And there was 1 independent variable, as the wholesale amount of rose apple by air (Q_air_t), was the variable correlated in the opposite direction with 99 percent confidence level. An 1 percent increase of the wholesale amount of rose apple by air (Q_air_t) leaded to an 0.0165567 percent increase of the wholesale price of rose apple (Price_air_t).  2. In the shipping period that lasted for 3 days, the factors affecting price determination of Thabthimjan Rose Apple with statistically significant were as follows: the wholesale amount of rose apple by air (Q_air_t) the wholesale price of rose apple by air of last day (Price_air_t-1), the period of the memorial day and the worship needed festival (Festival_t) and the wholesale amount of rose apple by land(Q_land_t). The result showed that there were 2 independent variables, as the wholesale price of rose apple by air of last day (Price_air_t-1) and the period of the Memorial Day and the worship needed festival (Festival_t), were the variables correlated in the same direction with 99 percent and 95 percent confidence level respectively. An 1 percent increase of the wholesale price of rose apple by air of last day (Price_air_t-1) leaded to an 0.736323 percent increase of the wholesale price of rose apple (Price_air_t). And if the wholesale day is in the period of the Memorial Day and the worship needed festival (Festival_t), it leaded to a 6.14157 Yuan increase of the wholesale price of rose apple (Price_air_t). And there was 2 independent variable, as the wholesale amount of rose apple by air (Q_air_t) and wholesale amount of rose apple by land(Q_land_t), was the variable correlated in the opposite direction with 99 percent confidence level.
