多媒体技术在军事上的主要应用

科学技术在军事上的运用是推动军事变革和发展的主要因素。20世纪70年代以来兴起的信息技术革命正在引发一场新的军事革命,势不可挡地推动着世界军事的发展,特别是当今信息技术领域发展最快、最活跃的多媒体技术在军事上的广泛应用,使武器威力倍增,在一定程度上大大地提高了军队的指挥、作战和训练水平,成为军事信息革命的新热点。文章主要对其在军事情报和资料的分析与显示、C3I系统、军事模拟仿真训练等几个方面的主要作用进行了简要的分析。     

浅析计算机辅助编辑技术的应用

随着信息技术的不断发展,计算机的应用范围越来越大,在这过程中所出现的计算机辅助编辑技术,就是利用计算机来帮助传统出版进行编辑工作。在这其中利用技术来有效地收集信息,并且在网上完成对稿件的审核,在这其中包括校对、加工、目录等多方面的设计。一些出版单位应用计算机辅助编辑技术取得了较好的效果。论文首先说明计算机辅助编辑技术应用所存在的问题,然后说明提高计算机辅助编辑技术的策略。

基础设施在中国农业全要素生产率中的作用

This paper uses the Malmquist index to examine the sources of Total Factor Productivity (TFP) in Chinese agriculture. The overall goal of this study is to create a framework for assessing the trend of China’s agricultural infrastructure and to measure its impact on Total Factor Productivity. The main methodological contribution is to provide more contributive measure of crop-specific technologies. Based on the province-level panel data set during 1988–2002, the primary finding is that infrastructure has positively and statistically significant association with the estimated coefficient on Total Factor Productivity for rice, wheat, maize, and bean.

Timing and Commitment of Environmental Policy,Adoption of New Technology,and Repercussions on R&;D

We investigate the interplay between environmental policy, incentives to adoptnew technology, and repercussions on R&D. We study a model where a monopolistic upstream firm engages in R&D and sells advanced abatement technology to polluting downstream firms. We consider four different timing and commitment regimes of environmental tax and permit policies: ex post taxation (or issuing permits), interim commitment to a tax rate (a quota of permits) after observing R&D success but before adoption, and finally two types of ex antecommitment before R&D activity, one with a unique tax rate (quota of permits), the other one with a menu of tax rates (permit quotas). We study the second best tax and permit policies and rank these with respect to welfare. In particular, we find that commitment to a menu of tax rate dominates all other policy regimes.     

Adoption of improved irrigation and drainage reduction technologies under limiting environmental conditions

Modern irrigation technologies have been suggested as a means of conserving scarce water and reducing environmental pollution caused by irrigated agriculture. This paper applies an economic model of technology selection that provides a general framework to analyzing adoption of irrigation technologies under various environmental conditions. Data from the San Joaquin Valley of California is used to verify the theoretical relationships. Results suggest key variables to be considered by policy makers concerned with adoption of modern irrigation technologies. Among these variables are crop prices, water technology costs, farm organization characteristics, and the environmental conditions of the farm or the field. Policy implications were discussed and analyzed.This research was conducted while the first author was a visiting scholar with the Dept. of Agricultural Economics, University of California, Davis, and USDA-ERS, USA.     

人力资本需求与工资差距:技术、贸易和收入的影响

人力资本水平的提高和技术贸易的发展都会促进人力资本密集型技术的进步,增加高等人力资本水平劳动力的需求,从而扩大了工资差距.在商品贸易中,制成品出口比例的增加会改变我国的产品需求结构,使高等人力资本密集型产品的生产增加.同时,居民收入水平的提高带来了消费升级,也促进了高等人力资本密集型产品的生产.高等人力资本密集型产品的生产引起了高等人力资本水平劳动力需求的增加,扩大了工资差距.
