Hanehalkı Gıda Tüketim Modelinin Analizi: Çin Örneği

Bu çalışma 3 farklı gıda kategorisindeki tüketim modelini analiz etmektedir. Tahıl, et ve deniz ürünleri, Çin’in Jiangsu ve Guangdong şehirlerindeki hane halkının tüketim modelini analiz etmek için seçilmiştir. Gelir esnekliği, ürünün kendi fiyat esnekliği ve çapraz fiyat esneklikleri Doğrusal Harcama (LES) ve Dolaylı Translog Talep Sistemleri (ITDS) aracılığıyla tahmin edilmiştir. Ayrıca, çalışmada hane halkının tüketim modellerini belirlemek için analize bir de ekonomik değişken eklenmiştir. Böylece, ITDS modeli ekonomik değişken eklenerek ve eklenmeden de analiz edilmiştir. Analiz sonuçlarına göre, gelir esnekliği en yüksek deniz ürünlerinde iken, en düşük tahıllarda bulunmuştur. Ürünlerin kendi talebinin fiyat esneklikleri baz alındığında balık ve et ürünleri yüksek esnekliklere sahiptir. Bu nedenle gerek tüccarlar gerekse politika yapıcılar, söz konusu ürünlerin gelecekte karlılığı sürdürülebilirliğine dair daha dikkatli olmalıdırlar.

Anahtar Kelimeler:

Tüketim modeli, Esneklikler, Doğrusal Harcama Sistemleri, Dolaylı Translog Talep Modeli

Analysis of Household Food Consumption Pattern: An Application for China

This study analyzes consumption pattern of three aggregated food categories for households in China. Grain, meat products and aquatic products are chosen to understand consumption pattern in Jiangsu and Guangdong provinces in China. The Linear Expenditure (LES) and Indirect Translog Demand Systems (ITDS) implemented to estimate income elasticities, own price elasticities, and cross price elasticities of these food categories. In addition to that an economic variable is used in the system to explain impact on household consumption pattern, so ITDS with and without economic variable are also examined. Analysis results show that fish have the highest income elasticities among others, while grain has the lowest income elasticity. According to high own price elasticities of fish and meat products traders and policy makers should be more circumspect to maintain profitability.

Keywords:

Consumption Patterns, Elasticities, Linear Expenditure System, Indirect Translog Demand System,
