Abstract
Purpose
As an important measure to promote sustainable development, green finance has developed rapidly in recent years. In order to comprehensively analyze the positive and negative indicators of the influencing factors of green finance, this paper puts forward a grey relational method of spatial-temporal panel data from the perspective of the development trend of the object dimension indicators and the performance difference between the time dimension indicators.
Design/methodology/approach
From the different perspectives of object dimension and time dimension, the positive and negative indicators are standardized differently considering the reverse of indicators and characterizing factors. The grey absolute relational degree is used to define the matrix sequence. This method reflects the development trend of objects in time and the difference characteristics among objects, which comprehensively represents the correlation between the reference panel and the comparison panel.
Findings
The results show that: (1) The object dimension reflects the internal driving force of the development of green finance in each provincial administrative region and the time dimension reflects the relationship between regional differences of influencing factors and green finance. (2) From the object dimension, the influencing factors of green finance from high to low are economic development potential, economic development level, air temperature, policy support, green innovation and air quality. (3) From the time dimension, the influencing factors of green finance from high to low are green innovation, air quality, economic development potential, economic development level, policy support and air temperature.
Originality/value
The different standardized processing methods of positive and negative indicators proposed in this paper not only eliminate the sample dimension, but also study the grey relational degree among the indicator panels from different reference dimensions. The proposed model is applied to identify the influencing factors of green finance, which expands the practical application scope of the grey relational model. The research results can provide reference for relevant departments to better promote the development of green finance.

Abstract
Purpose
Sodium alginate (Na-Alg) is a natural polysaccharide with a rich and renewable production that is widely used in the food, pharmaceutical and daily necessities industries, among other fields. The purpose of this study is to obtain a green and degradable shape memory material, calcium alginate (Ca-Alg) film was prepared and the mechanical properties, the shape memory effect of the film were investigated and confirmed.
Design/methodology/approach
The Ca-Alg films were prepared by Na-Alg, calcium chloride (CaCl2) solution, and flow extension method. Dissolve sodium alginate powder, remove bubbles, pour into petri dish, dry at 60°C, add calcium chloride solution cross-linking and finally dry naturally. The effect of CaCl2 solution concentration on the mechanical properties of the films were investigated and discussed by universal tensile tester. The shape memory behavior and degradation performance of thin films were verified and studied by the fold-deploy shape memory test and soil embedding method, respectively.
Findings
The Ca-Alg films exhibited good mechanical and shape memory properties, with a 72.2% shape memory fixity ratio and a 92.3% shape memory recovery ratio, respectively. For a period of 120 days, the film treated with a 6 wt% CaCl2 solution degraded at a rate of approximately 53%.
Research limitations/implications
Shape memory polymers (SMPs) as intelligent materials are an important research direction for the development of modern high-tech materials. On the other hand, plastic pollution is a major problem today; as a result, preparing green degradable SMPs is essential.
Originality/value
This study synthesized transparent and degradable shape memory Ca-Alg films using Na-Alg and CaCl2 solution and the flow extension method.

Abstract
Purpose
The purpose of this paper is to explore the influence mechanism of job satisfaction and positive affect on knowledge sharing among project members in Chinese construction industry, and test the moderating role of organizational commitment between them in order to find a new approach from the perspective of psychology to improve the knowledge sharing performance within project management organizations in China constantly.
Design/methodology/approach
An empirical study was used based on confirmatory factor analysis and hierarchical regression analysis with a sample of 540 project members from 80 project management organizations in China.
Findings
Research results showed that job satisfaction and positive affect of project members both have a significant positive impact on knowledge sharing; organizational commitment could moderate the influence of job satisfaction and positive affect on knowledge sharing among project members partially within the Chinese context.
Research limitations/implications
A questionnaire study from China only represents the relationship and regular pattern within a shorter time interval in the Chinese context. It is necessary to continue to implement a longitudinal study in a relatively long period in future research.
Practical implications
Knowledge sharing among project members can be enhanced through improving job satisfaction and positive affect, and strengthening project members’ organizational commitment can amplify the influence effect of job satisfaction and positive affect on knowledge sharing.
Originality/value
This paper clarifies the direct influence mechanism of project members’ job satisfaction and positive affect on explicit knowledge sharing (EKS) and tacit knowledge sharing (TKS), and further tests the partial moderating effect of organizational commitment on the influence relationship of job satisfaction and positive affect on EKS and TKS.

