Abstract
Purpose
With the rapid development of information technologies and the internet, firms have increasingly focussed on customer interactions to realise value co-creation. Previous studies have empirically examined interaction orientation, but their measurements have been derived from goods-dominant logic and have not explained the mechanism of value co-creation. The purpose of this paper is to propose an operational definition and define the dimensions of interaction orientation based on value co-creation theory (IOVCC), and then develop a scale for it.
Design/methodology/approach
In this study, data were collected from employees via three questionnaire surveys, and then analysed using exploratory factor analysis and confirmatory factor analysis.
Findings
The findings are as follows: IOVCC represents a firm’s implementation of a set of marketing actions aimed at inserting the firm into its customers’ daily life practices and co-creating value with the customers. The construct of IOVCC consists of five behavioural dimensions: “building communication channels”, “involving customers in co-production”, “improving service capabilities”, “improving interaction quality” and “integrating interaction resources”. The measurement scale for IOVCC has acceptable levels of reliability, content validity, convergent validity, discriminant validity and nomological validity.
Originality/value
This study enriches the literature on value co-creation theory by revealing the process and actions of co-creating value. It also contributes to the understanding of service touchpoints by highlighting the interaction quality of touchpoints. In addition, the authors have developed a reliable and valid scale for IOVCC, thereby facilitating the measurement of a firm’s implementation of the “value co-creation” business philosophy.

Abstract
Purpose
The purpose of the paper was to design an anti-corrosion system that combined conductive coatings with cathodic protection for a 500-kV substation ground grid, and provide a basis for the anti-corrosion construction of the installation.
Design/methodology/approach
The study took the Shaoguan 500-kV substation grounding grid as the research object. The anti-corrosion performance of KV conductive coatings on grounding metal was researched. In parallel, the alkalinity of substation soil was evaluated according to the German DIN50929 Standard, and the combined protection system comprising conductive coatings and impressed current cathodic protection was designed.
Findings
KV conductive coatings, that have resistance to acids, alkalis and salts, can effectively slow down the corrosion rate of the grounding grid. The investigation also provided the outline design, installation, construction requirements and monitoring methods for the 500-kV substation grounding grid.
Originality/value
This report contains some guiding significance for anti-corrosion engineering of 500-kV substation grounding grids.

Abstract
Purpose
To construct a scientific and reasonable indicator system, it is necessary to design a set of standardized indicator primary selection and optimization inspection process. The purpose of this paper is to provide theoretical guidance and reference standards for the indicator system design process, laying a solid foundation for the application of the indicator system, by systematically exploring the expert evaluation method to optimize the index system to enhance its credibility and reliability, to improve its resolution and accuracy and reduce its objectivity and randomness.
Design/methodology/approach
The paper is based on system theory and statistics, and it designs the main line of “relevant theoretical analysis – identification of indicators – expert assignment and quality inspection” to achieve the design and optimization of the indicator system. First, the theoretical basis analysis, relevant factor analysis and physical process description are used to clarify the comprehensive evaluation problem and the correlation mechanism. Second, the system structure analysis, hierarchical decomposition and indicator set identification are used to complete the initial establishment of the indicator system. Third, based on expert assignment method, such as Delphi assignments, statistical analysis, t-test and non-parametric test are used to complete the expert assignment quality diagnosis of a single index, the reliability and validity test is used to perform single-index assignment correction and consistency test is used for KENDALL coordination coefficient and F-test multi-indicator expert assignment quality diagnosis.
Findings
Compared with the traditional index system construction method, the optimization process used in the study standardizes the process of index establishment, reduces subjectivity and randomness, and enhances objectivity and scientificity.
Originality/value
The innovation point and value of the paper are embodied in three aspects. First, the system design process of the combined indicator system, the multi-dimensional index screening and system optimization are carried out to ensure that the index system is scientific, reasonable and comprehensive. Second, the experts’ background is comprehensively evaluated. The objectivity and reliability of experts’ assignment are analyzed and improved on the basis of traditional methods. Third, aim at the quality of expert assignment, conduct t-test, non-parametric test of single index, and multi-optimal test of coordination and importance of multiple indicators, enhance experts the practicality of assignment and ensures the quality of expert assignment.
