产业结构、技术进步、对外开放程度与单位GDP能耗——基于省级面板数据和协整方法

运用面板协整技术研究各影响因素对中国各省区单位GDP能耗的影响方向和影响强度,面板单位根检验和协整检验表明,全国各区域单位GDP能耗和各影响因素均为一阶单整变量,存在协整关系。协整方程表明,产业结构对单位GDP能耗的负影响东北最大,中部最小,西部为正影响;技术进步对单位GDP能耗的负影响东部最大,西部其次,中部最低;对外开放程度对单位GDP能耗的负影响西部最大,东北最小,中部为正影响。误差修正模型表明,东北调整到均衡状态的速度最快。根据实证结果,建议由此在制定"十二五"节能降耗目标时应该分区域实行不同的降耗目标和实现路径。     

Simulation and Analytical Approach to the Identification of Significant Factors

We develop our previous works concerning the identification of the collection of significant factors determining some, in general, nonbinary random response variable. Such identification is important, e.g., in biological and medical studies. Our approach is to examine the quality of response variable prediction by functions in (certain part of) the factors. The prediction error estimation requires some cross-validation procedure, certain prediction algorithm, and estimation of the penalty function. Using simulated data, we demonstrate the efficiency of our method. We prove a new central limit theorem for introduced regularized estimates under some natural conditions for arrays of exchangeable random variables.

Exact and Approximate Statistical Inference for Nonlinear Regression and the Estimating Equation Approach

The exact density distribution of the non‐linear least squares estimator in the one‐parameter regression model is derived in closed form and expressed through the cumulative distribution function of the standard normal variable. Several proposals to generalize this result are discussed. The exact density is extended to the estimating equation (EE) approach and the non‐linear regression with an arbitrary number of linear parameters and one intrinsically non‐linear parameter. For a very special non‐linear regression model, the derived density coincides with the distribution of the ratio of two normally distributed random variables previously obtained by Fieler almost a century ago, unlike other approximations previously suggested by other authors. Approximations to the density of the EE estimators are discussed in the multivariate case. Numerical complications associated with the non‐linear least squares are illustrated, such as non‐existence and/or multiple solutions, as major factors contributing to poor density approximation. The non‐linear Markov–Gauss theorem is formulated on the basis of the near exact EE density approximation.     

海洋能发对社会经济影响的评价研究简

近年来国家对海洋能的发展越来越重视，但关于如何评价海洋能开发效益的研究还处于起步阶段，并未形成统一的规范。文章坚持主观与客观评价、传统与现代评价相统一的原则，对海洋能开发对社会经济影响的评价技术规范体系进行了设计，从综合评价角度分析海洋能开发对社会经济的影响。同时引入系统工程方法，通过建立系统动力学模型，静态模拟出海洋能开发对社会经济影响的运行机制，为进一步动态仿真海洋能开发效益提供了重要借鉴。     

Toeplitz lemma,complete convergence,and complete moment convergence

In this paper, we study the Toeplitz lemma, the Cesàro mean convergence theorem, and the Kronecker lemma. At first, we study “complete convergence” versions of the Toeplitz lemma, the Cesàro mean convergence theorem, and the Kronecker lemma. Two counterexamples show that they can fail in general and some sufficient conditions for “complete convergence” version of the Cesàro mean convergence theorem are given. Second, we introduce two classes of complete moment convergence, which are stronger versions of mean convergence and consider the Toeplitz lemma, the Cesàro mean convergence theorem, and the Kronecker lemma under these two classes of complete moment convergence.
