Using the practice of foreign agricultural logistics for reference

China is a big agricultural country, but because of region, technology, policy and other reasons, Chinese agricultural products have not got a good circulation in nationwide scope. With the diversion of bottleneck which affects peasants＇ income from production field to circulation field, developing agricultural logistics has been a breakthrough to solve rural problems. The paper proposes some references, which are useful to solve ＂three agricultural problems＂, increase peasants＇ income and develop rural economy.     

Food price increases and net food importing countries: lessons from the recent past

Recent increases in food and other commodity prices have highlighted concerns that many poor countries are net food importers and higher food prices would worsen their trade balances. In this article, we analyze the changes in food trade balances associated with the 32% increase in food prices from 2000/2001 to 2004/2005. We find a small deterioration in food trade balances of low‐income countries and an improvement in middle‐income countries. The deterioration is most severe for countries in conflict and small island states, so attention should be placed first on these countries and on a few very‐low‐income countries that are also vulnerable. Because low‐income countries as a group had much lower agricultural GDP growth rates than middle‐income countries, the answers to food vulnerability in low‐income countries should probably be addressed within the context of incentives for agricultural production.     

发达国家林产品绿色政府采购政策兴起及发展趋势

回顾了英国、新西兰、丹麦、法国、日本等发达国家的林产品绿色政府采购政策兴起及其历程,并对未来发展趋势进行分析。虽然实施时间比较短,林产品绿色政府采购政策的实施效果尚难以得到准确评估,但从长远来看,实施林产品绿色政府采购政策将促进林产品的合法交易和相关国家木材的可持续发展,具有较好的发展前景。另一方面因国情不同,木材贸易现状各异,目前各国对林产品绿色政府采购政策分歧较大。中国作为木材贸易大国,对此应加以重视。     

Impact of agricultural innovation adoption: a meta‐analysis

The impacts of adopting agricultural innovation and technology are widely examined. This paper synthesises 154 studies, which yielded a total of 600 estimates of the impact of adopting agricultural innovation and technology on production, social and economic outcomes. Using meta‐regression analysis, the empirical results show that the reported impact of adopting agricultural innovation and technology rises significantly over time, notwithstanding a significant publication bias. Whether studies find significant impacts of adopting agricultural innovation and technology depends on the use of experimental research designs, parametric method, endogenous switching regression and region. Our results show a large bias in the literature towards agricultural innovations and technologies that focus on high‐yielding varieties and thus, neglect other forms of complementary innovations and technologies.     

中国与葡语国家商品贸易的竞争与互补性研究

本文基于2003~2015年中国与葡语国家商品贸易的SITC分类资料,分别采用RCA、ESI和TCI指数研究双方商品贸易的竞争性与互补性。研究发现,中国与葡语国家的出口相似度总体较低,不存在强的竞争性。中国在资源密集型产品贸易中不具有比较优势,葡语国家出口中国该类产品的互补性较强;中国在劳动密集型、资本和技术密集型产品贸易中具有较强的比较优势,葡语国家进口中国该类型产品的互补性很强。     

基于OECD 国家面板数据的金融风险影响 因素研究

本文选取1980~2013年OECD 28个国家经济与金融的样本数据,采用面板logit模型对这些国家金融风险的影响因素进行逐步回归分析。结果显示,GDP增长率、经常账户余额占GDP比率以及总储备占GDP的比率对OECD国家金融风险的影响是负向的,即随着它们的增长,金融风险产生的概率减小;汇率对OECD国家金融风险的影响是正向的,即随着汇率的增长,金融风险产生的概率增大。     

Exporting status and success in innovation: evidence from CIS micro data for EU countries

Using a large sample of micro data from four waves of Community Innovation Survey for EU member states, we investigate the relationship between firms’ export status and different sorts of innovation activities. We find systematically positive relationship between the two, whereby the strongest correlation is found in case of product innovation and the weakest in case of organizational innovations. While aggregate data show that innovation success is increasing in firm size, we find that exporting has the strongest effect on innovation in the medium-sized firms. We also explore cross-country differences in the impact of export status on innovation. Countries with a higher share of exports in GDP and greater share of spending on research and development generally display a stronger correlation between exporting status and innovation.     

保险发展与经济增长——OECD与基础四国的对比分析

本文检验了OECD国家与基础四国保险业发展对经济增长的作用是否存在差异。实证结果表明,OECD国家保险业的发展显著地促进了经济增长,保险业与银行业之间形成了良好的互补关系;基础四国的非寿险业推动了经济增长,但是寿险业的经济增长效应显著为负,保险业与银行业和股票市场之间均呈现出显著的替代关系。
