A spatial autoregressive stochastic frontier model for panel data incorporating a model of technical inefficiency

By integrating Battese and Coelli’s (1995) model and the spatial autoregressive model (SAR), a spatial autoregressive stochastic frontier model for panel data is developed. The main feature of this frontier model is a spatial lag term of explained variables and the joint structure of a production possibility frontier with a model of technical inefficiency. The model addresses both spatial dependence and heteroskedastic technical inefficiency. This study applies maximum likelihood methods considering the endogenous spatial lag term. The proposed model nests several existing models. Further, an empirical analysis using data on the Japanese manufacturing industry is conducted and the existing models are tested against the proposed model, which is found to be statistically supported. The findings suggest that estimates in the existing spatial and non-spatial models may exhibit bias because of lack of determinants of technical inefficiency, as well as a spatial lag. This bias also affects the technical efficiency score and its ranking.     

Determinants of the allocative,cost and scope efficiencies of Indian banks

ABSTRACT

This study aims to investigate the impact of competition on determinants of allocative, scope and cost efficiencies of Indian scheduled commercial banks (SCBs). Specifically, the study, analyzes the impact of the second round of licensing on the efficiency of Indian SCBs. This is the first paper to measure scope efficiency of Indian banks and analyze its determinants. A two-stage analysis is performed on a balanced panel dataset of Indian SCBs for the period 1999–2016. In the first stage, the allocative, cost and scope efficiencies for each bank are estimated following the data envelopment analysis approach. In the second stage, internal determinants of the stated efficiency measures are estimated following the system of the generalized method of moments approach. The findings suggest that competition has not resulted in enhancing the efficiency of Indian SCBs. Among factors that can influence efficiency, it is seen that size does matter. Larger banks can enhance the efficiency of SCBs. It is also seen that having more foreign banks improves the overall efficiency of SCBs. However, before embarking on further rounds of licensing, the study posits that market-driven correction to succeed, it is imperative to address sunspots in the form of investor or borrower repression.     

Chinese banking reforms in perspective: towards global alignment or national specificity?

The reforms of the banking sector in China conducted so far have been seeking to accomplish, simultaneously, two conflicting goals. On the one hand, the objective was to prepare Chinese banks for international competition and put them at the pace with the transformations observed in its overall economy. On the other, there is a social-driven agenda concerning employment and regional inequalities. Using principal component analysis, this article explores the impact of the ongoing reforms in the Chinese banking sector on the performance of individual banks. The results show that despite identical regulation, business practices can be dissimilar at the individual level. Taken collectively, the results also show the increasing influence of Western management standards in the Chinese banking sector.     

高端乡村旅游产业与生态环保基础设施协同发展研究——以天津蓟州区为例

在经济新常态下积极推动发展高端乡村旅游产业已经成为我国建设美丽乡村的重要着力点,与此同时"反生态"问题的不断显现已成为阻碍我国乡村旅游经济实现可持续发展的掣肘,因此,高端乡村旅游产业的发展模式向生态化转型势在必行。以天津市蓟州区乡村旅游景区的环保基础设施为研究对象,从环境情况、设施配备和从业人员3个方面确定了20个影响因素,通过向游客发放问卷进行满意度调查,从游客感知角度的基础上采用IPA模型分析游客对景区环保基础设施的重要性和满意度。结果表明,准则层及指标层感知均值都为游后感知实绩(满意度)<游前期望(重要性),在此基础上提出用冲突协同理论来指导蓟州区高端乡村旅游产业发展中的环境管理工作,实现高端乡村旅游产业与环保基础设施的协同发展,也能为今后的相关研究奠定基础。     

