The effects of population aging on industrial structure upgrading:Empirical analysis of provincial and threshold characteristics in China

Global population aging trends are intensifying,presenting multifaceted economic and social challenges for countries worldwide.As the world’s largest developing country,China has entered a phase of extreme demographic aging,posing significant questions about its impact on the ongoing upgrading of industrial structures.How does this demographic shift influence the upgrading of industrial structures,and does technological innovation mitigate or exacerbate this impact?The empirical results indicate that population aging impedes upgrading the industrial structure,while technological innovation positively affects the relationship between the two.Moreover,using technological innovation as a threshold variable,the impact of population aging on industrial structure upgrading evolves in a“gradient”manner from“impediment”to“insignificant”to“promotion”as the technological innovation levels increase.These findings offer practical guidance for tailoring industrial policies to different stages of technological advancement.

Drivers for Inter-city Innovation Networks Across Chinese Cities:Modelling Physical Versus Intangible Effects

Cross-region innovation is widely recognized as an important source of the long-term regional innovation capacity.In the recent past,a growing number of studies has investigated the network structure and mechanisms of cross-region innovation collaboration in various contexts.However,existing research mainly focuses on physical effects,such as geographical distance and high-speed railway connections.These studies ignore the intangible drivers in a changing environment,the more digitalized economy and the increasingly solidified innovation network structure.Thus,the focus of this study is on estimating determinants of innovation networks,especially on intangible drivers,which have been largely neglected so far.Using city-level data of Chinese patents(excluding Hong Kong,Macao,and Taiwan Province of China),we trace innovation networks across Chinese cities over a long period of time.By integrating a measure on Information and Communications Technology(ICT)development gap and network structural effects into the general proximity framework,this paper explores the changing mechanisms of Chinese innovation networks from a new perspective.The results show that the structure of cross-region innovation networks has changed in China.As mechanisms behind this development,the results confirm the increasingly important role of intangible drivers in Chinese inter-city innovation collaboration when controlling for effects of physical proximity,such as geographical distance.Since digitalization and coordinated development are the mainstream trends in China and other developing countries,these countries'inter-city innovation collaboration patterns will witness dramatic changes under the influence of intangible drivers.

The mechanism of realizing industrial structure upgrading through technology-driven regional innovation capacity is also discussed briefly.

Research on the Impact of Innovation Drivers on the Quality of Economic Growth in China

The quality of economic growth is a prominent issue in the process of economic growth worldwide.This paper builds relevant econometric models and uses the provincial panel data from 2003 to 2015 to analyze the impact of innovation drivers on China’s economic growth.The empirical results show that technological innovation and institutional innovation have a significant role in promoting the quality of China’s economic growth,and the effect of institutional innovation is stronger than that of technological innovation.In terms of regions,the innovation driver has the greatest contribution to the quality of economic growth in the eastern region of China,with the western and central parts ranking second and third.However,the role of institutional innovation in the eastern region is prominent,and the role of technological innovation is weak.Only institutional innovation in the central region has a significant role in promoting the quality of economic growth.Only technological innovation in the western region has a positive effect on the quality of economic growth,and the impact is weak.The regional differences in the impact of innovation-driven economic growth are obvious.

The “Island Phenomenon” in Scientific and Technological Innovation and Its Governance Approach

General Secretary Xi Jinping has repeatedly stressed that we should eliminate the "island phenomenon" in technological innovation. The "island phenomenon" negatively affects the transfer and spread of technological achievements, resulting in inefficient technological innovation and transfer, and significantly impedes the implementation of innovation-driven development strategies. The emergence of the "island phenomenon" should be attributed to a failure to give full play to the "invisible hand" of the market and the overreach or absence of government's "visible hand." Local governments can play an important role in eliminating this phenomenon by leading and guiding efforts to enhance improvements in innovation technology and transfers.

Factors influencing the internet banking adoption decision in North Cyprus: an evidence from the partial least square approach of the structural equation modeling

Purpose:This paper aims to examine how the adoption decision of the internet banking in North Cyprus would be affected based on the following dimensions;the technology features,the personal characteristics,the social environment and the expected risk.Design/methodology/approach:A self-administered survey was conducted with 291 participants responded to it.The partial least square approach of the structural equation modeling(PLS-SEM)is employed to investigate the direct effects of the proposed factors on the adoption decision.Additionally,the mediation test is used to examine indirect effects.Findings:Results showed that even though the participants appreciated the benefits of the online banking as the perceived usefulness factor exerts the greatest direct effect,they would rather use clear and easy-to-use websites,adding to that their assessments of the usefulness of these services are significantly influenced by the surrounding people’s views and prior experience.This is demonstrated by the total effects of the perceived ease of use and the subjective norm factors,which are greater than the direct effect of the perceived usefulness factor since both of these factors have significant direct and indirect effects mediated by the perceived usefulness factor.The negative impact of the perceived risk factor is weak compared to the previous factors.While the personal innovativeness factor showed the weakest effect among the proposed factors.
