The last decade has witnessed different price trajectories in the international and Chinese agricultural commodity markets. This paper compares and contrasts these dynamic patterns between markets from the perspective of price bubbles. A newly developed right-tailed unit root testing procedure is applied to detect price bubbles in the Chicago Board of Trade (CBOT) and Chinese agricultural futures market during the period 2005-14. Results show that Chinese markets experienced less prominent speculative bubbles than the international markets for its high self-sufficiency commodities (wheat and corn), but not for low self-sufficiency commodities (soybean). The difference in price behavior is attributed to differences in market intelligence, and to Chinese agricultural policies related to trade as well as domestic government policies. Besides, it discusses challenges to the sustainability of the stable price trajectory in Chinese markets.Au cours de la dernière décennie, les prix des produits agricoles sur les marchés chinois et international ont suivi des trajectoires variées. Dans le présent article, nous comparons les divers marchés sur le plan des bulles de prix des produits agricoles. Nous avons utilisé un nouveau test de racine unitaire qui exploite la queue de droite de la distribution de la statistique pour déceler les bulles de prix des produits agricoles sur le Chicago Board of Trade (CBOT) et sur les marchésà terme chinois au cours de la période 2005-14. Les résultats de notreétude montrent que les marchés chinois ont connu des bulles spéculatives moins prononcées que les marchés internationaux dans le cas des produits agricoles pour lesquels l'autosuffisance de la Chine est trèsélevée (le blé et le maïs), par rapport aux produits pour lesquels l'autosuffisance est faible (le soja). La différence sur le plan du comportement des prix est attribuable aux différences sur le plan de l'information commerciale ainsi qu'aux politiques agricoles chinoises en matière de commerce età la politique intérieure du pays. Nous avonségalement examiné les défis par rapportà la durabilité d'une trajectoire de prix stables sur les marchés chinois.

AbstractPurpose -The purpose of this paper is to examine the impact of two Chinese cultural constructs, guanxi (networks) and xinyong (interpersonal trust) in the burgeoning vegetable supply chains. Design/methodology/approach -Data were collected using a validated survey instrument and 520 usable responses were obtained from vegetable farmers in three main vegetable producing provinces of China. Findings -The findings revealed that farmers' guanxi promotes xinyong and collaboration of buyers. It was also determined that xinyong is the key mediator between guanxi and the two outcomes, loyalty and financial performance of farmers. Additionally, xinyong influences collaboration of the buyer. Research limitations/implications -This paper offers strategic insights into both academicians and practitioners associated with the vegetable industry regarding enhancement of inter-organisational relationships (loyalty) and financial performance of farmers in China through the embedded concepts of guanxi and xinyong. Originality/value -Despite its potential importance, relatively little is known about these two concepts especially with respect to supply chains of fresh produce.
