我国耕地保护对策研究

保障发展和保护耕地资源这个两难命题,历史性地摆在我们面前。通过严格的规划、落实,我国耕地减少速度得到了有效遏制。但是,粮食安全问题依然存在,耕地保护形势依然严峻,耕地保护的压力依然很重,守住18亿亩耕地红线依然面临很大挑战。作者认为,我国应当通过建立耕地保护的专门法律制度,节约用地、合理规划建设用地,加强耕地生态环境治理、提高耕地质量,积极稳妥开发、复垦、整理宜农荒地,推行耕地储备制度,加大破坏耕地行为的责任追究力度等路径,来达到耕地保护的目标。

Convergence Rates to Output Growth in a Global World: The Roles of Openness and Government Size

In this article, we examine the effects of three openness measures on 54 industrial and emerging economies' output growth over the “globalization years” of 1986–2004. Controlling for standard determinants of the Solow growth model in panel data, we find positive effects of openness on real output growth. While we find support for higher convergence rates under the open economy, the convergence rates in this article for both samples are remarkably close to the 2% level documented in Mankiw et al. (1992) Mankiw, G., Romer, D. and Weil, D. 1992. A Contribution to the Empirics of Economic Growth. Quarterly Journal of Economics, 107(2): 407–437. [Crossref], [Web of Science ®] , [Google Scholar]. The inclusion of G/Y, however, reduces the speed of convergence more substantially in industrial economies.     

Money is Power: Monetary Intelligence—Love of Money and Temptation of Materialism Among Czech University Students

In this study, we develop a theoretical model of monetary intelligence (MI), explore the extent to which individuals’ meaning of money is related to the pursuit of materialistic purposes, and test our model using the whole sample and across college major and gender. We select the 15-item love of money (LOM) construct—Factors Good, Evil (Affective), Budget (Behavioral), Achievement, and Power (Cognitive)—from the Money Ethic Scale and Factors Success and Centrality and two indicators—from the Materialism Scale. Based on our data collected from 330 university students in Czech Republic, we provide the following findings. First, our formative models are superior to our reflective models. Second, for the reflective model, money represents Power, Good, Achievement, and not Evil, in the context of materialism. Our formative model suggests that those who pursuit materialism cherish Achievement (vanity) but Budget their money poorly. Third, multi-group analyses illustrate that humanities students (62.4 % female) consider money as Evil and Budget their money poorly, while those in natural sciences (37.6 % female) do not. Further, men are obsessed with Achievement, whereas women do not Budget their money properly, suggesting reflective temptation for males and impulsive temptation for females. Our novel discoveries shed new lights on the relationships between LOM and materialism and offer practical implications to the field of consumer behavior and business ethics.
