This paper explores the factors that determine the closure or jeopardize the continuity of micro and small enterprises (MSEs). We investigated the determinants of failure from the entrepreneur’s perspective using a qualitative approach, and five variables emerged. We discovered that there are internal and external variables that impact on an enterprise’s continuity, which are themselves correlated. We applied a formula to determine which variable had a higher weight, considering values ranging from 0 to 1, and the asymmetry is to the right. The instrument was applied to 35,571 MSEs, 26,720 of which were open and 8,851 were closed. 33,576 are Mexican and 1,995 Colombian enterprises.

Our results show the lack of knowledge about the established diagnostic and treatment recommendations for Hp infection. The implementation of workshops, courses, and conferences, or the formulation of practical guidelines should be directed at primary care physicians to strengthen the practice of medicine based on scientific evidence.

Dada la importancia de las micro y pequeñas empresas, se desarrolló un estudio sobre las micro y pequeñas empresas en la economía y en particular de la Ciudad de Matamoros, Tamaulipas durante el año 2020, con los objetivos de detectar una correlación entre el grado de innovación y el desempeño, identificar el nivel de tecnología e innovación con la que cuentan las mypes y descubrir áreas de oportunidad de mejora. En este estudio se utilizó como instrumento de recolección un cuestionario, con preguntas estructuradas utilizando la escala de Likert, el cual fue aplicado a los directores de 525 mypes en la ciudad. El tipo de estudio fue cuantitativo con alcance descriptivo, correlacional, documental, transversal y un diseño de investigación no experimental. Los resultados obtenidos nos muestran una correlación débil entre la innovación y el desempeño ya que en opinión de los dueños tienen cierto grado de tecnología, la cual no aplican en sus negocios por lo cual se afecta su competitividad y desempeño. Abstract Due the importance of micro and small enterprises (MSEs), a study was developed to determine their impact on the economy, particularly, in the city of Matamoros Tamaulipas, during 2020, with the objective of detecting a correlation among the degree of innovation and performance, identifying of the level of technology and innovation which MSEs possess and identifying the areas of opportunity for improvement. This study implemented a questionnaire as a data recollection tool consisting of structured questions based on a Likert scale, which was applied to 525 MSE directors in the city mentioned above. The type of study was quantitative with a descriptive, correlational, documental, cross-sectional scope and with a non-experimental design. The results obtained show a weak correlation among innovation and performance, since, according to owners’ opinions, the enterprises have a certain amount of technology which is not applied in their business, thereby affecting their competitiveness and performance
