패널 자료 분석을 활용한 유통업자 상표 이용도와 점포 충성도의 관계 = The Relationship between Private Label Brand Share and Store Loyalty by Applying Panel Data

국문 초록 (Abstract)

기술의 발달 및 소비 패턴의 변화, 다양한 채널의 진입 뿐 아니라 채널 간 경계가 없는 무한 경쟁 체제 속에서, 유통업체들은 점포의 차별화와 수익성 제고를 동시에 실현 시킬 수 있는 전략적 무기이자, 이를 통해 궁극적으로 고객의 점포에 대한 충성도를 이끌어낼 수 있는 효과적인 수단으로 PB 개발 및 확대에 많은 투자를 하고 있다. 그러나, PB는 정말 점포 충성도 제고에 도움이 되는 것일까? 그리고 도움이 된다면 다른 어떤 요인들이 이 관계를 더욱 강화시킬 수 있을까? 본 연구는 이와 같은 질문에서 시작되었다. 이를 확인하기 위해 본 연구에서는 기존의 연구들과는 차별적으로 닐슨코리아에서 관리‧축적하고 있는 2,000여명의 패널들의 3년간의 FMCG 구매 데이터를 기반으로 주요 변수들을 계산하였으며, 설문 조사를 병행하여 데이터의 구조와 완성도를 높였다. 가설 검정은 2SLS(Two Stage Least Squares)방식을 사용하였다. 대형마트를 중심으로 한 본 연구에서 PB구매 비중과 점포 충성도간의 관계를 확인해 본 결과, 특정 점포에서의 PB 구매가 높아질수록 점포에 대한 충성도는 높아지며, 점포의 충성도가 높아질수록 해당 점포에서의 PB구매 비중 역시 높아짐을 알 수 있었다. 그리고 이 두 변수간의 관계에 대한 조절변수로 카테고리에 대한 관여도, PB의 품질, 그리고 고객들의 멀티채널 이용수준을 상정하고 그 조절효과를 분석해 본 결과, 각 변수의 조절효과는 대형마트 3사마다 조금씩 다르다는 것을 확인하였다.

The three most significant changes within the domestic retail business that have happened over the past 30 years are as follows. First, the increase in scale along with offering of multi-channel. Second, the power shift from that of the manufacturers to that of the retailers. Third, the development and strengthening of private label (PB) by retailers. Technology development, entry of various channels and changes in consumption patterns have led to infinite competition which has no channel boundaries. In such extreme competition, retailers are encouraged to invest heavily in development and expansion of PB as a strategic weapon to realize store differentiation and profitability at the same time. This is also an effective way to ultimately acquire customer loyalty.
Although the introduction and development of PB in Korea are slower than in developed countries in Europe and North America, most channels including hypermarket, convenience store, TV home-shopping, supermarket, on-line shopping mall, and mobile commerce have actively introduced and developed PB in recent years, which requires research on PB from diverse perspectives. However, the proportion of research that confirms factors influencing PB performance is high but there is little research regarding the ultimate purpose of operating PB, despite that the retailers take the risks.
In this study, we extended the scope of the research topic of PB and investigated the relationship between PB purchasing behavior of consumers and loyalty to the retailer. The moderating effect of the involvement of product category, the quality level of PB and customers’ tendency of multi-channel usage on the relationship between PB share and loyalty to the store have been identified as well. Unlike most preceding studies, we took a three-year FMCG purchasing data of 2,350 panelists among various channels, managed and accumulated by Nielsen Korea. Instead of conducting a survey which measures customers’ level of perception and purchase intention, we calculated store loyalty to a particular store as share of wallet (SOW) which shows the ratio of spending in a particular store to total spending of the household across the stores.
We also conducted a questionnaire survey targeting the same panels and matched the questionnaire results with purchasing data to enhance the structure and completeness of the data set. The stores are set into 14 different categories, and the big 3 hypermarkets’ data are mainly used for analysis as they are the key players to enlarge PB market in Korea and they have more categories that offer PB. In addition, their PB shares are higher than average and they have on-line channels as well.
The analysis unit of this study is the individual panels in a given year. Store loyalty to a particular store is defined as the share of wallet (SOW). In addition, the share of items purchased and the share of shopping trips have also been used as alternative indicators of store loyalty to observe the relationship between PB share and store loyalty from various perspectives. Since it was already proven from many previous researches that PB share and store loyalty have an interdependent relationship, we implemented the 2SLS (Two Stage Least Squares) Method to investigate the causal relationship between two variables (see [Equation 1 & 2]. As for competing hypotheses set to verify the direction between PB share and store loyalty, PB share has positive effect on store loyalty and store loyalty also has positive effect on PB share (see <Table 1>).
We also investigated these relationships on the basis regarding the share of number of items purchased and the share of purchasing frequencies which are known as other measures for behavioral loyalty. In both cases, PB share has a positive effect on store loyalty(based on number β=0.112, t=3.588 / based on frequency β=0.112, t=3.539), as well as store loyalty positively effecting PB share(based on number β=0.107, t=4.849 / based on...
