Subproject 46
Electronic Invoice Information System
The general objective of subproject 46 is to systematize the construction of indicators, analysis methods and economic models for the region affected by the disaster based on purchase and sale information from electronic invoices (NFe).
This objective is divided into:
- Map the flows of purchase and sale of goods and services by product groups based on the modeling/segmentation of FNs, in order to identify and quantify the main debt and credit chains according to their relevance in the affected region;
- Municipal georeferencing of purchase and sale of goods and services by product groups;
- Evaluate the NFe database of Minas Gerais in terms of sectorial and regional coverage, defining the necessary aggregations for its use in economic studies;
- Implement a segmentation of products/sectors and regions to be used in the other stages of the project;
- Build a matrix for the purchase and sale of goods and services, with the statistical quantification of the volume of transactions by types of products/services, regionalization of flows with origin and destination in the affected municipalities;
- Georeferencing of the purchase and sale of goods and services matrix;
- Develop an indicator of Economic Activity Level in the affected municipalities, with the objective of ascertaining the evolution of the level of economic activity in the period of interest (before and after the disaster);
- Develop an activity index from secondary data and another from NFe data, enabling the validation of the results obtained;
- Georeferencing of the Economic Activity Level in the affected municipalities;
- Develop and test a price monitoring methodology based on the NFe, which in other projects can be used to develop a price index in the affected municipalities.
Methodological Steps
1st Stage - Exploratory and descriptive analysis of the NFe's database
2nd Stage - Municipal economic activity indicator based on secondary data
3rd Stage - Elaboration of the Trade Matrix and production chain
4th Stage - Proposition of a Price Index calculation methodology
