Furthermore, the transactional relationships between the GC and Subs in construction projects make profit-driven pursuits tempting, thereby increasing the opportunistic behaviors.\u003C\/p\u003E\r\n\r\n\u003Cp\u003EThis dissertation contributes to the body of knowledge by developing a framework based on a blockchain-enabled smart contract system to address these unethical practices, thus establishing the subcontracting process grounded on system-based trust. The proposed framework is demonstrated through a pilot test, and its feasibility and effectiveness are validated through a survey with construction professionals. The validation results show that the framework can prevent the aforementioned unethical practices and enable Subs to fairly compete for bid awards with proper budgets.\u003C\/p\u003E\r\n\r\n\u003Cp\u003EIn addition to the development of a subcontracting process leveraging a blockchain-enabled smart contract system, this dissertation contributes to the body of knowledge by 1) providing a game-theoretic framework that the GCs and Subs can use to quantify and evaluate the outcomes of their strategic behaviors (e.g., trust-driven vs profit-driven behaviors) in the subcontracting process and 2) empirically verifying the effects of system-based trust created by a blockchain-enabled smart contract system on GCs\u0026rsquo; and Subs\u0026rsquo; strategic behaviors in the subcontracting process. It verifies that the blockchain-enabled smart contract effectively promotes trust-driven behaviors by enhancing system-based trust, thereby leading to a win-win game for the GC and Subs in the subcontracting process.\u003C\/p\u003E\r\n\r\n\u003Cp\u003EThese valuable findings establish the foundation for a transformative subcontracting process that is more ethical and grounded on system-based trust. Moreover, the findings can help the construction industry deepen its understanding of the significance of trust-driven behaviors in the subcontracting process. The findings also promote the enforcement of trust-driven behaviors by enhancing system-based trust through blockchain technology.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"A Blockchain-enabled Smart Contract System for Creating System-based Trust in Subcontracting Process"}],"uid":"27707","created_gmt":"2023-02-28 18:31:34","changed_gmt":"2023-02-28 18:31:34","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2023-03-15T12:00:00-04:00","event_time_end":"2023-03-15T14:00:00-04:00","event_time_end_last":"2023-03-15T14:00:00-04:00","gmt_time_start":"2023-03-15 16:00:00","gmt_time_end":"2023-03-15 18:00:00","gmt_time_end_last":"2023-03-15 18:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"221981","name":"Graduate Studies"}],"categories":[],"keywords":[{"id":"100811","name":"Phd Defense"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78761","name":"Faculty\/Staff"},{"id":"78771","name":"Public"},{"id":"78751","name":"Undergraduate students"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}}}
