江苏沿海地区城市化现状及存在问题浅析

2009年江苏沿海开发上升为国家战略。为了解该地区的发展态势,本文立足城市化视角,具体分析了该地区城市化现状及存在问题。通过客观考察,本研究发现该地区面临一些困境,包括城市化率偏低、城市经济薄弱、社会事业滞后、城市间分工合作不够协调等。不过,总体上江苏沿海面临的机遇依然多于挑战。     

Does a stricter enforcement policy protect the environment? A political economy perspective

The conventional wisdom suggests that a stricter enforcement policy can reduce pollution emissions. Nevertheless, this present paper argues that this assertion does not necessarily hold if the stringency of environmental regulation is subject to the influence of lobbying. A stricter enforcement policy increases the polluters’ expected financial burden, and induces them to exert greater political pressure on reducing the stringency of environmental regulation, thereby resulting in a larger amount of pollution emissions. We also show that tightening the enforcement policy can reduce efficiency. We highlight the possibility of policymaking being misguided due to overlooking the political effect of enforcement policy.

On the asymptotic normality of some unbiased estimates

Abstract

Let X _m(n) =(X _j , n, ..., X _{j m,n} ) be a subset of observations of a sample X_n = (X_1n X _2n ... , X _nn ). Here the X_jn 'S in Xn are not necessarily independent or identically distributed, and m(n) mayor may not tend to infinity as n tends to infinity. Suppose the joint density function h_n =h_n (x _m (n); θ) of the X _jn 's in Xm(n) is completely specified except the values of the parameters in the parameter vector θ = (θ1 θ2, ... , θ _k ), where θ belongs to a non-degenerate open subset H of the k-dimensional Euclidean space Rk and k?m(n).

Institutional-based antecedents and performance outcomes of internal and external green supply chain management practices

Green supply chain management (GSCM) has been a developing topic for at least a couple of decades. Over this time, significant complexities have been observed in its management. Helping to simplify and understand these complexities is necessary from both a practical and research perspective. Given this situation and to further enhance understanding of the topic and even supply chain management in general, this paper develops and empirically tests a theoretical model on the different types of institutional pressures motivating manufacturing enterprises to pursue green supply chain management (GSCM) practices and commensurate performance outcomes. Using a sample of 396 Chinese manufacturers, path analysis is used to evaluate the many structural links. The statistic results show that institutional pressures have driven the manufacturer adoption of internal GSCM practices which in turn relate to their external GSCM practices adoption. The statistic results also suggest that GSCM practices do not directly affect economic performance, but can improve it indirectly. This research contributes to the literature on institutional theory in corporate environmental practices. The research findings provide useful insights for managers seeking to adopt GSCM practices. The results also provide policy insights for professional organizations, regulators, and legislators to further promote GSCM.     

The role of domestic demand in the economic growth of Malaysia: a cointegration analysis

For the past four decades (1961-2000), the Malaysian economy grew at an impressive average rate of 6.8% per annum. The rapid growth has been attributed, in part, to the tremendous success in the export-oriented industrialization policy. Several empirical studies on export-led growth for Malaysia have, however, led to inconclusive and mixed results. This may be due to the exclusion of domestic demand in the bivariate or multivariate models used in the studies. This study re-examines the role of domestic demand in economic growth in Malaysia. Using a three-variable cointegration analysis, the study shows that there exist short run bilateral causalities among the three variables, which implies that both the export-led growth and domestic demand-generated growth hypotheses are at least valid in the short run. On the other hand, the results are not supportive of the export-led growth hypothesis in the long run. Instead, the highly significant positive impact of domestic expenditure on economic growth implies that use of domestic demand as the catalyst for growth is appropriate.
