推进农村经济改革和建设的新思路、新途径——山西省临汾地区发展小区域经济的调查

发轫于七十年代末期的我国农村经济体制改革,取得了巨大成就,写下了中国农业史上光辉的一页。但也应当看到,我国农村经济经过一段高速增长时期之后,自1985年起,开始步入了一个复杂而艰难的阶段。改革的进展速度和经济的增长速度,都出现了明显减缓的现象,粮食生产连年徘徊不前,乡村工业的优势开始减弱,农业面临后劲不足的问题。

Regional Disparities of China's Economic Development during 1992-2013——Based on DMSP/OLS Nighttime Lights Data of Cities

Balanced regional development is essential to China's economic stability and efficiency and achievement of the goal to build a moderately prosperous society in all respects. Based on the DMSP/OLS nighttime lights data of 291 cities at or above prefecture level during 1992-2013, this paper examines the regional disparities and trends of Chinese mainland's economic development. The findings are as follows:(1) During sample observation period, China's overall regional disparities generally declined despite some volatility; China's intra-regional disparities have been curbed yet a consistent framework for inter-regional economic coordination is lacking.(2) Southern coastal region contributes a significant share to China's overall regional disparities as the developed cities of Guangdong Province did not create a significant spatial spillover effect on neighboring regions.(3) According to the result of spatial Markov transition probability estimation, spatial factor has played a remarkable role in the evolution of China's regional economy and proximity to high-level regions will accelerate a region's transition toward higher levels.

A Systems Approach for Analyzing Vegetative and Soil Degradation in Arnigad Micro-watershed of Indian Himalayan Region

This study analyzes the vegetative and soil degradation,measured as biomass and soil loss,for Arnigad micro-watershed located in Indian Himalayan state of Uttarakhand,in systems framework by using dynamic linear programming bio-economic model.The focus is at investigating the effects of alternate policy regimes,i.e.,introduction of improved energy sources for cooking along with substitution of existing local livestock breeds with improved breed,reduction in human population growth and introduction of high yielding varieties of main crops including paddy,maize and wheat.The model horizon extended over a period of 25 years,i.e.,from 2006 to 2030.It was found that the model scenario incorporating increased use of improved energy sources along with substitution of local cows by improved cows could be the most effective policy option in reducing vegetative and soil degradation.The vegetative biomass density declined to 19.76% compared to 35.24% in the BASE scenario and soil erosion loss was also lowered by 29.13%.Also,the reduction of population growth rate to half of the BASE scenario led to minor improvements in degradation.Introduction of high yielding varieties of main crops slightly increased vegetative degradation but reduced soil loss(8.35%) with respect to the BASE scenario.Such a phenomenon could be explained in terms of changed crop mix resulting in reduced amount of crop by-products requiring increased lopping of tree branches for animal fodder.The policy option of the increased use of improved energy sources along with substitution of improved breed of cows resulted in 9.58% higher income.Introduction of high yielding varieties of crops led to 1.92% increase in income,but the income decreased by 1.25 % when population growth was reduced to half.The usefulness of the model lies in analyzing the systems behavior in its entirety where the results can predict the possible direction of change as a result of manipulation in alternate economic regimes.

Competitive Advantages and Clustering of SMEs： An Analysis of Clustering Effect on Competition in Small-Scale Enterprises in Istanbul

According to Michael Porter＇s Diamond Model, a business cluster is defined as geographic concentration of inter-connected companies and institutions working in a common industry. In addition, clusters encompass an array of collaborating and competing services and providers that create a specialized infrastructure, which supports the cluster＇s industry. The economic cluster model, represents a synergy, a dynamic relationship and a network between not only the companies that comprise a cluster but also the successful partnering of the stakeholders. Today in all over the world, successful clusters have established a greater competitive advantage and wealth creation for their regions when compared to companies not in a cluster. Given this success more policy makers and regions are considering fostering cluster development as building blocks of regional economies. Research is planned and performed for understanding the clustering in SMEs （small and medium enterprises） industrial estate in Istanbul if it gives a competitive advantage to the cluster members or not. It is performed to determine and satisfy the lack of knowledge about the small and medium enterprises＇ issues, technologic systems, production quality standards, capacity usage ratios, interactions with other firms, habits of following the technologic improvements and clustering effects on the members.
