Board gender diversity is an important component of sound corporate governance. This paper aims to examine the influence that female board directors in listed firms in Korea have on effective investment decisions.

The authors used 4,117 data items related to finance and governance from FnGuide for listed Korean firms between 2014 and 2019. The authors analyzed the data using Heckman’s two-stage regression, controlling the ordinary least square regression and endogeneity, to resolve the problem of selection bias. Gender diversity was measured using the existence/absence of female directors on boards (dummy variable) and the ratio of female directors on boards (BLAUt-1 index and SHANNONt-1 index).

Female board directors influenced the suppression of under-investment for the enhancement of corporate value, but not the suppression of over-investment. Additionally, female directors played a complementary role in under-investment to mitigate corporate risk, but not in intra-industry competition. Kanter’s classification of board types indicated that the skewed board and tilted board have a significant effect on under-investment and play a complementary role in corporate risk.

First, this study is about only Korean firms. Second, this study relies on corporate actual data but does not account for the factors that affect human behavior or how such behaviors can evolve. Third, the authors included as many appropriate variables as possible when setting the research model, but there may be missing correlation variables.

The authors’ results have policy implications, as they can be used as a basis to establish policies related to gender diversity in Korea, where there are currently insufficient empirical studies on women’s participation on the boards of directors. Moreover, with the amended FISCMA, which mandates that firms must hire at least one female director, Korean firms need to implement practical employment policies that can benefit firms, by selecting capable female directors rather than engaging in tokenism.

This study empirically examines gender diversity in the boards of Korean firms that have implemented the female quota system for the first time and considers female board directors’ roles in undertaking effective corporate investment decisions. This insight can guide change management and help firms avoid tokenism – a possible corporate response to pressures arising from the debates about feminism in Korea and gender diversity legislation.

Chinese consumers’ cross-border internet shopping, so called “haitao” is an emerging popular trend in China. Haitao can be understood as service innovation process because it creates new market spaces and provides differentiated values for Chinese customers.

This study aims to explore the service innovation strategies and success factors of haitao business in the Chinese market. The authors selected two successful haitao sites of Amazon.cn and Gmarket.co.kr, as representatives of a global player and a niche player, and conducted a comparative case study to analyze their service innovation strategies and key success factors.

This comparative case analysis based on value chain framework revealed some common success factors such as trust, advanced system and alliances as well as their service innovation efforts. Amazon has advantages such as efficient logistics system and global sourcing, whereas Gmarket has advantages such as product category, sales promotions, and payment system.

This study provides some implications for managers with localization, alliances and platform strategies.

This paper deconstructs the boundary-spanning technology innovation (BSTI) of manufacturing enterprises based on dual-meta and dual-degree perspective. We aim to explore the impact of differentiated internal reconfigurations on networking capabilities and, thus, different BSTIs and then reveal the optimal transformation paths of different BSTIs.

We use fuzzy-set qualitative comparative analysis (fsQCA) to conduct an empirical study on 128 manufacturing enterprises in China to reveal the heterogeneous combinatorial path of internal reconfigurations on BSTI through the networking capability, and the case analysis in specific technology fields of Haier, Gree, Midea and TBEA is used to verify our results. The transfer entropy (TE) method is used to reveal the best transformation paths of different BSTIs.

The results show that the manufacturing enterprises follow the “I,” “T,” “⊥” and “|” reconfiguration logic to effectively realize multiple boundaries breakthrough (MBB), tick boundaries breakthrough (TBB), multiple boundaries reproducing (MBR) and tick boundaries reproducing (TBR) BSTI, respectively. The BSTI has two adjacent transformations named “dual-meta transformations” and “dual-degree transformations.” Nonadjacent transformations follow the “clockwise” transformation law. In “quality transformation,” “degree” transforms first and then “meta” follows, while in “feature transformation,” “meta” transforms first and then degree follows.

Firstly, the scientific classification of BSTI is carried out to guide enterprises to carry out accurate BSTI. Secondly, the “internal reconfiguration-networking capability-BSTI” paths of manufacturing enterprises are explored. Finally, the different laws of different BSTIs’ transformations are revealed.

The main purpose of this paper is to propose a quasi-impedance source (QIS) converter fed switched reluctance motor (SRM) drive. The proposed converter topology is configured for DC link capacitance minimization and power factor (PF) correction.

A QIS converter is used as a front end converter to reduce the bulk capacitance requirement during current commutation and to decline the power ripple. To improve the PF with reduced total harmonic distortion at the input current, the PF current control loop is merged with the QIS converter control loop.

The overall SRM drive speed is regulated over a wide range by controlling the DC link voltage. The voltage regulation can be achieved by pulse width modulation of the QIS converter. Hence, the overall system efficiency has been improved by operating the proposed converter at a low switching frequency. Moreover, the proposed QIS converter uses an advanced repetitive controller to achieve voltage regulation and fewer ripples in torque.

The steady state and dynamic analyzes have been performed on the proposed drive topology. The performance of the proposed topology has been simulated through MATLAB/Simulink environment. A hardware prototype with a processor of Xilinx SPARTAN 6 field-programmable gate array has been used to validate the experimental response with the simulation results.
