Notes: $l n D_{t}^{m}$ ⁠, $l n P_{t}^{m}$ ⁠, lnINC_t and $l n P_{t}^{c}$ denote the logarithmic series of amount of pork consumption, pork price, average income of residents and chicken price, respectively. c is constant, t represents trend and k is lag length. The sample period covers from January 2008 to June 2009
