| Resumen en español | Este artículo tiene como objetivo presentar los factores que inciden en la localización de los servicios intensivos en conocimiento en la Zona Metropolitana del Valle de México. Para ello se utilizan los datos del Directorio Nacional de Unidades Económicas agregados a nivel de código postal, y usando técnicas de regresión Hurdle, cero-infladas de tipo Poisson y negativa binomial, se muestra que estas actividades se localizan principalmente donde existe una densidad importante de empresas así como una diversidad de las mismas. Igualmente, se encontró que la distancia a vialidades y a las estaciones del metro son estadísticamente significativas. Esto apunta a economías de aglomeración tanto de localización como urbanas |
| Resumen en inglés | Assumptions Knowledge-intensive companies are recognized as value-creating agents. In fields such as urban economy and economic geography, the location of companies has been a recurring subject. The location of these companies and the conditions that define this location in either the urban or intra-urban system are relevant issues. In the urban system, these activities take place primarily in the largest cities or in those where the local conditions propitiate their establishment. Within cities (the central topic addressed in this article), urban or localization economies have been discussed to explain the existence of a certain spatial pattern. Another aspect proposed is the existence of de-concentration of these activities from the center to the periphery of cities. Despite being a topical subject, this has been barely explored in developing countries, likely as a consequence of the availability of information together with certain reluctance to analytical frameworks. The objective of this article is to contribute to the knowledge about the intra-urban location of knowledge-intensive services in the Valley of Mexico Metropolitan Zone (VMMZ). Data and Methodology Company data were obtained from the 2019 National Directory of Economic Units (DENUE). We used Subsectors 51 to 56 of the 2018 North American Industrial Classification System (NSCIAN). These include information activities in mass media, financial services, real estate, professional, corporate, and business-support services. The number of economic units in knowledge-intensive services were grouped by postal code, i.e. we established the total number of companies for each postal code in the VMMZ. The covariables (measured at the postal code level) that would explain the location of these companies were: average education level, economic diversity (Shannon entropy index), density of economic units (log-transformed), population density (log-transformed), distance to Mexico City center downtown squ |
