Özet (Çeviri)
Problem Situation and Motivation: In contrast to the vast amount of literature into ecommerce, research on e-government is still in its infancy. There is a crucial need for egovernment specific research that addresses the distinctive nature and unique complexities surrounding it. In particular, citizens' needs have to be taken into account in e-government practice. In contrast to frequent use of social media, e-commerce and online banking, the lack of interest towards e-government services on the demand side has resulted in more specific research to increase understanding of adoption factors within the last decade. Furthermore, espoused cultural values are shown to influence the adoption behavior of nations therefore the adoption of e-government needs to be examined from the perspective of national culture. Yet, most of the prior research in this context was conducted in the U.S., which is distinct from Europe with regards to cultural characteristics. Purpose: The objective of this thesis is to investigate and understand the determinants of G2C e-government adoption in a cross-cultural context. Since prior research has not examined egovernment adoption behavior of the German nation by testing a theoretical model with a representative sample, the primary objective of this thesis is to shed light on the citizens' perspective in Germany by examining the salient determinants of adoption. Being at a similar stage of economic growth and having similar technological infrastructures, Sweden, which enjoys leadership rankings in G2C e-government benchmarks, was selected as a culturally distinct European nation for comparison with Germany. Methodology: This work combines descriptive and explanatory research in order to provide a comprehensive understanding of G2C e-government adoption. Preceding the confirmatory research, a descriptive study was conducted in Germany utilizing a nationwide representative sample to investigate the determinants, barriers and concerns influencing citizens with regard to e-government services. Insights gained from this descriptive study enabled the selection of the appropriate model for the research context and the nations of analysis. This research instrument, which integrates trust and risk perceptions into the Rogers' Diffusion of Innovations Theory, was validated using covariance based structural equation modelling (SEM). Besides examining national differences by conducting multi-group comparisons, the research model was also tested to reveal differences between demographical groups as well as between online tax filing users and non-users. The confirmatory research was followed by two descriptive studies, which enabled the observation of possible changes in the adoption behaviors of citizens over time. Findings: The four consecutive descriptive studies showed that the factors and barriers related to security, data protection, and reliability play an important role in decision making of citizens. In accordance with the a priori theoretical expectations, the German respondents were observed to have greater concerns than the Swedish respondents confirming the relatively higher uncertainty avoidance index of the German nation. Compatibility, perceived risk, relative advantage, complexity and subjective norm were found as antecedents of the adoption of online tax filing in Germany, which should be considered by the Federal Government in the future. The findings also indicated that citizens expect to see clear benefits from G2C e-government over traditional methods of interaction with public authorities. Factors related to usability and technical support were found to be important in Germany, but considered less important in Sweden. The multi-group moderation analysis in SEM showed that demographical groups differed in terms of the determinants of G2C e-government adoption. Theoretical Contributions: This dissertation makes contributions to the G2C e-government literature, trust research and cross-cultural research at several levels. Considering that the German speaking IS community was criticized for focusing heavily on high relevance and having poor rigor by IS scholars, this dissertation provides an important contribution to G2C egovernment literature. Although multi-group SEM is recognized as a reliable method for crossnational research, a few papers in this area were published in major IS journals, which is a distinguishing aspect of this thesis in terms of its rigor. Furthermore, this thesis aims to offer an important empirical contribution as well, by employing representative samples in four comprehensive empirical studies conducted in two European countries, weighted by central features of gender, age and formal education. The theoretical contribution of this work should also be emphasized considering the lack of studies on theory testing in G2C e-government literature. It is the first theory-based study which investigates salient determinants of G2C e-government adoption by the German citizens. Furthermore, this thesis recognizes the multidimensional nature of trust and addresses the role of trust in G2C e-government context, which remains relatively under-researched. Finally, since most of the IS adoption and trust literature is based on studies conducted in the U.S., this thesis contributes to e-government literature and cross-cultural research by a comprehensive analysis comparing adoption behaviors of two developed European nations. Practical Implications: This dissertation provides valuable insights into the citizen perspectives on e-government adoption, which has not received much research to date. The comprehensive analysis indicated that citizens of Germany and Sweden have different perceptions regarding adoption of G2C e-government services. The outcome of this research facilitates a broader understanding of G2C e-government adoption in the German nation, which should support the Federal Government in reaching its goal of widespread adoption of egovernmentservices. A further contribution to practice is the identification of factors, barriers and concerns of different user groups distinguished by gender, age and formal education which sheds light into to the differences of demographic groups in E-Government. Limitations: Three limitations of this study should be addressed in future research. This study utilizes Hofstede's cultural dimensions as the cultural framework which is premised on the assumption of cultural homogeneity within a given country and this may not hold. Second, only households having a PC and those with Internet access were considered in this research due to the selected data collection method. Third, although Sweden and Germany are both highly developed countries with advanced telecommunications infrastructure and economic welfare, culture may not be the only reason for the differences between the nations.
