본 연구는 극조생종, 조생종, 중·만생종 양파가격을 개별 변수로 설정하여 벡터오차수정모형을 기초로 하여 Granger 인과관계를 검정하고, 충격반응분석 및 분산분해분석 및 예측을 실시하였다. 분석결과 전기 중만생종 양파생산량은 후기의 극조생종 및 조생종 양파가격에 영향을 주며, 양파와 대체관계에 있는 마늘 또한 극조생종 및 조생종 양파가격에 영향을 미치는 것으로 나타났다. 반면 중만생종 양파가격은 극조생종과 조생종 양파가격에 영향을 받으며, 조생종 양파가격 또한 극조생종 양파가격에 영향을 받는 것으로 나타났다. 즉, 전국에서 양파가 가장 먼저 생산되며, 극조생종 주산지인 제주도 양파가격이 다른 요인에 의해 가격이 변동되면, 향후 생산되는 조생종 및 중·만생종 주산지인 전남, 경남 지역 양파가격이 영향을 받는다는 것을 의미한다. 이에 따라 전기 중만생종 양파 생산이 어떠한 요인에서 생산량이 증가 혹은 감소할 때, 전국에서 가장 먼저 수확되는 제주지역 극조생종 양파가격에 대해 선제적으로 대응해야하며, 또한 어떠한 요인으로 인해 극조생종 양파가격이 상승, 혹은 하락할 때 선제적인 수급대책을 통해 향후 조생종 및 중만생종 양파가격 안정을 도모해야 할 것으로 사료된다.

In this study, to take the object of this thesis on understanding the characteristics on marketing structure and marketing distribution of landscape materials after consideration in the side of prices trends which is important factors for analysis in understanding the market of landscape materials. To do this, Analysis is divided into the prices trends. The investigation of prices trends and marketing distribution are to collect data refer to purchases and sales reports, these results are used to analyzed the operative factor of forming market structure. The periodic range of this thesis is limited from 1996 to 2000 and analytic articles is limited on 609 landscape materials(planting materials : 567 articles, facility materials : 7 articles, the other : 35 articles). The results of the whole prices trends and marketing distribution survey can be summarized as follows : 1. Prices trends of showing 3 types of landscape materials : In cases of planting, facility and the others materials, the annual average increasing rate of the index number of price was 3.1%, 3.4%, 3.1% while the KPRC(Korea Price Research Center) price was 3.98% for the past five years. 2. GSP(Government Specified Prices) Prices trends of showing 3 types of landscape materials : In cases of planting, facility and the others materials, the annual average increasing rate of the index number of price was 3.7%, 1.2%, 2.6% while the KPRC(Korea Price Research Center) price was 3.98% for the past five years. This increase indicates a small price margin, particularly, the GSP price of planting materials should be adjusted to a realistic level. 3. Native and exotic product Prices trends of showing 3. types of landscape materials : In cases of Native planting, facility and the others materials, the annual average increasing rate of the index number of price was 3.2%, 3.2%, 3.6% while cases of exotic was 3.1%, 1.0%, 5.8% for the past five years. The index number increase of prices of exotic landscape materials were fluctuated more than those the native landscape materials.

This study probed into some characteristics of the urban household such as household income, number of the household, age distribution of the family members, their characteristics of shopping behavior such as the shopping place, types of the packaging and the characteristics of the time series, using consumer panel data of the Rural Development Administration (RDA). It further examined how the above factors affect fruit purchasing prices and then estimates the degree of the influence by each factor. The study looked at the purchase of apples, pears, tangerines, and oranges - the most favorite fruits in Korea. The results of this study can be utilized as the basic information for marketing strategies and/or for the establishment of future policy plans related to fruits consumption.

