企業永續責任

1. Stakeholder Identification

HDRE values communication with its stakeholders and upholds the principles of openness and transparency by providing diverse communication channels to facilitate effective two-way engagement. The starting point for stakeholder identification is based on the parties encountered through the daily operations of each department within HDRE. Following the AA1000 Stakeholder Engagement Standard (AA1000 SES), HDRE assesses stakeholders based on five dimensions—dependency, responsibility, tension (concern), influence, and diverse perspectives—to identify eight key stakeholder groups.
The stakeholder groups are ranked in the following order of importance: employees, customers, government agencies, shareholders and investors, suppliers and contractors, media, communities, and NGOs/research institutions. In addition, HDRE maintains ongoing engagement with industry associations through policy dialogue, training, and industry exchange.

2. Stakeholder Engagement

HDRE has established diverse communication channels for stakeholders to better understand their attitudes, perspectives, and issues of concern. The Company regularly reviews and adjusts its business strategies in response to stakeholder feedback and expectations. Through proactive engagement with stakeholders, HDRE strives to create mutual benefits and achieve sustainable business operations.
