建设社会主义新农村既是我国在新时期作出的一项伟大的战略部署,又是我国在加快推进社会主义经济建设和社会和谐发展中所面临的一项艰巨的历史任务.加快社会主义新农村建设,必须选准切入点,抓住关节点,稳步推进,力求实效.     

Does computer penetration increase farmers’ income? An empirical study from China

The diffusion and adoption of modern information technology provide new chance for China to close urban-rural income gap. This paper uses China's provincial panel data from 2002 to 2013 to investigate the effect of computer penetration on rural residents' income. A public program aiming to connect every village with broadband Internet and other rural facilities provides plausibly exogenous variation in rural residents' availability and adoption of the broadband Internet, which is used to explore the instrument variable for rural computer penetration. The results show that rural computer penetration tends to increase rural residents' income over time, but the average effect remains limited. The dynamic panel threshold effects model, which allows for both the threshold variable and other covariates to be endogenous, is further used to explore the constraints of the income-increase effect of rural computer penetration. It shows that the effect is at least doubled over the average effect estimated from instrument variables method, once the digital divide causes are removed. Our findings have important implications for the government to increase rural residents' income and reduce urban-rural income gap by encouraging rural computer usage and removing the digital divide.     

我国三线城市保险业发展水平和综合竞争力的比较分析

随着保险公司在一、二线城市竞争的日趋激烈,三线城市保险业的发展商机已经显现。影响三线城市保险业发展水平和综合竞争力的主要因素包括GDP、人口数量及分布、城镇居民人均可支配收入和地理位置等,并最终反映在原保费收入、保费收入增长率、保险深度和保险密度这些衡量城市保险业竞争力和发展水平的主要客观性指标上,据此构建我国城市保险业综合竞争力评价模型,并运用此模型从实证的角度对2009年我国三线城市保险业发展水平和综合竞争力进行了测定和排序。     

辗辊式井下采油筛管的研制及应用

针对油田在用井下采油筛管防砂过程中出现的砂堵等问题,依据能量转换原理,研制出一种辗辊式井下采油筛管。辗辊式筛管既防砂又不发生砂堵,还具有穿透性和节能效果明显等特点,不仅可用于一般的采油井、含砂量大和压裂的井,还可用于污水泵的保护。     

关于GB/T20489-2006中高温、超高温聚能射孔器评价的探讨

指出了GB/T 20489-2006《油气井聚能射孔器材通用技术条件》中存在的高温、超高温聚能射孔器的耐温指标不合理、无统一评价指标等缺陷。通过对聚能射孔器井下使用条件、现场施工所需时间、国内耐高温聚能射孔器产品水平的分析,对聚能射孔器的耐温性能进行了分组并确定了评价方法和评价指标,为现场施工中射孔器的选择、标准的修订提供了依据。

ICT as a source of economic growth in the information age: Empirical evidence from the 1996-2005 period

This paper examines the hypothesis that ICT penetration has positive effects on economic growth. On theoretical grounds, this paper discusses three channels through which ICT penetration can affect growth: (i) fostering technology diffusion and innovation; (ii) enhancing the quality of decision-making by firms and households; and (iii) increasing demand and reducing production costs, which together raises the output level. This paper conducts three empirical exercises to provide a comprehensive documentation of the role of ICT as a source of growth in the 1996-2005 period. The first exercise shows that growth in 1996-2005 improved relative to the previous two decades and experienced a very significant structural change. The second exercise uses the traditional cross-country regression method to identify a strong association between ICT penetration and growth during 1996-2005, controlling for other potential growth drivers and country-fixed effects. The third exercise uses the system Generalized Method of Moment (GMM) for dynamic panel data analysis to tease out the causal link between ICT penetration and growth. This analysis also shows that, for the average country, the marginal effect of the penetration of internet users was larger than that of mobile phones, which in turn is larger than that of personal computers. The marginal effect of ICT penetration, however, lessens as the penetration increases. This paper points out several policy implications drawn from its analyses and findings.     

产业结构调整的汇率驱动路径:价格穿越模型的解释

汇率作为宏观经济调节变量,在受到其它经济条件或经济因素影响的同时,其变动对国民经济也有着广泛而复杂的作用。通过对中国汇率制度历史演进的分析,可以发现人民币汇率的变动始终与中国产业结构的调整息息相关。文章以价格这一中间变量作为动力因素,建立价格穿越模型,分析汇率变动引起产业结构调整的传导路径与作用机理。     

一种井口压装防喷装置的设计

一种井口压装防喷装置,在井口压裂过程中,用于投放油管堵塞器以堵住油管,防止井喷。其结构包括上下旋塞阀和升高短节。当钻井产生井喷时,保证旋塞阀的上下两端压力平衡,使旋塞阀可以轻松打开,升高短节内的油管堵塞器即能自动下降密封。
