城市化是我国经济社会发展的长期战略,新农村建设是党和国家促进经济社会稳定和谐发展的具有战略性意义的基本国策,如何准确定位新农村建设政策目标,客观评价新农村建设绩效已成为破解基层新农村建设实践中困惑与盲目的有效突破口。然而,目前新农村建设目标定位和建设绩效评价中存在的误区引发了新农村建设与城市化进程契合综合评价中软件指标的缺失。故应在明晰新农村建设与城市化进程契合内涵的基础上,从主观型和客观型契合角度探讨新农村建设与城市化进程契合软件指标体系的构建,在城乡文化的矛盾碰撞与熔合中构建新型城市文明。 相似文献

The paper examines the impact of the Science and Technology Basic Law (STBL) enactment of 1999 on the transformation of public sector research (PSR) in Taiwan. The paper proposes a research framework to assess the changes on PSR mainly through four dimensions: (1) new infrastructure build-up, (2) industrial research links, (3) patenting and licensing, and (4) industrial education/training. Nine research hypotheses are developed. Based on the survey data of 107 PSR establishments, the paper reveals that Taiwan PSR has experienced a burgeoning infrastructure build-up and a more active partnership with industry in the post-STBL period. However, the paper argues that the scientific-economic transformation of PSR in Taiwan tends to develop better “industrial collaborative research and training capabilities” than “patenting and licensing capabilities” in the preliminary post-STBL period. The divergence on patenting, licensing and partnership capabilities still persists between experienced PSREs and non-experienced ones, suggesting a learning effect. These findings provide crucial policy implications to delineate appropriate roles of PSR in the new scientific-economic regime. 相似文献

This paper sets up a two-good (domestically- and internationally-produced goods) model of a small open economy with consumption externalities and uses it to examine the optimal taxation. Since keeping up with the Joneses leads an individual consumption's to impose a negative externality on the consumption of others, a consumption tax and tariff are thereby socially desirable to correct this distortion. Due to the fact that the government has to account for additional distortion caused by consumer ethnocentrism and that keeping up with the Joneses in the consumption of domestic goods tends to reinforce the influence of ethnocentrism on the purchase of domestic products, the consumption of imported goods is subject to a higher tariff rate because of the cross-market externality. Of interest, if consumption only involves an own-market externality, there is no cyclical consequence for the optimal taxes. However, if consumption involves both own- and cross-market externalities, the optimal tariff is state-contingent and, more specifically, is countercyclical. 相似文献

Military expenditure and economic growth across different groups: A dynamic panel Granger-causality approach 总被引:1,自引:0,他引:1
Applying GMM (Arellano and Bond, 1991) to panel data of 90 countries spanning over 1992–2006, this paper explores possible relationships between military expenditure and economic growth. Based on the definitions of income levels by the World Bank – high, middle and low – our results indicate military spending leads negatively economic growth for the panels of low income countries with a marginally significance level of 10%. Of four different regional panels (Africa, Europe, the Middle East–South Asia and Pacific Rim), a negative but stronger (5% significance level) causal relationship from military expenditure to economic growth is found for the Europe and Middle East–South Asia regions. 相似文献
