반도체 성과급...청주 ‘소비’로, 이천에선 ‘집’으로

Survey analysis reveals that consumption in the semiconductor-friendly regions of Ichon, Hwasong, and Cheongju is significantly higher compared to other regions, growing by approximately 4%. This increase is primarily due to the flow of earnings from the semiconductor industry into housing markets, as seen in Cheongju and Ichon.

According to the Korea Bank Research Group's comprehensive team, the difference in impact lies in how much of the earnings are channeled into the housing market. The study analyzed the spillover effects of earnings generated by Samsung Electronics and SK-Hynix semiconductor companies on consumer spending. The analysis showed that over the past six months (from January of last year to June of this year), consumer spending in semiconductor-exposed areas (Ichon, Hwasong, and Cheongju) increased by 3.7% compared to other regions, mainly due to high-value discretionary spending on cars, household appliances, and department stores.

The research team assessed the semiconductor boom as having a significant positive impact on domestic consumption. Card data analyzed by consumption flows revealed significant differences between semiconductor-producing regions. In Cheongju's Hyeongdeok-gu and Hwasong City, consumer spending remained above the national average. In contrast, Ichon City and Pyeongtaek City showed similar patterns to the rest of the country, while Ungjin Gyeonggung showed relatively lower performance.

Comparing the increase in card usage from 2022 to 2024, Hwasong and Cheongju recorded a 2.6% and 2.5% increase, respectively, while Ichon (-0.3%), Pyeongtaek (-0.4%), and Ungjin Gyeonggung (-0.8%) lagged behind the national average. This difference was attributed to the housing market impact of earnings in Ichon. For Hwasong and Ungjin, various factors such as the timing of earnings disbursement were considered.

The research team noted that product-wise, semiconductor-producing regions showed strong sensitivity to income changes, particularly in high-value discretionary spending, indicating the potential for increased consumption due to the semiconductor boom. The team estimated that accumulated consumption growth from last February to this June totaled 1.11 trillion won, with an estimated 1.7 trillion won by the end of this year if the current pattern continues.

This consumption increase amounted to 8 trillion won annually, representing 2% of last year's private consumption growth (+41 trillion won). The domestic value-added effect of this consumer growth was estimated at 0.01% for 2025 and 0.03% for 2026 using industrial association analysis. While not enough to determine overall growth rates, the research team highlighted that the "company performance → wage → consumption" spill-over effect was beginning to work, signaling real progress in the chain reaction initiated by significant earnings payouts.