海南省旅游业发展对经济增长的拉动效应研究

[目的]海南当前处于国际旅游岛建设和全面建成小康社会的关键时期,旅游业作为海南省的主导产业对海南经济发展的支撑作用显著增强,在此形势下,分析旅游业发展对海南经济增长的拉动效应,有利于为进一步提升旅游业对海南区域经济发展的影响,促进区域经济发展和经济结构转型,提出科学可行的对策和建议。[方法]文章从时间和空间两个维度,运用旅游业依存度、贡献率和拉动率3个指标,以旅游收入与地区生产总值等统计指标为基础,探讨了海南省旅游业对经济增长的拉动效应。[结果]从时间维度来看,海南省旅游业对地区经济增长的拉动作用进一步加大;从空间维度来看,海南省旅游业的拉动效应并不突出;从市(县)域维度来看,海南省各市(县)旅游业对经济增长拉动效应存在空间差异,东部地区拉动效应持续增长,中部地区增长势头迅猛,北部地区增长缓慢。[结论]不断完善海南旅游基础设施与管理体系;要不断细分和规范旅游产品,提升旅游产品的吸引力和复购率,完善营销及咨询服务体系;注意与其他产业的协调发展,加强与周边省份的交流与合作,省内要因地制宜,挖掘各地旅游业发展特色,推动各市(县)均衡发展,以进一步加强海南省旅游支柱产业的作用,并快速实现区域经济跨越式发展。     

FDI与我国高技术产业技术创新关系研究——基于2005-2014年省际面板数据

改革开放以来，中国大量吸引外商直接投资，期望以此提升国内的技术创新能力。然而，在当前的背景下，我国期望通过FDI提高技术创新能力的目标是否已经实现？我国各地区高新技术产业究竟需不需要外资？等问题值得我们深入研究。实证结果表明：FDI对我国东部地区高技术产业的影响为正，对其他地区影响为负。因此，应当根据我国各地区高技术产业发展水平，实施差异化引资策略，加强知识积累、人力资本建设，为高技术产业的发展提供基础。     

河北省产业承接的技术溢出效应研究

京津冀协同发展战略上升为国家战略,河北加快承接京津产业转移的步伐,对河北经济转型升级和科技创新能力提升具有重要意义。以河北省为研究对象,基于2005-2016年的数据,使用DEA的曼奎斯特指数方法测算出河北省十二年的技术进步变化情况,并以此为核心变量建立技术溢出模型实证检验了产业承接的技术溢出效应。研究结果发现,河北存在承接区际产业的技术溢出效应,但FDI的技术溢出效应并不显著;R&D经费投入对河北技术进步的促进作用最为明显,而人力资本投入对技术进步的拉升作用较小。     

基于农业发展方式转变的江苏省农业产业升级发展研究

[目的]从定量方面对江苏省农业发展方式转变对农业产业升级贡献结果进行研究,以准确把握江苏省农业发展方式转变进程。[方法]构建基于农业发展方式转变的江苏省农业产业升级评价指标体系,以2007—2016年江苏省10年的年度数据为研究对象,采用熵值法计算各年度每个指标权重以及各准则层和农业发展方式转变综合得分值。[结果](1) 2007—2016年江苏省农业产业方式转变取得了一定成效,处于良好的发展势头;(2) 2012和2014年江苏省基于农业发展方式转变的农业产业升级增长最快,2016年出现大幅下跌,导致该下跌的原因是同时期农业集约型效益的大幅下降;(3)集约型升级和高效型升级对基于农业发展方式转变的江苏省农业产业升级带动作用最大;结构合理型升级发展滞后。[结论]江苏省基于农业发展方式转变的农业产业升级还处于不断探索阶段,加速农业产业结构升级对于江苏省加快转变农业发展方式尤为重要。     

Financial development,economic growth and convergence clubs

To study the role of financial development in economic growth, we apply an array of convergence tests designed to capture nonlinear transitional dynamics to real outputs per capita. Strong evidence of multiple convergence clubs is observed, implying that the clubs are formed based on the initial level of real output per capita and average growth rate. Our empirical results show that the stage of economic growth of each country plays an important role for the composition of the convergence clubs. Furthermore, financial development emerges to be a significant determinant, albeit plays differently in the economic growth of each convergence club.
