外商在华直接投资（FDI）对中国经济发展的积极作用之一是促进中国劳动力技能升级。本文揭示了FDI通过各种途径促进劳动力技能升级的作用机制。FDI流向有很强的区域集中性，同时也揭示了FDI区域集中对劳动力技能升级的影响。     

灰色关联度法在特种设备事故统计分析中的应用

本文以提升安全监察部门和监督检验部门综合分析能力为目的,应用灰色关联度分析方法对历年来特种设备事故的统计资料进行综合分析,以承压类特种设备为例,把特种设备总量、不同种类特种设备总量和不同种类特种设备分别造成的经济损失为指标,分析其与事故造成的直接经济损失总量之间的关联性。增强了对于统计数据综合分析的灵活性,克服了不同量纲数据之间无法寻找规律的不足,从不同角度找到指标之间的关联性,为安全监察部门和监督检验部门分析问题开拓了思路,便于其发现关键指标的主要影响因素,提前预防和集中控制力量。     

民航灾害的复杂性特征探索

民航灾害作为一种高度复杂的社会现象,它具有非线性、多样性、突发性、随机性、整体性、多变性、统计性和屯规律性等复杂性特征.提出将民航灾害看作一个复杂系统,借助分形理论、混沌理论、人工神经网络等复杂性科学的工具,并结合预警管理方法,对民航灾害的复杂性进行探索,初步构造了民航灾害复杂性研究的理论框架.     

商业银行加强市场营销的策略选择

推行市场营销,是现代商业银行面临的经营选择,也是金融竞争的大势所趋.从整体来看,目前我国商业银行的市场营销水平还处于较低层次,因此,必须牢固树立营销观念,发现和把握市场机会,进行市场细分,确定目标市场,实施一体化的市场营销战略,采取适宜的价格策略,提高营销质量.     

我国国债规模的现状及趋势研究

近年来,我国政府采取了积极的国债政策,扩大国债发行规模,筹集资金用以加大公共投资支出.这对推动经济的发展起到了至关重要的作用.但是由于国债余额增长速度过快,偿债率和国债依存度指标已处于高位,所以应适度控制国债发行规模,降低财政的债务风险.

The contribution of social tourism to sustainable tourism: a case study of seasonally adjusted programmes in Spain

Recent policy from the European Union has attempted to justify social tourism initiatives on the basis that they lead to a more sustainable tourism industry. However, the majority of latest research in the field has been focused on the benefits for participants, with the addition of some evidence on the economic impacts of such programmes on destinations, which have pointed towards sustainability outcomes including: a longer tourism season, more even spread of demand, and longer periods of employment for tourism workers. Yet there is a lack of direct evidence linking such programme to these outcomes. This paper aimed to explore this important disconnect between policy assumptions and evidence-based outcomes through an analysis of the deseasonalising effects of the Spanish social tourism programme for older people. The research found that this programme does have an effect on the seasonal nature of employment and economic activity in most regions studied, but that the huge volume of demand from international tourists in the high seasons masks the quantitative effects in the regions with the highest seasonal concentration of international tourists. Recommendations for policy and practice in sustainable tourism are made that are transferable to many countries and regions that adopt social tourism programmes.     

新兴产业对经济发展的时变性影响——来自京津冀地区的经验分析

本文建立了带有随机波动率的时变参数向量自回归模型（SV-TVP-VAR）,以京津冀地区为研究对象,分析了不同时期新兴产业发展对地区生产总值、财政收入以及就业的影响。研究结果发现：（1）新常态时期新兴产业的发展对京津冀经济状况的影响程度大于在全球经济危机时期和经济高速发展时期的影响程度,但在大部分时期新兴产业的发展都只会对京津冀的经济状况产生负向效应;（2）如果经济增长是首要经济目标,天津应该加强新兴产业的发展,如果就业是首要经济目标,河北应该加强新兴产业的发展。     

Is there a slowdown in agricultural productivity growth in South America?

This article estimates agricultural productivity growth in 10 South American countries in 1969–2009 with the objective of investigating if the slowdown being measured in other countries is present in the region. Results show that productivity growth accounts for half of the three‐fold increase in agricultural output during this period and that performance is sensitive to R&D investments in the sector. The slowdown found for the 1990s to 2000s in the U.S. and some European economies does not seem to be present yet in South America. The region's total factor productivity (TFP) growth rate increased steadily from 1.07% during the 1970s to 2.29% during the 2000s. Given lags in adoption and the adaptive nature of innovations in these economies, we have yet to see the potential effects in South American agriculture of decreases in R&D in advanced economies.     

Spatial determinants of productivity growth on agri‐food Spanish firms: a comparison between cooperatives and investor‐owned firms

This study analyses the effect of the spatial factor, location, and interaction effects among peer companies, on the productivity growth of agri‐food companies in Spain. With this aim, we build a productivity growth index and apply a multiequational Seemingly Unrelated Regression on a sample of 344 Spanish cooperatives and investor‐owned firms for the period 2010–2012. Our findings show that agri‐food firms are influenced by spatial factors finding interesting differences between cooperatives and investor‐owned firms. With regard to the geographical location, cooperatives in the western of Spain show higher productivity growth rates, whereas investor‐owned firms in the northeast of Spain present better results. The interaction effect among closer peer companies is also a relevant factor to determine the productivity growth in agri‐food companies. This factor is more relevant for cooperatives than for investor‐owned firms.
