By using emergy analysis theory and methods, we conduct quantitative analysis on the input and output of emergy, and sustainable development of agro-ecological system in Poyang Lake Area. The results show that compared with the national average, the environmental loading ratio is relatively low in this area; the net emergy yield rate is high; the sustainable development ability is strong. Finally according to the results of emergy analysis, corresponding countermeasures are put forward as follows: develop agriculture based on the existing rich natural resources; increase technological inputs; develop circular agriculture; promote sustainable agricultural development.

作者： Zhonghua Jia 1 , Rui Che 2 1 department of World Economy, economics and management School of Wuhan {3. Wuhan, china 2 Ningbo {3. of Technology, Ningbo, Zhejiang, china

Using the data from 1980 to 2010, this paper conducts an empirical research on regional disparities from the perspective of regional imbalances of foreign trade. The results show that regional disparities of china’s foreign trade are quite evident since 1980, but the imbalance level has gradually decreased in recent years. It is noted that the imbalances of foreign trade between the eastern and the central region are diminishing whereas the western region shows no obvious trend. Since 1992, china’s economic imbalance is mainly caused by the inter-regional imbalance of foreign trade, which on average accounts for 75 percent of the regional economic disparities. Besides, the regional imbalance of import trade has exerted greater impact on the regional disparities of economic growth than that of export trade imbalance has.

The study on the psychological contract in an enterprise is a popular and emerging topic in the field of Human Resources management. In order to solve the problems in induction training for fresh graduates, a variable questionnaire is designed in this paper. Firstly, the paper analyses the present situation of the induction training for fresh graduates in china, then it brings in the induction training for fresh graduates which is based on the psychological contract. Further, the paper combines their specialties to design the targeted questionnaire. Based on the precedent results, the paper gives four feasible suggestions, as well as providing theory guidance and policy advices for the induction training application of psychological contract. It was shown that psychological contract is important in induction training for fresh graduates.

＜正＞ The reformation of the economy system has led the functional department and status of the enterprises into a variable state. Under the condition of the market economy, the kernel of the enterprises’ functional department has diverted to that of marketing decision-making, which face to market and meet with the need of consumption. Assuredly, the kernel of marketing decision-making is to prognosticate the future market demand of the production of enterprises accurately, so that it can ensure and realize the maximum of the enterprises’ profit *** empirical research and the multi-regression technique, this paper analyzes the enterprises’ production demand forecast of the CMC （Global management Challenge, held every year globally） and changes most of uncontrollable factors of demand forecast to the controllable ones of the enterprises. The method we used to forecast demand by using the multi-regression technique is as follows;1. Look for the main factors which influence the demand of productions;2. Establish the regression model;3. Using the historical data, find the resolution of the correlative index and do the prominent test;4. Analyze and compare, regression, adjust parameter and optimize the regression model. Our method will make the forecast data closer to the actual prices of the future marketrequirement quantity in the production marketing decision-making of the enterprises and realize the optimizing combination and the working object with the minimum of the cost and the maximum of the profit. And it can ensure the realization of the equity maximum of the enterprises and increase the lifecycle of the production.
