我国西部地区的国企改制困境:一个文献综述

本文针对我国西部欠发达地区目前的国企改制困境问题,对国内外相关文献进行了综述分析,发现造成我国西部国企改制困境的原因中既有"外生"的因素,也有"内生"的因素.西部地区不利的自然禀赋、不合理的产业结构以及中央逆市场调控的政策等,造成西部市场机制发育迟缓,仅靠市场的力量无法消化国企改制的成本;而我国转轨时期特定的体制结构使得政府在国企改制成本支付过程中充满了机会主义行为.针对这种情况本文提出了相应的政策建议.     

External Debts,Institutions and Growth in SSA

The study investigates the impact of institutional quality on the external debt–growth nexus in SSA. Data from 36 SSA economies over the 1996–2013 periods were used. The results from the IV-System GMM imply that institutional quality has robust effects on the external debt–growth nexus. Thus, the impact of external debt on growth is through host nation’s institutional quality. However, the mediating effect of institutional quality on this nexus is up to a point. When a country is on the wrong side of the debt-laffer curve, external debt becomes irrelevant; and institutional quality can no longer help.     

我国东西部地区技术相似度测度与差异分析

采用标准的技术相似度测量方法,定量测度了我国东西部各省份间的技术相似度,发现西部与东部省份之间存在技术结构差异,与北京和上海的差距尤其显著。分别以与北京、上海的技术相似度为基准,对东西部省份进行排序,证实了我国各省份之间的技术结构和地理分布、经济水平类似,东西部也是具有明显差异的。并通过分析东部省份之间、西部省份之间以及东西部省份之间的技术相似度水平,以找出西部各省潜在的技术转移来源地。     

Land pressures,the evolution of farming systems,and development strategies in Africa: A synthesis

Evidence assembled in this special issue of Food Policy shows that rising rural population densities in parts of Africa are profoundly affecting farming systems and the region’s economies in ways that are underappreciated in current discourse on African development issues. This study synthesizes how people, markets and governments are responding to rising land pressures in Africa, drawing on key findings from the various contributions in this special issue. The papers herein revisit the issue of Boserupian agricultural intensification as an important response to land constraints, but they also go further than Boserup and her followers to explore broader responses to land constraints, including non-farm diversification, migration, and reduced fertility rates. Agricultural and rural development strategies in the region will need to more fully anticipate the implications of Africa’s rapidly changing land and demographic situation, and the immense challenges that mounting land pressures pose in the context of current evidence of unsustainable agricultural intensification, a rapidly rising labor force associated with the region’s current demographic conditions, and limited nonfarm job creation. These challenges are manageable but will require explicit policy actions to address the unique development challenges in densely populated rural areas.

Is fertiliser use inconsistent with expected profit maximization in sub‐Saharan Africa? “Evidence from Nigeria”

This article revisits a conventional wisdom that inorganic fertiliser use across sub‐Saharan Africa is too low. This expectation that more farmers should be using inorganic fertiliser, and at higher rates, implies it is profitable to use rates higher than observed if farmers are rational expected profit maximisers. We obtain consistent estimates of the effects of applied nitrogen on rice production. We find the yield response to applied nitrogen to be low in the main rice growing farming system. Farmer behaviour is not inconsistent with expected profitability which is limited by a low yield response to applied fertiliser, high transportation costs, and low selling prices for rice in rural areas. In particular, we do not find any farmers for whom applied nitrogen is profitable that are not using fertiliser in the study sample for each of our survey years (2010 and 2012).
