Overqualification is a growing concern for employers in many countries. The practice of mismatching employees and positions inevitably leads to an increase in organizational training and management costs. This study can not only further enrich the theoretical achievements in the field of human resource management, but can also provide a reference for enterprise managers on how to effectively stimulate employees' innovative behaviour.

503 questionnaire responses were analysed using SPSS 24.0 and Mplus 8.0.

It was concluded that, (1) perceived overqualification is negatively related to employees' innovation behaviour (β = −0.32, p < 0.001); (2) psychological contract breach and psychological distance partially mediate the relationship between perceived overqualification and employees' innovation behaviour. Among them, the mediating effect of psychological contract breach was −0.14 (p < 0.01), and that of psychological distance was −0.12 (p < 0.001); the chain-mediating effect of psychological contract breach and psychological distance was −0.09 (p < 0.01); (3) employment relationship atmosphere played a moderating role in the relationship between perceived overqualification and employees' innovation behaviour (β = 0.04, p < 0.01).

This study verifies the negative impact of perceived overqualification on employee innovation behaviour and reveals the mediating role of psychological factors between the two. It also discusses the moderating effect of employment relationship climate on the relationship between perceived overqualification and employees' innovation behaviour.

The purpose of this paper is to present an automated method for complicated truss structure subassembly identification.

A community-detecting algorithm is introduced and adapted to reach the target. The ratio between oriented bounding boxes of parts is used as the weight to reflect the compact degree of assembly relationships. The authors also propose a method to merge nodes together at cut-vertex in model, by which the solving process could be accelerated.

This method could identify the subassemblies of complex truss structures according to the specific requirements.

This research area is limited to truss structures. This research offers a new method in assembly sequences planning area. It could identify subassemblies in complex truss structures, with which the existing method is not adequate to deal.

This method could facilitate the complex truss structures assembly planning, lower the human errors and reduce the planning time.

The method could inspire general assembly analysis planning.

Industrial land renewal is a significant constituent of urban environment and sustainable development. Most implementation in planning of renewal of industrial land has been mainly conducted at the site level of industrial zones or parks and the larger scale of township planning deserve further attention in China. To fill this gap, this paper aims to investigate the implementation of industrial land renewal for a whole urbanized area under the township master planning.

This study introduces a progressive approach to identify and evaluate the renewal of industrial land in township master planning to move toward a more practical understanding of industrial transition. The authors chose a typical industrialized town, Lijia in Changzhou City, under the development model of “Southern Jiangsu” to explain the measurement and assessment framework to identify and evaluate the renewable industrial land. Synthesizing the idea of sustainable development, the authors investigated the renewable industrial land with an econometric model including multiple-indexes of economic, social and ecological aspects, field observations and depth interviews.

The analysis demonstrated the spatial heterogeneity and complex generous structure of industrial land renewal in developing countries. It pointed out the major responsibility of enterprises as main industrial land users and indispensable responsibility of government and society. Following the idea of organic concentration and avoiding one-size-fits-all kind of deal, the master planning of Lijia emphasized the connection of industrial land and the combination of market force, social force and government regulation.

With original data and discussion, the authors provide more scientific renewal strategies for planners in sustainable development.
