Convergence,technological interdependence and spatial externalities: a spatial dynamic panel data analysis

This study adopts a spatial dynamic panel data approach and spatial quasi-maximum likelihood to re-estimate the speed of growth convergence in 91 countries based on technological interdependence and spatial externalities. We perform a conditional Lagrange multiplier test for spatial error dependence and find some differences to previous studies. First, the switch from a cross-sectional to a dynamic panel data framework enables the estimated rate of conditional convergence to be higher, more accurate and more appropriate for realistic and theoretical expectations. Second, the spatial Durbin model (SDM) is a general form of simplified model that considers spatial error correlation, and its likelihood ratio test for the theoretical model of ‘learning by doing’ effect provides further evidence. Finally, statistical tests find that spatial correlation not only occurs in each variable, but also appears in the error term. Thus, the SDM does not exist in the assumptions associated with the spatial error, which are not necessarily correct.

基于DEA-Malmquist指数的皖江城市带利用外资研究

皖江城市带承接产业转移示范区已获国务院批准,外资的流入已成必然趋势,但对外资利用的效率与潜力成何种趋势,以及区域内部各市利用情况的差异性。文章运用DEA—Malmquist指数分析法,从宏观、微观效率和潜力三个层面对整体与各市分别客观评价,得出皖江城市带在利用外资效率方面呈增加趋势,但规模效率是影响总体效率的关键,合肥、芜湖、马鞍山和滁州在利用外资效率和潜力方面较好。     

Geographic concentration and vertical disintegration: Evidence from China

Existing theoretical literature predicts that geographic concentration encourages vertical disintegration of firms. Nevertheless, empirical evidence of this prediction is limited, especially in developing countries. Using data on manufacturing firms from China, this paper documents a positive correlation between geographic concentration and vertical disintegration. Additionally, this paper uses the instrumental variable approach to address the issue of endogeneity and finds that geographic concentration has a positive causal effect on vertical disintegration.     

一带一路战略为沿线国家创造发展新机遇

2000多年前,通过陆路和海上丝绸之路,中国把丝绸、瓷器、冶铁、耕作等商品和技术,传播到了中亚、东南亚、欧洲等地区,改善了当地的生产力和生活水平。
　　如今,中国正努力让古老丝路恢复往日的辉煌。2013年,中国提出“一带一路”（“丝绸之路经济带”和“21世纪海上丝绸之路”）战略构想,2014年丝路基金设立、亚洲基础设施投资银行签约,2015年“一带一路”建设进入务实展开阶段。     

Market power and fiscal policy in OECD countries

We compute average markups as a measure of market power throughout time and study their interaction with fiscal policy and macroeconomic variables in a VAR framework. From impulse-response functions, the results, with annual data for a set of 14 OECD countries, show that the markup (i) depicts a pro-cyclical behaviour with productivity shocks and (ii) a counter-cyclical behaviour with fiscal spending shocks. We also use a PVAR, increasing the efficiency in the estimations, which confirms the country-specific results.     

欧盟环境政策的新发展及启示

近年来,欧盟环境政策的改革和发展备受关注,在第六个环境行动计划即将结束之际,欧盟又提出了一系列环境行动指南和规划,包括生态创新行动计划、生态管理和审核计划、环境合规性援助计划、资源效率路线图、海洋战略框架、绿色公共采购等.本文对上述欧盟环境政策的最新发展进行了系统分析,并对其整体政策效果做出了评价,最后指出了欧盟环境政策对我国环境政策制定的启示和借鉴.     

城乡统筹视角下的农村劳动力资源开发研究

改革开放三十年来,农民收入有了很大提高,但城乡居民收入差距不断扩大,破解难题的核心在农民增收,农民增收的关键在于农民素质。目前我国农村劳动力资源整体素质偏低,制约农民收入的增长。加强农村教育和培训,推动农村劳动力资源开发,提高农民的整体素质,对促进农民增收,缩小城乡收入差距,统筹城乡经济协调发展有重要意义。     

超越股市的救市之争

市场机制与政府干预之间并不存在必然的矛盾,它们之间是一种相互补充、而不是相互替代的关系,其界限是市场失灵的边界,超出这一边界就是抑制.我们要辨证地看待我国政策市中的政府干预与抑制.通过分析,当前中国的股市需要救市,而在政府众多的措施中平准基金是短期最有效的.从长期来看,构建一个高效、结构合理、功能完善、运行完全的资本市场,完善资本市场基础性制度建设做起,才是保证我国资本市场长期稳定发展的根本大计.
