对外直接投资逆向技术溢出的行业内与行业间路径检验 ——基于对空间计量方法的嫁接

创造性地对空间计量经济学中的空间相关性思想进行嫁接利用,在思路方法上进行开拓,构建反映同行业内企业间相互联系与各行业间相互关联的空间权重矩阵,建立空间杜宾模型,并以制造业为例,对ODI逆向技术溢出效应的行业内和行业间路径进行实证检验。对行业内路径的检验表明,企业全要素生产率受到同行业内其它企业ODI活动的影响,行业内企业通过ODI促进自身技术进步之后,又通过企业间各种竞争合作关系促进同行业其它企业生产率提高,行业内路径由此得以验证。对行业间路径的检验表明,各行业通过ODI促进本行业技术进步之后,又通过行业间前向与后向产业关联,对其它关联行业的技术进步和生产率提高起到促进作用,且产业完全关联下的促进作用大于直接关联,由此行业间路径得以验证。

数字化推动乡村振兴的机制、路径与对策

数字经济的多维要素是实现乡村振兴的重要抓手。文章基于我国31个省份2015—2020年的面板数据,采用动态QCA的方法对数字经济驱动乡村振兴的影响因素和组态路径进行实证研究。研究表明：数字经济的单一要素并不构成驱动乡村振兴的必要条件,但数字普惠金融的重要性逐年增加,呈明显的时间效应。组态分析发现：数字经济驱动乡村振兴存在“技术−组织规划型”和“技术−产业联动型”两条路径;时间维度上,两条路径的重要性除2017年有所下降外,其余年份总体呈上升趋势;空间维度上,东部地区主要遵循“技术−组织规划型”路径,中西部地区主要遵循“技术−产业联动型”路径,呈现明显的地区差异。最后提出持续推进乡村数字普惠金融的布局与发展,不断优化乡村数字治理体系和提升治理能力,促进数字技术要素与乡村产业的深度互融互嵌。

     

广西中期工业化纵深发展的战略思考

2011年,广西经济总量突破万亿,进入中期工业化阶段。接下来广西应该走怎样的工业化道路,是需要认真思考的问题。文章通过构建TCI指数,指出广西目前的重型化工业道路是一条不能实现经济可持续发展的道路。广西的工业发展需要走一条最优工业化道路,即按照广西的要素禀赋结构,选择最优工业技术水平,使企业具有自生能力,以最快的速度实现资本积累、技术进步和产业升级。

新型农村金融组织与县域经济协同发展研究

从当前发展现状来看,新型农村金融组织与县域经济未能互生互长,协同发展.在此情形下,建立新型农村金融组织与县域经济协同发展机制对推进两者互动发展有着重要的实践指导意义.在对新型农村金融组织与县域经济协同发展概述的基础上,分析两者协同发展要素,探讨两者协同发展的一般模式,深入研究两者协同的理想模式——门槛条件下新型金融组织深化的内生增长模型,并制定出两者协同发展路径.     

Dose safety motivation mediate the effect of psychological contract of safety on flight attendants' safety performance outcomes?: A social exchange perspective

This study proposes and tests a conceptual model that investigates the mediating effect of safety motivation linking psychological contract of safety (PCS) as manifested by employer obligations of safety and employee obligations of safety to safety violations and safety creative performance (SCP). Data were collected from a sample of flight attendants with two weeks time lag in Iran. Underpinned by social exchange theory, the results of structural equation modeling revealed that safety motivation fully mediates the simultaneous effects of PCS indicators on safety violations and SCP. Specifically, indicators of PCS jointly enhance safety motivation. In turn, safety motivation reduces safety violations, while enhancing SCP. Theoretical and practical implications evoked from the results advance existing knowledge of organizationally social interactions in promoting safety and the motivational mechanism through which PCS predicts employees' safety performance outcomes.     

Impacts of COVID-19 on aircraft usage and fuel consumption: A case study on four Chinese international airports

COVID-19 pandemic starting in early 2020 has greatly impacted human and industrial activities. Air transport in China shrank abruptly in February 2020, following a year-long gradual recovery. The airline companies reacted to this unprecedented event by dramatically reducing the flight volume and rearranging the aircraft types. As the first major economy that successfully controls the spread of COVID-19, China can provide a unique opportunity to quantify the medium-long impacts on the air transport industry. To quantify the corresponding changes and to elucidate the effects of COVID-19 in the wake of two major outbreaks centered in Wuhan and Beijing, we analyze twelve flight routes formed by four selected airports, using the Automatic Dependent Surveillance-Broadcast (ADS-B) data in 2019 and 2020. Our results show that the total flight volume in 2020 reduced to 67.8% of 2019 in China. The recovering time of flight volume was about 2–6 months, dependent on the severity. In order to unwind the severe challenge, airlines mainly relied on aircraft B738 and A321 between February and June in 2020 because the fuel consumption per seat of these two aircraft types is the lowest. Besides, fuel consumption and aircraft emissions are calculated according to the Base of Aircraft Data (BADA) and the International Civil Aviation Organization's Engine Emissions Databank (ICAO's EEDB). At the end of 2020, the ratios of daily fuel consumption and aircraft emissions of 2020 to 2019 rebounded to about 0.875, suggesting the domestic commercial flights were nearly fully recovered. Our results may provide practical guidance and meaningful expectation for commercial aircraft management for other countries.     

青海省社会信用体系建设现状与发展路径

党的十八届三中全会以来，青海省全面实施深化改革工作，地方社会信用体系建设步伐显著加快。但是，还需通过自上而下的统一部署和强有力的制度约束，来解决信用基础薄弱、共享平台缺失、建设合力不足和以点带面机制不健全等问题。提出建立“总体要求———任务分解———基础工作———专项示范———支撑体系”这样一种全面的制度安排，以此为深化青海省社会信用体系建设提供新的思路。
