Establishment of Optimized Eco-productive Paradigm in the Farming-Pastoral Zone of Northern China

The farming-pastoral zone of northern China plays a dual role in ecological conditions and production and occupies an important position in the national economy. In this paper, the methodology of system engineering is introduced to construct and optimize an eco-productive paradigm system for the typical areas of the farming-pastoral zone. The system was constructed in the following steps: (1) design the framework of the paradigm system based on the data of physical site characteristics, biocommunities, production and economy, social culture and historical changes; (2) analyze the vegetation patterns, the interactions between vegetation and environmental factors (natural, social, economic, etc.) and the contributions of vegetation to the area, including the synthesis of the existing researches; and (3) provide the spatial arrangements of ecosystems and planning of each area, raise a comprehensive indicators of evaluation, evaluate the feasibility and soundness, and determine the optimum eco-productive paradigms for policy-makers which were land-use patterns within the threshold of ecological conservation. Three primitive paradigms of Maowusu (Mu Us) Ssandy Land, Loess Plateau and Huailai Basin in the farming-pastoral zone of northern China were proposed according to this paradigm system.

A Study on "Internet +" Eco-production and Eco-tourism Mode for Agricultural Enterprises

"Internet +" eco-production and eco-tourism carried out by agricultural enterprises is one of ways to increase income.Urban economic development index evaluation value(u_1),agricultural enterprises' eco-production and eco-tourism index evaluation value(u_2) and Internet popularity index evaluation value(u_3) constitute the ternary coupling system.The ternary coupling coordination degree(D_3) combined with u_2 can be used to judge whether the agricultural enterprises practise eco-production and eco-tourism mode.When u_2≥ 0.5000,D3≥0.6000,the autonomous mode for agricultural enterprises can be used; when 0.4000≤u_2< 0.5000,0.5000≤D_3< 0.6000,the mode of cooperation with travel agency can be used; when 0.3000 ≤u_2< 0.4000,0.4000 ≤D < 0.5000,the tourism business transfer mode can be used; when u_2< 0.3000,D < 0.4000,the tourism business should not be carried out.All the above four modes require "Internet +".

ECO-Case Based Reasoning Tool for Environmental Product Design

Case Based Reasoning(CBR)is one of the artificial intelligent methodologies that is widely used in problem solving by reusing the most similar previous experiences stored in the library.A framework of ECO-CBR for Life Cycle Assessment data collection has been used and the process was carried out using SolidWorks program.The practicality of the tool has been validated using case study,which then provides solution.The output enable researchers to determine forecast error and forecast accuracy,by valuing the calculation from Total Carbon Footprint,Energy Consumption,Air Acidification,and Water Eutrophication.ECO-CBR is able to assist designers in product design.Due to the limitation of environmental impact consideration in product sustainability,there is a demand to propose a tool that can assist designers to reduce environmental impact of product design at early stage.The model works as an essential guideline to lessen repeated mistakes in the product development process and help designers measure the risks before concluding ideal decisions.Minor errors that occur through the study showed that ECO-CBR is reliable to be implemented in order to find a better solution.

The Mechanism of Realizing the Value of Ecological Products and Case Studies

The article uses a case study approach to investigate the mechanisms of ecological product value realization,and influencing factors.Specifically,we use a case analysis framework based on the“economy-societynatural ecology”perspective to analyze and compare the three batches of“Typical Cases of Ecological ProductValue Realization”released by the Ministry of Natural Resources.We find:First,different modes of ecologicalproduct value realization exist.Different resource endowments,and institutional and environmental factors affectthe selection of the value realization modes.Second,certain obstacles also exist for realizing ecological productvalue,which are mainly reflected in the fact that the articulation of the individual,society,and government is not yetsufficiently close.Third,to promote the development of regional eco-products’mode and value conversion,the implementing party needs to guide the synergy between individual concepts,social participation,and governmentaltop-level design;rationally arrange the allocation of resource elements;mitigate elemental constraints;and proposeeffective technical means and optimization strategies according to the actual situation.

AN ECO- AND INNO-PRODUCT DESIGN SYSTEM APPLYING INTEGRATED AND INTELLIGENT QFDE AND TRIZ METHODOLOGY

The green environmental laws and regulations are legislated, implemented, and enforced in many countries and economic regions. The provision of green products and services are the fast growing trend in global consumer markets. Therefore, introducing new products with environmental considerations becomes critical for global brand manufacturers. This research depicts an integrated and intelligent eco- and inno-product design methodology to support environmental friendly green product development. The methodology adopts approaches, such as life cycle assessment （LCA）, quality function deploymnet for environement （QFDE）, theory of inventive problem solving （TRIZ） and back-propagation network （BPN） to achieve eco- and inno-design objectives. LCA evaluates and compares the environmental impacts of production. QFDE transforms high-level concerns of environment into design requirements. When there are many historical QFDE data, the BPN prediction model is trained and deployed to automate the specifications of green design improvement. TRIZ is to support the creation of innovative product design ideas effectively and efficiently during the concept design stage. Finally, this paper presents two eco-design cases of power adaptor to demonstrate the proposed methodology.

An Empirical Study on How the Development of Digital Economy Affects the Value Realization of Ecological Products

Empowering the value realization of ecological products with a digital economy is an important path for achieving the transformation of“two mountains”and the construction of ecological civilization.Based on the panel data of 30 provinces in China from 2011 to 2022,a fixed-effects model was used to empirically test the impact,heterogeneity and mechanism of the effects of the digital economy on the value realization of ecological products.This analysis revealed three key findings.(1)The digital economy has a significant driving effect on improving the ability to realize the value of ecological products,and this effect is still applicable in a variety of robustness tests such as shrinking the years,replacing explanatory variables,and endogeneity tests.(2)The rise of the digital economy affects the value realization of ecological products to different degrees in different regions,especially in the eastern region,while the effect in the central region is not obvious.(3)The analysis of mechanistic variables indicated that the digital economy has an impact on the value realization of ecological products through the development of green finance and government revenue.Therefore,the government should design differentiated and multi-level support policies for the realization of ecological product value according to the heterogeneity of natural resources,ecological potential and the levels of digital economy development in different regions,and it should strengthen the control of non-environmental protection behaviors of the enterprises.Enterprises should accelerate the digital transformation of the entire production,distribution,circulation and consumption chain of ecological products,and actively develop financial products and services that meet the characteristics and needs of ecological products.
