# Coordination mechanism of construction industry supply chain based on data elements

## TL;DR

This paper introduces a new way to improve construction industry coordination using data and contracts, leading to better collaboration and profits.

## Contribution

The novel integration of data elements with cost-sharing and profit-sharing contracts in construction supply chain coordination.

## Key findings

- Inefficiencies in supply chain coordination are identified in non-contractual environments.
- Cost-sharing and profit-sharing contracts significantly improve coordination and profitability.
- Practical case studies and simulations verify the effectiveness of the proposed model.

## Abstract

This paper presents a comprehensive approach to enhancing the coordination of the construction industry supply chain by incorporating data elements into the decision-making process. A two-level supply chain model is developed, consisting of a core enterprise and suppliers, initially analyzed in a non-contractual environment. The findings reveal inefficiencies in supply chain coordination under these conditions, prompting the design of a cost-sharing and profit-sharing contract model. By applying these contracts, supply chain coordination is significantly improved, leading to enhanced collaboration, optimized resource allocation, and increased profitability for all stakeholders. The innovative contribution of this research lies in its integration of data elements with contractual coordination mechanisms, which is verified through practical case studies and numerical simulations, offering a novel perspective and methodology for managing construction industry supply chains.
