从森林环境经济核算看林业对国民经济的贡献——《联合国粮农组织林业环境与经济核算指南》案例研究

以吉林省吉林市丰满区和蛟河市为案例,运用联合国粮农组织《林业环境与经济核算指南》,对林地和林木资产实物量与价值量、林产品及森林环境服务价值流量核算;估算森林为国民经济其他部门及区域提供的产品和服务价值;通过120户农户家庭抽样调查估算森林为农户家庭带来的产品价值和收入。核算结果较为客观、准确地反映了林业对国民经济和社会发展的贡献,可为制定有利于林业可持续经营的政策提供参考。

农产品流通体制演进与契约行为

市场行为、市场价格的形成都是用契约关系来联结的,契约关系的紧密程度决定了市场的发育程度。基于契约行为与交易协调机制的基本分析框架,回顾我国农产品流通体制的改革历程,考察农产品流通市场契约化的进程,即关系交易向契约交易的转变,以及契约的价格由计划定价向市场形成价格的转变两个方面。加快农产品流通市场改革,将促进我国市场经济体制改革的发展。     

粮食能源化趋势的市场效应及其应对

近年来,石油短缺、油价昂贵导致世界生物能源产业,如燃料乙醇产业迅猛扩张。而乙醇产量的迅猛增长,消耗了大量粮食类农产品(特别是玉米),从而造成全球性的"粮食能源化"问题。为应对能源危机和粮食危机的同时出现,我国应调整燃料乙醇的原料结构,采用非口粮类能源作物、庄稼废料、城市垃圾等,实现能源与粮食的双丰收,推动经济社会的可持续发展。

Analysis of space–time variability in agriculture and the environment with geostatistics

This paper gives an overview of space–time variability in agriculture and the environment. Analysis is based upon geostatistics in the framework of linear regression theory. Common procedures for spatial data are extended towards the space–time domain. Several practical studies are presented. The first study describes the use of REML to estimate semi-variogram models within the presence of trends. The second study describes the use of probability maps in an environmental statistical study. The third study describes the use of geostatistics in modelling the development of a disease in cabbage. Studies are evaluated using quadratic scoring rules.     

Is There Any Change in the Public Service Values of Different Generations of Public Administrators? The Case of Turkish Governors and District Governors

In recent public administration literature, much attention is paid to changes in public service values, including ethical values, that guide public service. This paper reports on the results of an empirical survey conducted among a group of Turkish governors and district governors (including those in service and retired) who are from different generations. By focusing on the transformation of value preferences of Turkish governors and district governors, this study tries to identify variations in values, particularly about public service ethics, in accordance with the age and the length of tenure in public service. The findings of the research show a traditional and more or less consistent value pattern for Turkish governors and district governors. The most important public service values expressed by the respondents are consistent with often-mentioned crucial public service values in the literature. New or emerging values have not been present enough among the most important public service values. In brief, the results do not lend support to the often-assumed hypothesis that traditional public service values are devaluated or degraded by the emergence of businesslike values. In other words, new emerging values could not sneak into the public service culture in any convincing manner in spite of many years of NPM rhetoric and recipes.
