Zip-Code Level Analysis of Industry Input-Output and Knowledge Levels in San Antonio, Texas

Abstract
Economic activity can be studied using network analysis. In this methodology, the primary objective is to understand the relationships between economic entities. However, most studies in this emerging field of multidisciplinary study tend to focus on high-level aggregations such as trade between nations or communications between authors, or other social constructs. This research uses network analysis to better understand the number and types of economic relationships within a prescribed area of a city (San Antonio, Texas), which should help describe the productive structure and employment needs and thus the economic vitality of the neighborhoods that comprise an urban area. We isolate segments in San Antonio, Texas using ZIP Code-level data and study these with new techniques and technology-based tools to compare two segments of the urban area. We find preliminary evidence that connectivity and knowledge play an important part in urban development.
