Abstract

Using the Structure–Conduct–Performance (SCP) framework, this study aims to evaluate the structure, behavior, and performance of the Indonesian e-commerce industry, and to explain its impact on consumer welfare. The research method used is a descriptive qualitative approach. Stakeholders in this study consist of business competition regulators, e-commerce platform managers, micro, small, and medium enterprises (MSMEs), and consumers residing in the cities of Jakarta, Bandung, and Surabaya. To identify patterns related to the SCP dimensions, data were collected through observation, interviews, and review of industry documents. The results show that the Indonesian e-commerce market structure tends to be concentrated among a few large players that control significant market share. Intensive promotional strategies, integration of logistics and payment services, and utilization of data for personalization and algorithms are examples of companies' competitive behavior. These conditions result in market performance, which provides benefits to customers in the form of competitive prices, product variety, and ease of distribution. However, there are also risks, such as potential predatory practices, dependence on promotions, limited choice due to market consolidation, and data privacy. According to this study, although e-commerce in Indonesia offers short-term welfare benefits for consumers, digital competition oversight policies, algorithmic transparency, and support for MSMEs are needed to achieve a balance between innovation and consumer protection.

Abstract

International trade is trade carried out by residents of a country with residents of other countries on the basis of a mutual agreement. One of the things that determines a country's economic growth is international trade which includes export-import activities. One advantage of international trade is that it allows a country to specialize in producing goods and services at low prices. This study aims to determine the effect of international trade on Indonesia's economic growth. The research method used to solve this problem is a quantitative method using multiple regression analysis and the classic assumption test from secondary data sourced from North Sumatra Economic Data (2001-2020). The results of this study are 1. Partially, imports have a significant positive effect on growth. Economics with the acquisition of a Prob. value of 0.0002 < apha 0.05 so that ha is fulfilled or ho is rejected and for the positive direction it is proven by the Coeffcient which is negative (1.216780). 2. Partially, exports have a negative but not significant effect on economic growth due to the acquisition of a Prob.0.2268> alpha 0.05 value so that ho is fulfilled or ha is rejected and for a negative direction it is proven by a negative Coefficient. (-0.448407) 3. Simultaneously Export and Import have a significant effect on Economic Growth with the acquisition of a Prob (F-Statistic) value of 0.00000 <0.05 meaning that the two variables significantly influence Economic Growth so that ha is fulfilled or ho is rejected 4. The Adjusted R-Square is 0.89, which means that much the two independent variables affect the dependent variable, namely GRDP, which means that there are still other models that affect the dependent variable.
