I recently discovered an interesting overview, Supply Chain Perspectives and Issues: A Literature Review by Park, Nayyar & Low (2013), which has been published by the World Trade Organization. It explicitly distinguishes between the economic and business perspectives on supply chains. Indeed, many supply chain phenomena take place somewhere between these two worlds, as the “supply chain” system is broader than the “organization” system and also different from the “market” and “economy” systems. As the authors write, “[t]he economics perspective attempts to understand [supply chains] through trade theory, along with the motivations for specialisation and production location decisions. […] The focus in the business literature is more concerned with a firm-level perspective.” My impression is that SCM research has often covered the latter perspective but neglected the former one. The authors also link the supply chain management and global value chain literatures, which is a promising path to go, as I have also highlighted in a previous post.
I recently found an interesting report: Value of Air Cargo: Air Transport and Global Value Chains, published by Developing Trade Consultants. The authors write: “Global Value Chains (GVCs) represent a new trade and development paradigm. They enable countries to specialize in narrowly defined tasks, such as component production, research and development, or assembly. Tasks originating in a variety of countries are then combined through a complex network of trade and investment links, to produce finished goods […].” The report analyzes data to investigate the linkages between GVC trade and air cargo. It shows that countries engage in more trade in value terms if they have better air cargo connectivity – which is measured by an “Air Connectivity Index”. A strong association is found between a higher ACI score (i.e. stronger air connections to more countries) and a higher total trade value: “[O]ne percent increase in air cargo connectivity is associated with a 6.3% increase in total exports and imports.”
I am happy to share the following guest post by Dexter Galvin, Head of Supply Chain, CDP. Thank you for contributing to my blog.
Our latest Global Supply Chain Report 2017, written in partnership with BSR and the Carbon Trust, revealed emissions savings of 434 million tonnes disclosed by suppliers in 2016. That’s more than the annual emissions of France, and it shows that the supply chain is a critical component – the missing link – in securing our sustainable, low-carbon future. Our data showed that supply chain action isn’t just about reducing emissions; it’s also good for the bottom line. Companies with emissions reduction projects disclosed cost savings of $12.4 billion as a result of their carbon-cutting measures – double what was reported in 2015. Almost half of the top 100 projects by savings were related to energy efficiency, and with a payback period of three years or less, the majority of projects had an attractive investment profile too. While the savings achieved by suppliers were certainly impressive, around half of the 4,300 companies we surveyed didn’t report any emissions reduction activities at all. So think what the impact could be – on costs and carbon levels – if they all took action?
Dexter runs the Supply Chain program at the global climate change NGO, CDP, from their London Headquarters. He has launched a number of important global initiatives to drive climate action in private and public sector supply chains, including CDP’s Action Exchange initiative.

Shifting from “company thinking” to “supply chain thinking” has successfully replaced the system, managers had in mind when making their decisions. This shift has put some of the parts of what has formerly been considered the company’s unmanageable environment into their unit of analysis. A supply chain, however, is per definition linear. In the age of sustainability, we might thus need to go one step further and shift from “linear thinking” towards “circular thinking”. The circular economy (or closed-loop supply chain) could replace the linear system by a circular system in the minds of decision makers. This is illustrated in a video released by the European Commission.
The following Google Ngram Viewer graph shows the frequency of the terms “supply chain”, “logistics” and “procurement” in books published between 1975 and 2008. It turns out that the use of the term “supply chain” accelerated in the late 1990s and overtook “logistics” in 2007. We can only speculate about the current use, as Google’s database ends in 2008.
We certainly all agree: Trust between supply chain partners has a lot of benefits. However, in their forthcoming study of trust in the buyer–supplier relationship, Villena and her co-authors argue that there is a “duality of trust”: Trust has benefits but it can also become dysfunctional if it is excessive. The results of their study show “that trust follows an inverted-U shape with performance”, i.e., at a certain point the negative effects offset the benefits of trust and performance declines. The authors also show that “[t]rust’s negative effects are more severe for those buyers that are highly dependent and operate in stable markets”. But why could trust ever be harmful? Well, trust might create “blind faith” into a supplier when the buyer is too optimistic. Another explanation could be that buyers might avoid tensions with suppliers that they otherwise trust – even if they observe declining performance. Trust can also increase reliance and unnecessary obligations that constrain the buyer.

What are the upcoming SCM trends? Firstly, in our recent research about “hot topics” in SCM, sustainability topped the list. Indeed, 2016 has, most probably, been Earth’s hottest year on record. Ask yourself: “What will be my contribution to revolutionize our business models and create truly sustainable supply chains?” Secondly, 2017 could become the year for supply chain managers, as an increasing number of companies realize that SCM belongs in the C-suite – and that this can make a difference! Another example is Lego, the toy maker, which has recently appointed a supply chain expert to become new CEO. Companies seem to understand that SCM is not just another name for logistics; it rather creates the smile of value creation. Finally, machine learning and artificial intelligence have recently made an astonishing leap forward. Not much imagination is needed to realize that this development is about to “disrupt” decision making in SCM. Why not let machines select your suppliers? Have a good new year!
