Investigating barriers to blockchain adoption in construction supply chain management: A fuzzy-based MCDM approach

Technological Forecasting and Social Change, Journal Year: 2023, Volume and Issue: 196, P. 122849 - 122849

Published: Sept. 25, 2023

This study aims to investigate the barriers adoption of Blockchain Technology (BT) within field Construction Supply Chain Management (CSCM) by unravelling their interrelationships. In doing so, a Pythagorean fuzzy-set-based DEMATEL method assess these in complex environment is proposed. The results suggest that "market-based risks", "high costs for maintaining sustainability", and "usage underground economy" are most influential BT CSCM. Furthermore, identifies "inadequate knowledge/employee training", "contractual risk", "scalability issues" play pivotal role CSCM system. reliability validation obtained were also shown using sensitivity analysis focus-group-discussion approach. findings this provide valuable insights stakeholders construction industry design implement effective measures overcome identified By addressing barriers, can facilitate BT, leading more efficient supply chain management practices.

Establishing the relationship between the strategic factors influencing blockchain technology deployment for achieving SDG and ESG objectives during infrastructure development: an ISM-MICMAC approach

Smart and Sustainable Built Environment, Journal Year: 2024, Volume and Issue: 13(3), P. 711 - 736

Published: March 22, 2024

Purpose Implementing blockchain in sustainable development goals (SDGs) and environmental, social governance (ESG)-aligned infrastructure involves intricate strategic factors. Despite technological advancements, a significant research gap persists, particularly emerging economies. This study aims to address the challenges related SDGs ESG objectives during delivery remain problematic, identifying evaluating critical factors for successful implementation. Design/methodology/approach employs three-stage methodology. Initially, 13 are identified through literature review validated by conducting semi-structured interviews with six experts. In second stage, data were collected from nine additional final undergoes analysis using interpretive structural modeling (ISM)–cross-impact matrix multiplication applied classification (MICMAC), aiming identify evaluate independent dependent powers of driving implementation objectives. Findings The study’s findings highlight three crucial successfully integrating technology (BT) into goals: security (F4), identity management (F8) supply chain (F7). unravels these factors, hierarchical relationships dependencies applying MICMAC ISM techniques, emphasizing their interconnectedness. Originality/value highlights integration SDG ESG-aligned development, offering insights policymakers practitioners while importance training support advancing practices.

Investigating the mechanisms of sustainable urban land renewal: A perspective of spatial development rights

Sustainable Cities and Society, Journal Year: 2024, Volume and Issue: 109, P. 105536 - 105536

Published: May 19, 2024

Urban renewal, as an important means of promoting sustainable urbanization in the stock era, is essentially a process redistributing land appreciation benefits caused by spatial development rights. However, current literature mostly analyzes traditional two-dimensional renewal model from perspective market mechanisms, which leads to inability urban mechanisms adapt development. Therefore, taking Shenzhen example, our study aims understand mechanism three-dimensional Using geographically weighted regression and two-stage least squares regression, we found that objective value analysis has shifted common minimum unit local space. Moreover, affected surrounding environment various supporting public service facilities, existence heterogeneity significant differences different functional space within same geographical ranges. The influence intensity economy, society, shows decreasing pattern center region outer circle region. We not only construct framework based on property rights, but also distinguish endogenous issues for spaces. Our could make great difference adjustment rights acquisition.

Against the background of accelerating climate change, this paper examines to which extent sustainable infrastructure finance can effectively contribute European heat transition as a part "Great Transformation" towards neutral economy and society. Since building sector is responsible for approx. 35% EU's carbon footprint, district heating cooling networks provide an efficient technology decarbonizing energy supply buildings. New allows hot water generation that combustion free. A large-scale role-out would require hundreds billions EUR investments within next few years. In view high public debt, will not be able required investment volumes. regulatory changes, such EU Action Plan on Financing Sustainable Growth, in way financial markets participants might fill funding gap. particular focus lies blended finance, since related instruments reduce investors' risks, esp. early stages lifecycle. Due improved risk-return-relationship makes more attractive private investors. It also essential investors understand kind business model they invest in. Therefore, we discuss importance key performance indicators four dimensions are relevant decision-making process: return, risk, liquidity sustainability.