Abstract
Purpose
This paper aims to optimize cable-stayed force in asymmetric one-tower cable-stayed bridge formation using an improved particle swarm algorithm. It compares results with the traditional unconstrained minimum bending energy method.
Design/methodology/approach
This paper proposes an improved particle swarm algorithm to optimize cable-stayed force in bridge formation. It formulates a quadratic programming mathematical model considering the sum of bending energies of the main girder and bridge tower as the objective function. Constraints include displacements, stresses, cable-stayed force, and uniformity. The algorithm is applied to optimize the formation of an asymmetrical single-tower cable-stayed bridge, combining it with the finite element method.
Findings
The study’s findings reveal significant improvements over the minimum bending energy method. Results show that the structural displacement and internal force are within constraints, the maximum bending moment of the main girder decreases, resulting in smoother linear shape and more even internal force distribution. Additionally, the tower top offset decreases, and the bending moment change at the tower-beam junction is reduced. Moreover, diagonal cable force and cable force increase uniformly with cable length growth.
Originality/value
The improved particle swarm algorithm offers simplicity, effectiveness, and practicality in optimizing bridge-forming cable-staying force. It eliminates the need for arbitrary manual cable adjustments seen in traditional methods and effectively addresses the optimization challenge in asymmetric cable-stayed bridges.

Abstract
Purpose
A transportation connectivity strategy is a crucial part of an adaptive, congruent and sustainable tourism transportation system and is of concern to countries focusing on growing their tourism economy. This study aims to gain a better understanding of the relationship between transportation connectivity and the tourism economy through a configuration analysis.
Design/methodology/approach
This study uses fuzzy-set qualitative comparative analysis on a sample of 153 cities in China to provide an understanding of the impacts of transportation connectivity strategies, with the co-effecting factors of socio-economic status, tourism resource endowment and hospitality capacity, on the development of regional tourism economies.
Findings
There are multiple paths that lead to regional tourism economic development (a high level of tourist arrivals or a high level of tourism revenue). High-speed rail can play a supportive role, while air travel or traditional rail remains central to the tourism economy. Socio-economic status (i.e. city size and city gross domestic product) and hospitality capacity are identified as crucial influencers for the development of the tourism economy.
Research limitations/implications
This study confirms the validity of deploying configuration analysis (based on the equifinality theory) to establish the relationship between transportation and the tourism economy. The finding of more than one configuration led to a new consensus on how multiple factors influence the tourism economy.
Practical implications
Suggestions on transportation connectivity strategies for different regions are provided.
Originality/value
This study demonstrates the need to place greater emphasis on configurations that lead to tourism economy development instead of the effect of a single transportation mode.

Resumen
Propósito
Una estrategia de conectividad del transporte es una parte crucial de un sistema de transporte turístico adaptable, congruente y sostenible, y es de interés para los países que se centran en el crecimiento de su economía turística. Un análisis de la configuración puede ayudar a comprender mejor la relación entre la conectividad del transporte y la economía del turismo.
Diseño/metodología/enfoque
Este estudio utiliza el análisis comparativo cualitativo de conjuntos difusos (fsQCA) en una muestra de 153 ciudades de China para proporcionar una comprensión de los impactos de las estrategias de conectividad del transporte, con los factores coadyuvantes de la situación socioeconómica, la dotación de recursos turísticos y la capacidad de hospitalidad, en el desarrollo de las economías turísticas regionales.
Conclusiones
Existen múltiples vías que conducen al desarrollo económico del turismo regional (un alto nivel de llegadas de turistas o un alto nivel de ingresos por turismo). El ferrocarril de alta velocidad puede desempeñar un papel de apoyo, mientras que el transporte aéreo o el ferrocarril tradicional siguen siendo fundamentales para la economía turística. El estatus socioeconómico (es decir, el tamaño de la ciudad y el PIB de la ciudad) y la capacidad de hospitalidad se identifican como factores de influencia cruciales para el desarrollo de la economía del turismo.
Limitaciones/implicaciones de la investigación
Este estudio confirma la validez de utilizar el análisis de configuración (basado en la teoría de la equifinalidad) para establecer la relación entre el transporte y la economía del turismo. El hallazgo de más de una configuración condujo a un nuevo consenso sobre cómo influyen los múltiples factores en la economía del turismo.
Implicaciones practices
Se proporciona una tipología de estrategias de conectividad del transporte para diferentes regiones.
Originalidad/valor
Este estudio demuestra la necesidad de poner mayor énfasis en las configuraciones que conducen al desarrollo de la economía turística en lugar del efecto de un único modo de transporte.
