This study examines the impact of innovation at the strategy level on innovation at the process and system levels, which are considered to be forms of function-level innovation, based on the strategy implantation approach. The study also reveals the effect of process and system innovation on the sustainable competitive advantage (SCA) of young firms in Vietnam. The research used primary data from a survey of 289 young firms’ leaders in Vietnam. PLS-SEM using SmartPLS software was employed to assess the ability of the measurement model and structural model to test hypotheses. The findings indicated that the four hypotheses about the effects of strategy innovation on process and system innovation and the effects of process and system innovation on the SCA of young firms in Vietnam were all confirmed. These crucial results fill the research gap of innovation in young firms, especially the gap in the context of developing countries. The current study addresses an important implication for the use of innovation practices in young firms to sustain the firm’s SCA. Accordingly, young firms are able to significantly strengthen their sustainable competitive advantage through innovation practices at both strategy and function levels.

This study investigates the antecedents and consequences of investor trust in the Vietnamese stock market, an emerging economy where individual retail investors dominate trading activity and the regulatory environment is still maturing. Drawing on institutional theory, behavioral finance, signaling theory, and cognitive trust theory, an integrated structural model is proposed in which three factors: regulatory and supervisory framework, investor financial literacy, and listed firm image, are hypothesized to influence investor trust, which in turn is expected to affect investment performance. The empirical analysis is based on survey data collected from a sample of young individual investors and students in Vietnam, a cohort that is particularly relevant given the post-pandemic surge in first-time retail participation, and the data are analyzed using partial least squares structural equation modeling (PLS-SEM). The results reveal that all three antecedent constructs significantly and positively affect investor trust, with listed firm image emerging as the strongest predictor, followed by the regulatory and supervisory framework and investor financial literacy. Investor trust, in turn, is shown to be a strong positive determinant of investment performance. The structural model exhibits substantial explanatory power, with R² = 0.610 for investor trust and R² = 0.558 for investment performance, indicating that the model accounts for a substantial share of the variance in these endogenous constructs. The findings extend the trust-investment literature to an emerging-market context, highlight the predominance of firm-level over institutional cues in shaping the trust of young Vietnamese investors, and offer practical implications for regulators, listed firms, and financial educators seeking to strengthen market participation and efficiency in Vietnam.

Agricultural development in Vietnam has experienced substantial changes since the 1980s, propelled by crucial land policy reforms. The Vietnam Ministry of Agriculture and Rural Development (MARD) [1] and the 1993 Land Law jointly transformed Vietnam from a community farming model to a market-oriented agricultural economy. This research use econometric analysis combined with a historical approach to assess the effects of these policies on agricultural productivity and rural livelihoods. Significant findings indicate a 67% enhancement in land productivity from 1990 to 2010, alongside a consistent rise in agricultural output, with annual growth rates of 5.9% from 1990 to 2000 and 4.2% from 2000 to 2008. Nonetheless, land fragmentation, impacting 85% of agricultural households with less than 1 hectare, constitutes a significant obstacle, diminishing rice income and constraining economies of scale. This study underscores the imperative for policies that promote land consolidation, equitable resource access, and financial inclusion to sustain agricultural prosperity in Vietnam and offer insights for transitional economies worldwide.
