Abstract
Purpose
With the help of a quasi-natural experiment on Chinese policies, this study aims to understand the actual contribution of Smart City (SC) policies to the development of information and communications technology (ICT) in different cities. It also discusses the social and digital differences that such policies may generate, with a particular focus on the potential for exacerbating urban inequalities.
Design/methodology/approach
To achieve this, the study employs a principal component analysis (PCA) to develop an ICT development indicator system. It then employs a difference-in-differences (DID) model to analyze panel data from 209 Chinese cities over the period from 2007 to 2019, examining the impact of SC policies on ICT development across various urban settings.
Findings
Our findings show that SC policies have significantly contributed to the enhancement of ICT development, especially in ICT usage. However, SC policies may inadvertently reinforce developmental disparities among cities. Compared to less developed areas, the benefits of SC policies are more pronounced in economically booming cities. This is likely due to the agglomeration of the ICT industry and the strong allure of developed urban centers for high-caliber talent.
Originality/value
This study contributes to the related literature by explaining the role of SC policies in driving ICT development and by focusing on the often-overlooked impact of SC policies on urban inequality. These findings can provide guidance to policymakers on the need to recognize and address existing urban inequalities.

Abstract
Purpose
In corridor environments, human-following robot encounter difficulties when the target turning around at the corridor intersections, as walls may cause complete occlusion. This paper aims to propose a collision-free following system for robot to track humans in corridors without a prior map.
Design/methodology/approach
In addition to following a target and avoiding collisions robustly, the proposed system calculates the positions of walls in the environment in real-time. This allows the system to maintain a stable tracking of the target even if it is obscured after turning. The proposed solution is integrated into a four-wheeled differential drive mobile robot to follow a target in a corridor environment in real-world.
Findings
The experimental results demonstrate that the robot equipped with the proposed system is capable of avoiding obstacles and following a human target robustly in the corridors. Moreover, the robot achieves a 90% success rate in maintaining a stable tracking of the target after the target turns around a corner with high speed.
Originality/value
This paper proposes a human target following system incorporating three novel features: a path planning method based on wall positions is introduced to ensure stable tracking of the target even when it is obscured due to target turns; improvements are made to the random sample consensus (RANSAC) algorithm, enhancing its accuracy in calculating wall positions. The system is integrated into a four-wheeled differential drive mobile robot effectively demonstrates its remarkable robustness and real-time performance.

Abstract
Purpose
Through examining the development of the video compact disc player industry in China, this article aims to explore the main characteristics of world‐first innovation and identify four success factors for innovation followers to launch world‐first products in catching‐up countries.
Design/methodology/approach
This article takes the form of a case study
Findings
The main characteristics of world‐first innovation in catching‐up countries include: from the demand side, innovation is mainly pulled by the local market, rather than technology‐push; from the supply side, innovation cannot isolate itself from the rest of the world – suppliers of key technologies in advanced countries play an important role; inter‐firm alliances are an increasingly important way to generate world‐first innovation; and downstream integration capabilities are required for followers to mix pieces of technologies together at competitive pricing. The success of followers from catching‐up countries to launch world‐first products hinges on the four critical factors: strengths of complementary assets; figuring out ways to meet local market demand without relying on large R&D spending; emphasizing untapped innovation opportunities by multinationals; and positioning themselves on the proper points of the globally coordinated network for innovation.
Originality/value
This article identifies the main characteristics of world‐first innovation and points out four success factors for innovation followers to launch world‐first products, which could be significant to managers in catching‐up countries. Findings of this paper are more relevant to large catching‐up countries such as India, Brazil, Mexico and Indonesia where a large domestic market could serve as important launch markets for the world‐first innovation.

Abstract
Purpose
This paper aims to present an overview of permanent magnet linear flux-switching machines (PMLFSM), field excited LFSM and hybrid excited LFSM (HELFSM) topologies as presented in literature for transportation systems such as high-speed trains and maglev systems.
Design/methodology/approach
The structural designs of different configurations are thoroughly investigated, and their respective advantages and disadvantages are examined. Based on the geometry and excitation sources, a detailed survey is carried out. Specific design and space issues, such as solid and modular structures, structure strength, excitation sources placement, utilization of PM materials, and flux leakage are investigated.
Findings
PMLFSM provide higher power density and efficiency than induction and DC machines because of the superior excitation capability of PMs. The cost of rare-earth PMs has risen sharply in the past few decades because of their frequent use, so the manufacturing cost of PMLFSM is increasing. Owing to the influence of high-energy PMs and magnetic flux concentration, the efficiency and power density are higher in such machines. PM is the only excitation source in PMLFSM and has constant remanence, limiting its applications in a wide speed operation range. Therefore, the field winding is added in the PMLFSM to flexibly regulate the magnetic field, making it a hybrid excited one. The HELFSM possess better flux linkage, high thrust force density and better flux controlling ability, leading to a wide speed range. However, the HELFSM have problems with the crowded mover, as PM, field excited and armature excitation are housed on a short mover. So, for better performance, the area of each excitation component has to compete with each other.
