The explosive growth of mobile Internet services in Japan has generated great interest in understanding the reason for success. Given that the diffusion ratios of these services differ according to the countries, some studies suggest that a series of requirements must be met, and others propose that culture is one of the main factors. In addition, it is important to mention that research work to develop a model that integrates the elements that intervene in the supply and demand of these services and help us understand the reason for their adoption are still scarce. To reduce this gap, the objective of this article is to propose an integral model from the point of view of the demand and supply of the elements that intervene in the adoption of these services. For its development, a set of theories is considered: dissemination of innovations, electronic commerce, and mobile commerce, use o...

Several authors consider the environment variable to be an influential element on the innovation variable, but they do not provide further insight of the dimensions of these variables. This study, applied to a sample of service companies, includes dimensions of environment (uncertainty and complexity) and dimensions of innovation (technical and administrative), as well as organizational characteristics as a moderating variable in this relationship between environment and innovation. The results indicate that an uncertain environment promotes only technical innovation, while a complex environment promotes both administrative and technical innovation. It was also found that organizational characteristics partially moderate the relationship between the two variables.

This paper examines the factors associated with the adoption of electronic commerce and the relationship between these factors and the degree of implementation of this technology in medium-sized companies in Peru. It does so base on the empirical evidence provided by companies that represent successful experiences in the use of electronic commerce. Also, in response to the need to use a unit of measurement different from the binary one adopts/does not adopt to establish the degree of implementation of the technology of electronic commerce, this research presents a measurement proposal that considers four dimensions: volume, diversity, amplitude, and depth. The framework of analysis comes from the theory of the diffusion of innovations.

Este trabajo examina los factores asociados con la adopción del comercio electrónico y la relación entre estos factores y el grado de implementación de esta tecnología en empresas medianas en el Perú. Lo hace a partir de la evidencia empírica proporcionada por empresas que representan experiencias exitosas de uso del comercio electrónico. Asimismo, como respuesta a la necesidad de emplear una unidad de medida diferente de la binaria adopta/no adopta para establecer el grado de implementación de la tecnología de comercio electrónico, esta investigación presenta una propuesta de medición que considera cuatro dimensiones: volumen, diversidad, amplitud y profundidad. El marco de análisis proviene de la teoría de la difusión de innovaciones

El crecimiento explosivo de los servicios móviles de Internet en el Japón ha originado gran interés en entender el porqué del éxito. Dado que los ratios de difusión de estos servicios difieren según los países, algunos trabajos sugieren que deben cumplirse una serie de requisitos y otros proponen que la cultura es uno de los principales factores. Además, es importante mencionar que aún son escasos los trabajos de investigación para desarrollar un modelo que integre los elementos que intervienen en la oferta y demanda de estos servicios y ayuden a entender el porqué de su adopción. Para reducir esta brecha, el objetivo de este artículo es proponer un modelo integral desde el punto de vista de la demanda y oferta de los elementos que intervienen en la adopción de estos servicios. Para su desarrollo se considera un conjunto de teorías: difusión de innovaciones, comercio ele...
