农机社会化服务采纳、禀赋差异与农村经济相对贫困缓解

进入以缓解相对贫困为重点的后扶贫时代，农村经济相对贫困问题仍不容忽视。农机社会化服务作为小农户与现代农业有机衔接的桥梁，对于推进乡村振兴战略和脱贫攻坚有序衔接具有重要作用。文章讨论的核心议题是农机社会化服务采纳如何缓解农村经济相对贫困，并尝试建立了“农机社会化服务采纳——禀赋差异缩小——农村经济相对贫困缓解”的理论分析框架。为此，文章首先对农机社会化服务采纳影响农村经济相对贫困的作用机制进行了理论分析，然后利用2750份河南省农户问卷调查数据，运用Logit模型，实证检验农机社会化服务采纳对农村经济相对贫困的影响，并通过替代核心自变量和变更样本的方法进行稳健性检验，运用PSM模型和IVProbit模型以及ERM模型进行内生性讨论，最后通过中介效应模型对其作用机制进行验证。结果表明，农机社会化服务采纳对农村经济相对贫困具有显著负向影响，缓解了农村经济相对贫困。考虑内生性后，结论仍具有稳健性。进一步的机制验证发现，农机社会化服务采纳通过缩小劳动力禀赋差异和技术禀赋差异，缓解农村经济相对贫困，劳动力禀赋差异缩小和技术禀赋差异缩小的中介效应占比分别为21.22%和7.36%。可见，应将完善农机社会化服务供需体系纳入农户相对贫困治理机制考虑范畴，引导农户从传统家庭化生产转向现代社会化生产，扩大农机社会化服务采纳范围；同时完善就业服务等相关配套体系以吸纳释放的弱劳动力，促进农户收入增长，缓解农村经济相对贫困。     

从《中华人民共和国物权法(草案)》谈城乡规划及其管理观念的转变

城乡规划代表公共利益,物权法保护物权人的合法权益;城乡规划及其管理代表一种调整和规范土地及地上建筑物等不动产物权的设立、行使的公共行政权力,物权法赋予了物权人对其不动产相关物权享有直接支配、排他性干涉的权力;在城乡规划及其管理工作方面,如何平衡上述两种权力?本文从城乡规划及其管理的主要环节--编制、实施、监督检查、批后管理四方面做出了阐释.     

基于成本差异的最佳贸易与产业政策选择

本文讨论了存在成本差异的第三国市场模型的最佳贸易与产业政策选择问题，讨论了社会成本和私人成本、本国和外国成本差异情况下的Cournot竞争和Bertrand竞争的情况。本文发现，在Cournot竞争下，政府首先行动时，当政府基金影子价格低于4／3时，政府对出口进行补贴，并且本国越有成本优势，补贴越高，补贴的利润转移效应越大；当政府基金影子价格高于4／3时，政府对出口征收出口税，且本国越有成本优势，征税越多。在Bertrand竞争下，当政府先行动时，对出口征收出口税；当政府后行动时，对出口进行补贴。当本国企业具有劣势时，事后补贴是最佳政蓑。     

高管层内部的级差报酬研究

本文通过对我国上市公司2004年度数据的实证研究发现, (1)随着高成长公司竞争者人数的增加、公司所处地区发达程度的提高和公司规模的扩大,公司高管层级差报酬会随之增加;随着低成长公司竞争者人数的增加和公司所处地区发达程度的提高,公司高管层级差报酬会随之增加。(2)高成长公司和低成长公司在赋予高管层级差报酬影响因素的权重上没有显著差别。(3)高成长公司的高管层级差报酬与公司市场业绩之间存在正相关关系,低成长公司的高管层级差报酬与公司每股收益指标之间存在正相关关系;竞赛理论在我国上市公司中成立。     

中国农村金融发展对城乡收入差距的影响--基于1978-2004年数据的检验

大多数研究表明,改革开放以来,中国整体金融发展显著扩大了城乡收入差距,同时,它们从城乡金融发展不平衡角度进行了理论阐释。本文则从农村自身经济发展层面出发运用1978-2004年的相关数据分析了农村金融发展与城乡收入差距之间的关系,结果显示:农村金融发展扩大了城乡收入差距,究其原因主要是农村资金的不断外流和非正规金融的不规范发展,加剧了城乡收入差距的扩大。现实的出路是遏制农村资金外流,提供更多的农村正规金融资源;规范非正规金融发展,防范农村金融风险。

国家重点科技资源支撑区域创新经济产出的空间差异研究

根据2011-2014年科技部《国家重点科技基础条件资源调查表》以及国家统计年鉴数据,首先,使用赫芬达尔指数定量描述了利用国家重点科技资源进行创新活动的非均衡性。其次,使用网络DEA方法,实证分析了2012-2014年中国(内地)各省份国家重点科技资源对区域创新发展的支撑作用。研究表明,国家重点科技资源对区域创新发展的支撑作用不仅取决于资源创新生产阶段,而且受制于重点科技资源支持下的区域创新发展阶段。重点科技资源的支撑作用还有较大提升空间,70%的省份创新成果转化能力有待提高,且大部分省份的国家重点科技资源未实现优化配置。此外,全国及东部、中部和西部国家重点科技资源对区域创新发展的支撑效率不存在绝对收敛趋势。     

Urban-rural imbalance and Tourism-Led Growth in China

This study investigates the structural effect of tourism on alleviating the urban-rural dichotomy and the moderating effect of a dual urban-rural economic structure on Tourism-Led Growth (TLG). A theoretical framework followed by an empirical analysis based on relevant data from 31 Chinese provinces for the years 1998–2013 is presented. The main conclusions of the econometric analysis are that tourism growth can help reduce the urban-rural gap in China, but that the larger the gap between urban and rural economies, the less substantial is the influence of tourism on economic growth in China. Tourism may play an important role in Central-Western and Inland China, but their relatively greater urban-rural economic gap may threaten the positive effect of tourism.     

Well-being effects of self-employment: A spatial inquiry

Our paper presents an empirical analysis of entrepreneurial well-being using a large-scale longitudinal household survey from the UK that tracks almost 50,000 individuals across seven waves over the period 2009–2017, as well as a number of exploratory case studies. We contribute to the existing literature by investigating how entrepreneurial well-being varies across locations along the urban-rural continuum, and across wealthy-deprived neighbourhoods. We use a Coarsened Exact Matching (CEM) approach to compare the well-being outcomes of individuals who switch into self-employment from waged employment, and show that entrepreneurial well-being, in the form of job satisfaction, is significantly higher for those living in semi-urban locations, relative to those living in urban and rural locations. We argue that semi-urban locations provide an optimal combination of ease of doing business and quality of life. Our results also show that individuals in wealthy neighbourhoods who switch into self-employment experience higher job satisfaction than otherwise comparable individuals living in materially deprived neighbourhoods, although the latter experience greater levels of life satisfaction following the switch.     

Microdata analysis of the consequences of free trade port policy: the case of Iran free zones

ABSTRACT

Creating free trade zones as a policy to motivate new investment and improve the local economic indicators might be of some benefits. Following of this policy in Iranian major port, however, resulted vice versa by aggravating the current account balance that is higher imports and the same horizon diminished export sums. We derive the micro data of trade for the Iranian major Imam port according to code arrangements of harmonic system (HS), which permits the clustering of different goods categories. Then we extracted the sums of survey data for the years before and after Imam port became free trade zone and applied fixed effect difference in difference (DID) method to capture the heterogeneity of unobserved variables. Our control port of analysis was Rajaee port the policy did not implemented. Results show that just as Imam free port’s Current Account Balance deteriorated by increasing import and dampening of export sums.
