Forecasting of Gross Regional Domestic Product (GRDP) according to the Pematangsiantar City Business Field in 2017-2019

Understanding the Importance of Gross Regional Domestic Product (GRDP)

Gross Regional Domestic Product (GRDP) is a crucial indicator that measures the ability of a region to create added value. At the regional level, GRDP can be categorized into two types: nominal GRDP, which is calculated based on applicable prices, and real GRDP, which is calculated based on constant prices for the base year. This study aims to estimate the Pematangsiantar City GRDP value according to the business field in 2017, 2018, and 2019 using multiple exponential graduation methods.

Definition of GRDP: A Key to Understanding Regional Economic Growth

GRDP describes the overall economic value produced by all business fields in a region in a certain period. Nominal GRDP calculates total output using the current price, providing an overview of the existing economic structure. On the other hand, real GRDP aims to measure economic growth by using a fixed price from the base year, allowing for a comparison between time without being influenced by inflation. This distinction is essential in understanding the dynamics of regional economic growth and development.

The Significance of Multiple Exponential Graduation Methods in Forecasting GRDP

In this study, the analytical method used was a multiple exponential graduation method, specifically the linear method of one parameter from Brown. This method was chosen due to its ability to estimate data more accurately, especially in cases where data has a clear trend. The data used in this analysis is secondary data obtained from the Central Statistics Agency (BPS) of Pematangsiantar City. The use of this method is crucial in providing a reliable forecast of GRDP, which can inform regional economic policy and decision-making.

Results and Discussion: A Positive Trend in GRDP Growth

Based on the analysis conducted, the results obtained show that the Pematangsiantar City GRDP has increased from year to year. Both based on nominal GRDP and real GRDP, positive growth indicates the existence of good economic development in the business field in this area. The increase in GRDP also reflects the growth of economic sectors that are the backbone of the city, such as trade, industry, and service sectors. This shows that the economic policy applied can have a significant impact on local economic growth.

The Impact of Economic Policy on Local Economic Growth

The growth of GRDP in Pematangsiantar City can be attributed to the effective implementation of economic policies. The city's economic policy has focused on promoting trade, industry, and service sectors, which has led to an increase in economic activity and growth. This positive trend in GRDP growth is a testament to the effectiveness of the city's economic policy and highlights the importance of continued support for these sectors.

Conclusion: A Deep Understanding of GRDP for Regional Economic Development

From the analysis conducted, it can be concluded that the gross regional domestic product in Pematangsiantar City shows a significant increase trend between 2017 and 2019. Thus, a deep understanding of GRDP can be a reference in strengthening the regional economy and improving the welfare of the community. This study provides valuable insights into the importance of GRDP in regional economic development and highlights the need for continued research and analysis in this area.

Limitations of the Study

This study has several limitations that should be acknowledged:

Data Limitations: The study relies on secondary data obtained from the Central Statistics Agency (BPS) of Pematangsiantar City, which may have limitations in terms of accuracy and completeness.
Methodological Limitations: The use of multiple exponential graduation methods may not capture the complexity of regional economic growth, and other methods may be more suitable for analysis.
Geographical Limitations: The study focuses on Pematangsiantar City and may not be generalizable to other regions or cities.

Future Directions for Research

Future research should focus on addressing these limitations and exploring new avenues for analysis, including:

Use of Alternative Data Sources: Researchers should explore the use of alternative data sources, such as surveys or administrative data, to provide a more comprehensive understanding of regional economic growth.
Development of New Methodologies: Researchers should develop new methodologies that can capture the complexity of regional economic growth, including the use of machine learning or other advanced statistical techniques.
Expansion of the Study Area: Researchers should expand the study area to include other regions or cities, providing a more comprehensive understanding of regional economic growth and development.

By addressing these research gaps and exploring new avenues for analysis, policymakers and stakeholders can make informed decisions to strengthen the regional economy and improve the welfare of the community.
