The.main obje.tive.of this pape. is to analyze.the.re.ationships be.we.n the.productive.proce.s and the.comme.cial trade.with wate. re.ource. use. by the.. For that the.goal is to find out, by me.ns of the.e.timation of wate. e.bodie. in the.e.porte. crops which have.the.highe.t e.port compe.itive.e.s and lowe. wate. consumption. The.finding contradicts not only the.comparative.advantage. the.ry but also the.re.ource. sustainability logic. This conclusion is de.ive. from the.gre.t e.ports of wate. via tomatoe. and low profitable.ve.e.able. from produce.s＇ pe.spe.tive.but not e.onomical from social pe.spe.tive. as shown in dome.tic re.ource.coe.ficie.t. The.dive.sion be.we.n financial and e.onomic profitability is due.to he.vily irrigation wate. subsidy. The.re.ults confirm that Jordan utilize. large.amounts of wate. in its e.ports, and in turn, it doe. not e.port goods with low wate. re.uire.e.ts. The.pote.tial saving would be.ve.y significant and agricultural se.tor ne.d to modify the.use.of wate. to a gre.t e.te.t in orde. to re.ch significant wate. savings and an e.vironme.tal sustainability. Jordan has to imple.e.t policie. that re.uce., or e.e. abandone., the.e.port and the.production of wate.-inte.sive.crops.

作者： A. S. Jabarin e. k. Al-karablieh De.artme.t of Agricultural e.onomics and Agribus#wss Manage.e.t Faculty of Ag~qc~tlture The University of Jordan P. O. Box13899 Amman 11942 Jordan

The.main obje.tive.of this re.e.rch is to e.timate.the.diffe.e.t type. of de.and e.asticitie. for the.main fre.h ve.e.able. consume. in Jordan. The.e.timate. e.asticitie. can be.use. to me.sure.the.impacts of agricultural policie. and can be.use. to pre.ict future.consumption in the.conte.t of food se.urity in te.ms of acce.s, availability, stability, and food quality. The.re.orte. de.and e.timate. we.e.obtaine. through the.e.timation of a Line.r Approximate.Almost Ide.l De.and Syste.s （LA/AIDS） for Jordan fre.h ve.e.able.crops de.and syste. using the.most re.e.t cross-se.tional data of house.old e.pe.diture.surve. in 2005. A ce.sore. re.re.sion me.hod for the.syste. of e.uations was use. to analyze.fre.h ve.e.able. consumption patte.ns. This me.hod allows for inclusion of a large.numbe. of ze.o consumption for some.foods through two-ste. de.and syste. e.timation. All of the.own-price.de.and e.asticitie. have.the.corre.t ne.ative.signs and statistically significant. According to the.e.pe.diture.e.asticity, tomato, cucumbe., and potato are.the.ne.e.sity goods. The.me.n budge. share. indicate.that consume.s spe.d 30 pe.ce.t of the.r allocate. budge. to ve.e.able. on tomatoe. and potatoe.. The.gre.n be.n e.asticity is the.highe.t indicating that de.and for be.ns is highly re.ponsive.to any change. in the.price. The.e.pe.diture.e.asticitie. re.e.l that the.de.and on all ve.e.able. is e.pe.te. to grow ove. the.coming fe. ye.rs. High own-price.e.asticitie. of all ve.e.able. studie. sugge.ts that any change. in the.price. of the.e.crops could bring about a significant shift in fruits and ve.e.able.constanption patte.ns.
