Abstract

Purpose

The purpose of this paper is to examine the efficiencies of China's foreign and domestic life insurance providers and to explore the relationship between ownership structure and the efficiencies of insurers while taking into consideration other firm attributes.

Design/methodology/approach

The data envelopment analysis (DEA) method is used to estimate the efficiencies of the insurers based on a panel data between 1999 and 2004.

Findings

The results indicate that the average efficiency scores for all the insurers are cyclical. Both technical and scale efficiency reached their peaks in 1999 and 2000 and gradually reduced for the rest of the period under examination until 2004 when average efficiency were improved again. The Tobit regression results show that the insurers' market power, the distribution channels used and the ownership structures may be attributed to the variation in the efficiencies.

Research limitations/implications

Based on the research findings and the discussion, the study provides several recommendations for policy makers, regulators and senior executives of insurers.

Practical implications

The research results highlight the importance of deregulating the sector to allow a further expansion of each individual insurer or encourage mergers and acquisitions of insurers so more efficient resource utilization can be achieved through economies of scale. It also suggests that it is imperative for insurers to recruit motivated insurance agents and offer them on‐the‐job training as a part of the management strategies for gaining technical efficiency.

Originality/value

The paper reports the development within China's insurance industry and is one of the few studies analyzing the efficiencies of China's insurers.

Abstract

Purpose

Green ambidexterity innovation and green competitive advantage are of great significance to enterprises' sustainable development. From the perspective of upper echelons theory, This paper aims to investigate the role of top managers in gaining green competitive advantage and the intermediary effect of the green ambidexterity innovation between them.

Design/methodology/approach

This paper uses empirical data from heavily polluting enterprises in China for constructing a model to infer how enterprises achieve the green competitive advantage.

Findings

The paper shows that (a) top managers' environmental awareness and the green ambidexterity innovation are both positively related to the green competitive advantage of enterprises, while there is a difference between the exploitative green innovation and the exploratory green innovation regarding the heterogeneity; the positive effect of the exploratory green innovation on enterprises' green competitive advantage is greater than that of the exploitative green innovation; (b) the green ambidexterity innovation plays a partial intermediary effect between top managers' environmental awareness and enterprises' green competitive advantage and (c) strategic flexibility positively moderates the relation between the green ambidexterity innovation and the green competitive advantage. The study concludes that top managers' environmental awareness has a significantly positive impact on reinforcing green competitive advantages and adopting the green ambidexterity innovation for heavily polluting enterprises in China.

Originality/value

This paper contributes to the green innovation management literature by offering a theoretical framework for examining how top managers' environmental awareness influences enterprises' green competitive advantage.

Abstract

Purpose

The purpose of this study is to explore the green innovation evolution in coal enterprises in China and the various driving mechanisms influenced by government regulations, enterprise resource capability and supply chain integration.

Design/methodology/approach

This paper uses the innovation data of coal enterprises in China for constructing a model to infer how enterprises achieve green innovation (the “hybrid drive effect model”).

Findings

This paper shows that various driving modes of green innovation in an enterprise are influenced by government regulations, enterprise resource and capability, supply chain integration and the interaction effects between any two actors.

Originality/value

By examining the evolution process of green innovation in a specific industry from the perspectives of exploitative and exploratory innovation, the paper touches a relatively novel view on green innovation.

Abstract

Purpose

Self-organization has been regarded as a tool for the synthesis of well-defined organic nanostructures. Heterocyclic annulated perylene diimides are the subjects of considerable current research studies. The purpose of this study is to reveal the photophysical property, electronic structure and solid-state packing of O-heterocyclic annulated perylene diimide.

Design/methodology/approach

Asymmetrically five-membered O-heterocyclic annulated perylene diimide (OAPDI) was synthesized. Structure and purity of OAPDI were confirmed by 1H NMR, 13C NMR, IR and mass spectral techniques. Photophysical properties of OAPDI were studied using UV–vis absorption and fluorescence in both solution (CHCl3) and solid state. Scanning electron microscopic and atomic force microscopy were used to characterize the surface morphology of OAPDI. Conducting properties of the OAPDI were evaluated by current–voltage measurements. The compounds geometries were also optimized at 6-31G* using density functional theory.

Findings

The UV–vis absorption and fluorescence spectra of OAPDI in solution are blue-shifted in comparison with that of unsubstituted perylene bisimide. Solid-state UV–vis measurements of OAPDI indicate that it is capable of forming highly ordered structure. The non-covalent interactions, electrostatic attraction and p-p stacking moieties of OAPDI synergistically guide assembly and domain growth while maintaining the interpenetrating network of nanofibers in the solid film. The OAPDI gave higher current at −2.0 V (0.68 µA) and 4.0 V (1.0 µA).

Originality/value

This study will be helpful for exploring feasible routes to acquire soluble perylene diimides and well-defined organic nanostructures. Furthermore, such molecular tailoring approach would be helpful for designing and synthesizing novel organic semiconductive materials with excellent charge-transporting and light-emitting capabilities.
