【学术会议的发言稿开场白】一

1. prologue

thank you, mr. chairman, for your gracious

introduction. i am honored to have the chance to address

you on this special occasion. the topic of my paper is

“transaction cost and farmers’ choice of agricultural

products selling”. the outline of my talk as follows.

the first part i want to introduce the background of this

research. the second part suggests a simple household

choice model .the third part covers the data used in this

research. and then, we introduce the empirical results.

finally, a simple conclusion is given.

2. introduction

well, let’s move on the first part of this

topic .the motivation of this work like this.

institutional economics posits that agents making

decisions on different types of transactions do so in a

costly way .for example , farmers deciding sell a

particular crop to whom base their decisions not only on

the price they expect to receive in each market choice

but also on additional costs related to transacting in

these markets.

i want to use a picture to illustrate it. for

example, given some market channels, farmers’ choices

can be regarded as equilibrium between the surplus and

the additional costs that related to

transacting .especially in developing countries, high-

value crop producers fully participate in the market and

the transaction cost has been the hard constraint to

farmers. furthermore, farmers’ market choices can be

taken as a choice dilemma of transaction cost and

production surplus. consequently, the scientific question

of this research is how transaction cost affects

planters’ choices.

3. methodology

let’s move to the theoretical model of our research.

consider a household model in one rotation. in stage 1 ,

famer η needs to allocate the input factors .this

process can qbe set into a function like this q q( p ,

w , z ) , qη means the output farmers decide qto produce

.p implies the output price w implies input price and.z:

is fixed input. once produce what and produce how many

are decided, next question to be considered is how much

products to be transacted in market. here we use three

cccη means how functions to describe this question. the

first equation, c p , z

much agricultural products used by famers themselves.

p implies the price the cagricultural product,z suggests

the fluctuation of cη. the second equation q q c, qη

means the amount of agricultural products transacted in

qnmarket. the third equationi q implies the amount

exchanged in nth time.

in stage 3, farmers will decide to sell the products

to whom. chanel j’s market price is

bdecided by an exogenesis price and farmers’

negotiating power.pijp*

jb(qi,zi)besides this, we use a matrix to show the

net profit of chanel jx ik ik, ik

and then farmers’ choice can be expressed in a

typical choice model

exp(xij)pr(jij|xik)1 exp(xij) k1

based on the choice model, another important concept

is famers’ channel choice .here, we set five types .they

rank by the market barriers. accordingly, we set a group
