Abstract
Purpose
Radical innovation involves significant technological advances that have a critical impact on both firm growth and society development. Therefore, there is a growing need to understand how to achieve radical innovation. While previous studies have examined the direct effect of digitization on firm innovation, there is still limited knowledge of how digitization affects radical innovation. This paper aims to contribute to further exploring the underlying mechanism of how digitization affects radical innovation by incorporating the serial mediation effect of absorptive capacity.
Design/methodology/approach
This paper collected data from Chinese-listed manufacturing firms from 2015 to 2021 and analyzed the data using bootstrap analysis.
Findings
The research results show that digitization has a positive impact on radical innovation. Furthermore, digitization can influence radical innovation through potential absorptive capacity and realized absorptive capacity, and the mediation effect of potential absorptive capacity and realized absorptive capacity can occur sequentially. These research results are validated by a range of robustness tests.
Originality/value
This paper contributes to the literature on digitization and radical innovation by validating a model that links digitization through absorptive capacity to radical innovation. This model helps to explain the relationship between digitization and radical innovation, which has previously been a topic of debate. This paper also contributes to the absorptive capacity literature by unpacking the asymmetric roles of the potential absorptive capacity and the realized absorptive capacity. This paper also provides valuable implications for practices.

Abstract
Purpose
This study aims to investigate the effect of microtextured tools on the geometric morphology of serrated chips, and further improve the cutting performance of polycrystalline cubic boron nitride (PCBN) tool and extend the tool life and the surface quality of the machined surface.
Design/methodology/approach
A three-dimensional finite element cutting model of hardened steel AISI D2 with microtextured PCBN tools were established using the finite element software Abaqus, and cutting tests were carried out. Furthermore, the stress distribution in the primary deformation zone was investigated based on the triaxiality of stress, and the influence of microtexture on the geometric morphology of serrated chips and crack development was researched.
Findings
The results show that compared with nontexture tools, elliptical pits and wavy grooves microtexture tools have lower serrated degree Gs, higher serrated frequency f per unit length and more miniature serrated step Pc. The serrated phenomenon is intensified because the tensile stress zone of chips generated by nontextured tools is longer than that of elliptic pits and wavy grooves microtexture tools. Simultaneously, the maximum value of triaxiality in the tensile stress zone achieved by nontexture tools is larger than that of the two microtexture tools, and chips obtained by nontextured tools are more susceptible to propagation fractures.
Originality/value
This paper mainly studies the effect of microtexture on chip microgeometry, which is relatively little studied at present. At the same time, this paper has a certain engineering significance for PCBN tool turning hardening steel.

Abstract
Purpose
The paper aims to clarify the operation rationality of high speed trains (HSTs) under tunnel condition with the speed of 400 km/h through representative aerodynamic factors including running drag, eardrum comfort, carriages noise, aerodynamic loads on tunnel ancillary facilities and HST, micro-pressure waves, and then put forward engineering suggestions for higher speed tunnel operation based on the analysis.
Design/methodology/approach
Based on the field measurement data of CR400AF-C and CR400BF-J tunnel operation, correlations between each aerodynamic indicators with HST speed were established. By analyzing the safety reserve of aerodynamic indicators at 350 km/h and the sensitivity of each indicator to HST speed increasing and the indicators’ formation mechanism, the coupling relationship between various indicators was obtained.
Findings
The sensitivity of different aerodynamic indicators to speed variation differed. The aerodynamic indicators representing flow field around HST showed a linear relationship with HST speed including noise, eardrum comfort, aerodynamic load on HST body. The positive aerodynamic load on tunnel auxiliary facilities and the micro-pressure wave at the entrance of the tunnel have the same sensitivity to the 3th-power relation of HST speed. The over-limit proportion of micro-pressure wave was the highest among the indicators, and aerodynamic buffering measures were recommended for optimization. The open tunnel pressure relief structure is recommended, while allowing trains to pass through the tunnel at an unconditional speed of 380 km/h.
Originality/value
Comprehensive evaluation of multiple aerodynamic indicators for HST tunnel operation with higher speeds was realized. The main engineering requirements to release aerodynamic effect were identified and the optimization scheme is proposed.

Abstract
Purpose
This paper examines the attitudes of young Greek University students towards genetically modified (GM) foods and studies the effect of appropriate information in shaping this attitude.
Design/methodology/approach
A questionnaire was distributed to 433 Greek students of the Technological Educational Institute of Athens during the academic year 2003‐2004. Results were processed by SPSS 11.0.
Findings
The survey reveals that although Greek University students are more informed than the general population about genetic modification issues, still a large proportion (48 per cent) are unaware of what is exactly a GM plant and 55.3 per cent believe that GM foods may impose risks for public health and the environment. However, after reading a short informative statement the “negative” attitude of respondents is decreased by 15.5 percentage units and the “positive” attitude is increased by 13.2 percentage units. These results show that appropriate information could affect the acceptability of a technological innovation. Future research is required to investigate how scientists could intervene in order to make the GM issue clear on a scientific basis.
Originality/value
The findings of this study could be useful to those who are seeking to elucidate the complex issue of GM food acceptance and have an interest in establishing communication between the scientific community and the public, such as regulatory authorities, the industry or academics.

Abstract
Purpose
This study aims to examine two innovation zones in China, including the Suzhou Industrial Park and Tianjin Eco-city, to gain a comprehensive understanding of city locations attributes and its relationship to inward foreign direct investment (FDI) from multinational enterprises (MNEs) in innovation zones embedded in nonhub cities in China.
Design/methodology/approach
This research incorporates two site visits and in-depth interviews with 39 personnel working with innovation zones. Thematic analysis is used to analyze interview data and documents.
Findings
The results highlight that cities can use innovation zones as a strategy to build high scale knowledge community precincts to connect MNEs and other global actors. As an important institutional feature of city locations, innovation zones increase within-city connectivity and connect cities in global networks resulting in cross-city connectivity to attract FDI from MNEs. From a dynamic knowledge community perspective, this research also compares active and passive approaches toward building knowledge communities and identifies several elements of knowledge communities within innovation zones in China.
Research limitations/implications
The research results could be further explored in other institutional and economic contexts, to understand the interplay of city locations, FDI and innovation zones, and the dynamics of building knowledge communities.
Practical implications
This research has several implications for policymakers and administrators who work with municipal economic development and the development and enhancement of innovation zones. It offers recommendations for MNEs to consider where to make foreign investments and the advantages innovation zones may offer to support FDI.
Originality/value
This research contributes to the literature related to economic development and how nonhub cities can attract FDI and join global networks. It offers empirical insights drawn from two successful innovation zones located in nonhub cities in China.