Land price can be affected by convenience or psychological repulsion like PIMFY (Please In My Front Yard) or NIMBY (Not In My Back Yard) for various facilities. Services related to public establishment, welfare, medical attention, and amenities in rural areas are comparatively poorer than those in urban areas. The purpose of this study is to estimate the implications of the accessibility to community facilities in rural areas for land prices using a hedonic price model. The accessibility to facilities is estimated by real road distances and the land prices are applied for four types of land usages: field, rice paddy, building lots, and village halls. Community facilities are classified from public and community services view: education, safety, culture, transport, environment, health care, and finance. The results show that the accessibility to health care and transport can positively affect land prices and the accessibility to environment (waste facilities and junkyard) and unpleasant services (funeral hall and charnel house) can negatively affect land prices. Especially, the accessibility to hospital is the most positive influential factor for all types of land usages.

China is playing more predominant role in the liquefied natural gas (LNG) market worldwide and LNG import price is subject to various factors both at home and abroad. Nevertheless, previous studies rarely heed a multiple of factors. A time-varying parameter factor augmented vector auto-regression (TVP-FAVAR) model is adopted to discover the determinants of China's LNG import price and their dynamic impacts from January 2012 to December 2021. According to the findings, market fundamentals have a greater impact on the import price of natural gas in China than overall economic demand, financial considerations, and world oil prices. The primary determinants include domestic gas consumption, consumer confidence and other demand-side information. Then, there are diverse and time-varying spillover effects of the four common determinants on the volatility of China's LNG import price at different intervals and time nodes. The price volatility is more sensitive and long-lasting to domestic natural gas pricing reform than other negative shocks such as the Sino-US trade war and the COVID-19 pandemic. The results in this study further proves the importance of domestic natural gas market liberalization. China ought to do more to support the further marketization of natural gas prices while working harder to guarantee natural gas supplies.

The study aims to explore the impacts of types of consumer's self-construal, prices of brands, and types of discount-based sales promotion on consumers' purchase intention. For this study, a three-way mixed factor method was applied based on a formula, types of consumer's self-construal x prices of brands x types of discount-based sales promotion. The subjects were 218 females in their 20s to 30s living in seoul or Gyeonggi-do areas. For data analysis, three-way variate analysis, analysis of simple interactions and analysis of simple main impacts were conducted through use of the SPSS program. First, based on the impacts of types of consumer's self-construal, prices of brands, and types of discount-based sales promotions in the favor of consumers, there was a significant difference between higher and lower-priced brands. Second, comprehensive discounts rather than monopolistic discounts corresponded to higher favoring by consumers of interdependent self-construal. As for monopolistic discount, lower-priced products corresponded to higher favor than higher-priced ones. Third, there was a significant difference between consumers of independent self-construal and interdependent self-construal. Fourth, comprehensive discount, rather than monopolistic discount, corresponded to higher purchase intention regardless of prices of brands in the group of consumers with interdependent self-construal.

본 연구에서는 서울시 장기전세주택(SHIFT 이하 시프트)이 주변 아파트의 전세가격에 미치는 영향을 분석했다. 시프트 공급단지 5km 이내에 위치한 아파트들의 전세 실거래가 데이터를 이용하여, 시프트로 인한 주변 아파트 전세가격의 변화를 추정했다. 주요 결과는 다음과 같다. 첫째, 시프트 공급 이후 2-3km 이내 아파트들의 전세가격은 공급 이전을 기준으로 4.4% 하락했다. 반면 그 보다 근접한 1-2km 이내 위치한 아파트의 전세가격은 유의미한 변화를 확인할 수 없었다. 그 이유는 시프트 단지의 공급으로 주변지역이 함께 개발되면서 아주 근접한 아파트들의 경우 시프트 공급으로 인한 가격하락 요인을 입지환경 개선으로 인한 가격상승 요인이 상쇄한 것으로 해석된다. 시프트 단지별 분석에서는 천왕2지구1단지와 서초네이처힐 1, 3, 6단지에서는 주변 아파트 전세가격을 하락시키는 효과가 나타났다. 그러나 양재1단지, 묵동리본타워, 신내3지구2단지에서는 유의미한 효과를 확인할 수 없었다. 단지별 효과가 상이한 이유는 해당 지역의 전세수요와 시프트 공급물량 등의 차이로 인한 결과로 판단된다.
