for rural sectors, viz., low-growth and high-growth states, for each of which per capita consumption converges. We also attempt at identifying the responsible entities — central or state governments or both in cases where convergence is not achieved.  相似文献

The aim of this paper is to analyze the economic and social cohesion in the European Union. There are different factors to explain the convergence process and besides, empirical findings are not conclusive. To the European Union, GDP per head interregional differences have decreased for certain periods but it has remained unchanged or even increased for others periods. The second report on the economic and social cohesion indicates that some decades are necessary to eliminate regional differences. These differences in regional GDP are mainly explained by differences in their productive structures, degree of innovate activity, communications structures, which depend on the relative level of transport infrastructures, and manpower qualifications. This analysis allows us to obtain some conclusions to the economic policies and the social cohesion. A preliminary version of this paper was presented in the 57th International Atlantic Conference, held in Lisbon, Portugal, March 10–14, 2004.  相似文献

We consider a model with a population consisting of earners and retired persons; elderly care is publicly provided. There is one big city, where congestion effects and agglomeration forces are at work, and a number of small villages. We show how the externalities related to population mobility lead to an inefficient spatial distribution of earners and retirees, and we characterize the second‐best solution. Decentralization of this solution in a fiscal federalism structure requires the use of taxes and subsidies proportional to the number of earners and retired persons living in the city and the villages.  相似文献

We analyze educational institutions’ incentives to set up demanding or lax curricula in duopolistic markets for education with endogenous enrolment of students. We assume that there is a positive externality from student achievement to the local economy. Comparing the case of regulated tuition fees with an unregulated market, we identify the following inefficiencies: Under regulated tuition fees schools will set up inefficiently lax curricula in an attempt to please low-quality students even if schools internalize some of the externality. On the other hand, unregulated schools set up excessively differentiated curricula in order to relax competition in tuition fees. Deregulation gets more attractive if a larger fraction of the externality is internalized.  相似文献

We propose a semiparametric hedonic model of housing prices with nonlinearity in age and cohort effects. The model avoids the simultaneity problem among age, cohort and year effects, which is a common problem in linear hedonic models. Applying the model to housing prices in Tokyo between 1990 and 2008 revealed significant nonlinearities in both the age and cohort effects, and significant interactions between these effects, with the shape of the age effect differing across housing cohorts. Estimates of the year effect indicated a declining trend in prices that was more pronounced compared with those of conventional linear hedonic models.  相似文献
