This study examines the impact of renewable energy consumption, CO₂ emissions, and renewable electricity generation on the Sustainable Development Index in Uzbekistan over the period 1990–2023. Using an autoregressive distributed lag (ARDL) model, the study estimates the short- and long-run relationships between these variables. The Sustainable Development Index is constructed using indicators of primary school enrollment, life expectancy at birth, and female labor force participation using a min-max normalization method. The results indicate a long-run positive impact of renewable energy consumption (β = 0.0552, p < 0.05), underscoring its significant contribution to sustainable development. Conversely, renewable electricity generation has a significant negative impact in the long run (–0.0153, p < 0.01), which may be due to initial high transformation costs and short-term economic adjustments. CO₂ emissions did not have a statistically significant impact on the Sustainable Development Index. The model is robust, with no autocorrelation or heteroscedasticity issues, indicating reliable results. This study underscores the importance of strategic investments in renewable energy and offers valuable insights for policy development, thereby enhancing Uzbekistan’s sustainable development trajectory.

Abstract
Innovation marketing has emerged as a critical research domain due to rapid digital transformation, evolving consumer behaviors, and increasing sustainability demands that fundamentally reshape modern business strategies. However, the intellectual structure and thematic evolution of this interdisciplinary field remain fragmented, with terminological ambiguities and isolated knowledge silos hindering theoretical development and practical advancement. This study systematically maps the intellectual structure and thematic evolution of innovation marketing research through comprehensive bibliometric analysis spanning 1972-2025. Data were retrieved from the Scopus database, yielding 10,453 scholarly documents after filtering duplicates and irrelevant materials, analyzed using the “Bibliometrix” package in R Studio with productivity metrics, citation analysis, co-word analysis, and cluster analysis techniques. The results reveal exponential growth with an annual growth rate of 11.04, particularly accelerating after 2000, with four distinct research clusters emerging: digital transformation technologies (23.4%), sustainable marketing innovations (19.8%), consumer-centric methodologies (21.2%), and strategic innovation management (18.6%). The United States leads publication volume with 1,048 documents (17.26%), followed by China with 681 documents (11.22%), while Belgium demonstrates highest citation impact with 66.15 citations per article. Notably, 67% of highly-cited articles appear in non-marketing journals, confirming interdisciplinary influence, with the most cited work by Pushpakom et al. (2018) receiving 3,064 citations. Innovation marketing has evolved from product-focused approaches toward integrated, technology-driven, and sustainability-oriented strategies, establishing itself as a distinct research domain with significant cross-disciplinary impact for marketing practitioners and policymakers.
